Objective: Children frequently experience pain and/or discomfort during dental treatment. Still, pain research in dentistry has mainly been performed on adults using quantitative methods while research on the child's perspective is scarce. This study aims to explore and describe children's experiences and/or thoughts regarding pain in conjunction with tooth extraction.

Material and methods: Interviews were carried out with twelve Swedish 10-16-year-olds who had recently undergone tooth extractions due to orthodontic reasons. Interviews were transcribed verbatim and analysed according to grounded theory.

Results: A core category was identified and named 'handling the unavoidable unknown'. The informants recalled experiences of pain and discomfort during extractions. However, instead of focussing on pain, they described an urge for more information about the procedure and what to expect in terms of pain and/or discomfort, during and/or after treatment. They stated that the levels of pain/discomfort were manageable, while the lack of information negatively affected their coping abilities, causing feelings of unease.

Conclusions: To improve patients' ability to deal with pain in conjunction with dental extraction, the dental team should ensure better and individually tailored information about the treatment. Thus, the use of psychological techniques is a cornerstone in pain management and must be reflected in clinical guidelines.

Objectives This study evaluates the agreement of data on dental caries between electronic dental records and data retrieved from the national SKaPa-registry (Swedish Quality Registry for caries and periodontal disease), with special reference to e/M in deft/DMFT.

Methods In a random sample of 500 6- and 12-year-old children having received dental care in 2014 in the county region of Värmland, Sweden, the diagnostic accuracy of data in electronic dental records with corresponding data obtained from the SKaPa-registry was compared by using Cohen’s Kappa and Intraclass correlation coefficient (ICC).

Results For dft/DFT the Kappa was 0.95, and ICC 0.98 (total population). For deft/DMFT in the total population the Kappa was 0.80 and ICC 0.96. For 6-year-olds (deft) the Kappa was 0.89 and ICC 0.99 and for 12-year-olds (DMFT) the Kappa was 0.70, and ICC 0.83. The corresponding figures for Kappa and ICC when excluding individuals without caries (deft/DMFT = 0) were: Total population 0.63 and 0.94; 6-year-olds 0.79 and 0.99; 12-year-olds 0.42 and 0.68.

Conclusion Agreement between data in the dental records and SKaPa was very high for dft/DFT confirming that transfer from the dental records to the SKaPa-registry is safe and correct. As the accuracy of deft/DMFT was considerably lower than for dft/DFT we advise against using deft/DMFT data from SKaPa for research purposes at this point.

There can be a lack of understanding of the vulnerable situation of children with disabilities and their families, even among professional caregivers whose mission is to protect the health and wellbeing of these children. Their respectful treatment should include knowledge, empathy, humanity, and an open and sympathetic dialogue. This book provides an overview of knowledge and literature review of children and adolescents with special care needs that contribute to the respect and understanding of children with disabilities and their families. It also explains possible reasons for different outcomes in research studies and why there is a lack of knowledge in some areas concerning these children. 

Research on children with disabilities is considerable but often can be difficult to access on many levels, which means it does not always benefit those who need this knowledge. This compact book addresses this by presenting the international research in the field in an understandable way for people who work with children with disabilities and their families. The authors provide a broad picture of the background, reality of life, opportunities for professional help and support, as well as outlook of these children and families. Among the topics covered:

• The Health and Well-being of Children with Disabilities
• The Health and Well-being of Relatives
• Occupation
• On the Road to Adulthood

Children with Special Needs: An Overview of Knowledge on Disability is pertinent reading for students in all areas of health care (including nursing and psychology), social work, sociology, and education aimed at children and young people. The text also would be of interest to those who practice in these areas and/or encounter children with disabilities in their daily work.

Introduction and objective: Radiographic evaluation of the maturity of mandibular third molars is a common method used for age estimation of adolescents and young adults. The aim of this systematic review was to examine the scientific base for the relationship between a fully matured mandibular third molar based on Demirjian's method and chronological age, in order to assess whether an individual is above or below the age of 18 years.

Methods: The literature search was conducted in six databases until February 2022 for studies reporting data evaluating the tooth maturity using Demirjian´s method (specifically stage H) within populations ranging from 8 to 30 years (chronological age). Two reviewers screened the titles and abstracts identified through the search strategy independently. All studies of potential relevance according to the inclusion criteria were obtained in full text, after which they were assessed for inclusion by two independent reviewers. Any disagreement was resolved by a discussion. Two reviewers independently evaluated the risk of bias using the assessment tool QUADAS-2 and extracted the data from the studies with low or moderate risk of bias. Logistic regression was used to estimate the relationship between chronological age and proportion of subjects with a fully matured mandibular third molar (Demirjian´s tooth stage H).

Results: A total of 15 studies with low or moderate risk of bias were included in the review. The studies were conducted in 13 countries and the chronological age of the investigated participants ranged from 3 to 27 years and the number of participants ranged between 208 and 5,769. Ten of the studies presented the results as mean age per Demirjian´s tooth stage H, but only five studies showed the distribution of developmental stages according to validated age. The proportion of subjects with a mandibular tooth in Demirjian´s tooth stage H at 18 years ranged from 0% to 22% among males and 0 to 16% in females. Since the studies were too heterogenous to perform a meta-analysis or a meaningful narrative review, we decided to refrain from a GRADE assessment.

Conclusion: The identified literature does not provide scientific evidence for the relationship between Demirjian´s stage H of a mandibular third molar and chronologic age in order to assess if an individual is under or above the age of 18 years.

This review aimed to update the clinical practice guidelines for managing adults with 22q11.2 deletion syndrome (22q11.2DS). The 22q11.2 Society recruited expert clinicians worldwide to revise the original clinical practice guidelines for adults in a stepwise process according to best practices: (1) a systematic literature search (1992-2021), (2) study selection and synthesis by clinical experts from 8 countries, covering 24 subspecialties, and (3) formulation of consensus recommendations based on the literature and further shaped by patient advocate survey results. Of 2441 22q11.2DS-relevant publications initially identified, 2344 received full-text review, with 2318 meeting inclusion criteria (clinical care relevance to 22q11.2DS) including 894 with potential relevance to adults. The evidence base remains limited. Thus multidisciplinary recommendations represent statements of current best practice for this evolving field, informed by the available literature. These recommendations provide guidance for the recognition, evaluation, surveillance, and management of the many emerging and chronic 22q11.2DS-associated multisystem morbidities relevant to adults. The recommendations also address key genetic counseling and psychosocial considerations for the increasing numbers of adults with this complex condition.

This review aimed to update the clinical practice guidelines for managing children and adolescents with 22q11.2 deletion syndrome (22q11.2DS). The 22q11.2 Society, the international scientific organization studying chromosome 22q11.2 differences and related conditions, recruited expert clinicians worldwide to revise the original 2011 pediatric clinical practice guidelines in a stepwise process: (1) a systematic literature search (1992-2021), (2) study selection and data extraction by clinical experts from 9 different countries, covering 24 subspecialties, and (3) creation of a draft consensus document based on the literature and expert opinion, which was further shaped by survey results from family support organizations regarding perceived needs. Of 2441 22q11.2DS-relevant publications initially identified, 2344 received full-text reviews, including 1545 meeting criteria for potential relevance to clinical care of children and adolescents. Informed by the available literature, recommendations were formulated. Given evidence base limitations, multidisciplinary recommendations represent consensus statements of good practice for this evolving field. These recommendations provide contemporary guidance for evaluation, surveillance, and management of the many 22q11.2DSassociated physical, cognitive, behavioral, and psychiatric morbidities while addressing important genetic counseling and psychosocial issues.& COPY; 2022 American College of Medical Genetics and Genomics.

Aim

Sweden´s first multidisciplinary children's advocacy centre (CAC) was founded in 2005 as a collaborative practice between child protection services, the legal system and health care in response to police-reported child abuse. CACs were introduced in the county of Skåne in 2007. The aim of the study was to describe the health of children investigated at the CAC in Lund, and to examine whether the CAC model of collaboration responded to the healthcare needs of these children.

Methods

All children aged 0–17 years investigated at the CAC in 2015 were included in this retrospective study. We reviewed the CAC files and the children's medical and dental records from one year prior to, until one year after their assessment at the CAC.

Results

Our review of the medical and dental records (n = 298) showed a high prevalence of mental, dental and physical ill-health. After the CAC joint meeting, only 1% of the children were referred for a medical examination and 4% for a focused forensic evaluation.

Conclusion

Our study demonstrates limitations in the CAC process in responding to extensive health issues of the young victims of crime. We suggest mental, dental and physical health assessments to be statutory in CACs.

The aim was to study general dental practitioners’ knowledge and attitudes on pain and pain management in children and adolescents, using a multidimensional questionnaire.There is little information on dentists’ views on pain in children. The research question was how attitudes and knowledge may correlate to the dentists’ age, sex,years of professional experience, the proportion of working time devoted to treating children and adolescents, as well as being a parent. At the time of the study, 387 general dentists working for the Public Dental Service participated in a web-based, multidimensional validated questionnaire holding the categories (A) views on the care of children in pain, (B) physiology, (C) pain alleviation, (D) medication, (E) sociology/psychology,(F) Pain assessment instruments and methods, (G) non-medication methods of pain alleviation, and (H) documentation of pain management. The age categories were given as; below 25, 25-35, 36-45, 46-55years, and older than 55 years of age.71% of the responders were female. The dentists’ age cohort, as well as the years of professional experience, tended to make a difference as to the pain interventions in children and adolescents (P < 0.03). The female dentists, in comparison to the male dentists, conveyed different pain treatment strategies (P < 0.03). The proportion of working time devoted to treating children and adolescents, as well as being a parent, did not show significant differences regarding pain strategies. Associations were observed between the age of the dentists studied, the number of years as professionals and the knowledge and attitudes that benefit children's pain treatment. Being a parent was not significant. In this studied group, female dentists displayed significantly more care regarding pain management, than did their male colleagues. Furthermore, the study highlighted the need for a short questionnaire, user-friendly yet with retained multidimensionality.

The United Nations (UN) Convention on the Rightsof the Child, states that all children should havethe same right to the highest attainable standardof health. This should be known by everyone whoworks with children. Despite good oral health in theNordic countries, studies show that children livingin socially deprived environments have a greaterincreased risk of poor oral health. These childrenare not reached by preventive measures, they morefrequently do not show up for dental appointmentsand they receive less dental care than others. Therefore, in addition to a more general preventive andpopulation-based method, a special high-risk approach is also needed to reach children in socially deprived areas. It is also important that promotion and preventive efforts start from an early age.There are large knowledge gaps regarding the effects of different preventative and treatment strategies, and health economic analyzes are rare. It is achallenge to systematically document and evaluate oral health promotion and prevention directed atchildren in socially vulnerable environments to enable research. There is a need for interdisciplinaryresearch that includes clinicians. The vision mustbe health equity and that both health promotionand preventive measures contribute to closing theoral health gap between different social groups. l

Background

The Swedish Quality Registry for caries and periodontal disease (SKaPa) automatically collects data on caries and periodontitis from patients’ electronic dental records. Provided the data entries are reliable and accurate, the registry has potential value as a data source for registry-based research. The aim of this study was to evaluate the reliability and accuracy of the SKaPa registry information on dental caries in 6- and 12-year-old children.

Method

This diagnostic accuracy study compared dental caries data registered at an examination with dental health status registered in the patient’s electronic dental records, and with corresponding data retrieved from the SKaPa registry. Clinical examinations of 170 6- and 12-year-old children were undertaken by one of the researchers in conjunction with the children’s regular annual dental examinations where the number of teeth were registered, and dental caries was diagnosed using ICDAS II. Teeth with fillings were defined as filled and were added to the ICDAS II score and subsequently dft/DFT was calculated for each individual. Cohen’s Kappa, the intraclass correlation coefficient (ICC), and sensitivity and specificity were calculated to test the agreement of the ‘decayed and filled teeth’ in deciduous and permanent teeth (dft/DFT) from the three sources.

Results

Cohen’s Kappa of the dft/DFT-values was calculated to 0.79 between the researcher and the patient record, to 0.95 between patient dental record and SKaPa, and to 0.76 between the researcher and SKaPa. Intraclass correlation coefficient (ICC) was calculated to 0.96 between the researcher and the patient journal, to 0.99 between the patient dental record vs. SKaPa, and to 0.95 between the researcher and SKaPa.

Conclusion

The SKaPa registry information demonstrated satisfactory reliability and accuracy on dental caries in 6- and 12-year-old children and is a reliable source for registry-based research.

AIM: Decades of research confirm that children and adolescents in out-of-home care (foster family, residential care) have much greater healthcare needs than their peers. A systematic literature review was conducted to evaluate organizational healthcare models for this vulnerable group. METHODS: A systematic literature search was undertaken of the following databases: Academic Search Elite, CENTRAL, Cochrane Database of Systematic Reviews, Cinahl, DARE, ERIC, HTA, PsycInfo, Psychology and Behavioural Sciences Collection, PubMed, SocIndex. Randomized and non-randomized controlled trials were to be included. Two pairs of reviewers independently assessed abstracts of the identified published papers. Abstracts meeting the inclusion criteria were ordered in full text. Each article was reviewed independently, by pairs of reviewers. A joint assessment was made based on the inclusion criteria and relevance. Cases of disagreement were resolved by consensus discussion. RESULTS: No study with low or medium risk of bias was identified. CONCLUSION: In the absence of studies of acceptable quality, it is not possible to assess the impact of organizational models intended to ensure adequate health and dental care for children and adolescents in out-of-home care. Therefore, well-designed follow-up studies should be conducted following the implementation of such models. This article is protected by copyright. All rights reserved.

Background: Obesity is a multifactorial disease that is increasing worldwide and is caused by different environmental and genetic factors, with an increase in the consumption of high-energy–containing food and a decrease in physical activity constituting two of the main reasons. Sweet taste perception may have an effect on the subject’s dietary choices and affect his or her predisposition to obesity. Objectives: The aim was to study the sweet taste perception and dental caries in relation to body mass index (BMI) in 13–15-year-old schoolchildren from three different countries and to compare the BMI among the countries. Design: The sweet taste perception level, determined as the sweet taste threshold and preference, was assessed in a total of 669 schoolchildren from Italy, Mexico and Saudi Arabia, examined in school settings. Height and weight were collected and BMI was calculated, after which the children were grouped as underweight, normal, overweight, and obese. For caries registration, the International Caries Detection and Assessment System and Decayed Missing Filled Surfaces indices were used. Results: A statistically significant difference was found for BMI among the children from the three countries (p < 0.001), with the highest mean found among Saudi children, followed by Mexican and Italian children. A statistically significant difference regarding sweet taste threshold when comparing the BMI groups was only found for Saudi Arabia (p < 0.01). No significant correlation was found between BMI and sweet taste threshold or preference and dental caries variables, respectively. Conclusions: BMI was found to differ between countries, with a further significant difference among the groups among the Saudi Arabia schoolchildren.

Background There is an uncertainty regarding how to optimally prevent and/or reduce pain after dental treatment on children and adolescents. Aim To conduct a systematic review (SR) and health technology assessment (HTA) of oral analgesics administered after dental treatment to prevent postoperative pain in children and adolescents aged 3-19 years. Design A PICO-protocol was constructed and registered in PROSPERO (CRD42017075589). Searches were conducted in PubMed, Cochrane, Scopus, Cinahl, and EMBASE, November 2018. The researchers (reading in pairs) assessed identified studies independently, according to the defined inclusion and exclusion criteria, following the PRISMA-statement. Results 3,963 scientific papers were identified, whereof 216 read in full text. None met the inclusion criteria, leading to an empty SR. Ethical issues were identified related to the recognized knowledge gap in terms of challenges to conduct studies that are well-designed from methodological as well as ethical perspectives. Conclusions There is no scientific support for the use or rejection of oral analgesics administered after dental treatment in order to prevent or reduce postoperative pain in children and adolescents. Thus, no guidelines can be formulated on this issue based solely on scientific evidence. Well-designed studies on how to prevent pain from developing after dental treatment in children and adolescents is urgently needed.

PURPOSE: To study pain perception in 10-15-year-olds, during and after uncomplicated extractions of bilateral maxillary premolars. The study investigated pain's natural course and made comparisons between the first and second extractions. METHODS: 31 Swedish children in need of orthodontic treatment were identified and consecutively enrolled. Tooth extractions followed a standardised protocol and the two teeth were extracted with at least 10 days between. The participants rated pain intensity using visual analogue scale (VAS) at 14 different time points from treatment and 7 days forward. RESULTS: The pain intensity profile followed the same pattern for all patients. Pain intensity peaked 2 h after extractions (mean VASPI 27.3, SD 20.8; median 23.0) when moderate pain intensity (VASPI >/= 40) was registered for 16 (28%) of 57 cases. After that, there was a rapid decrease in pain intensity notable already at 4 h after extractions. There were no statistically significant differences in any VASPI measurements between the first and second extractions, sexes, or different age groups. CONCLUSIONS: The majority of the participants who undergo uncomplicated bilateral extraction of maxillary premolars experience mild to moderate levels of postoperative pain during a short period of time, with no differences between the first and second extractions. Bilateral tooth extractions is a suitable model for further studies on pain management.

OBJECTIVES: To evaluate tooth development and calculate dental maturity score in prematurely born children and to compare the findings with full-term born children. MATERIAL AND METHODS: Nine-year-old preterm children were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before week 29), and the other included 38 very preterm children (born during weeks 29 to 32). Panoramic radiography was performed on each child and the preterm children were compared with 42 full-term born children. Five observers independently assessed the tooth development stages for all teeth in the left mandible (31-37) on the panoramic radiographs according to the method described by Demirjian et al. (Hum Biol 45:211-227, 1973). Data from tooth development stages were compiled and converted into a dental maturity score for each group. Kappa values were calculated for intra- and inter-observer agreement. RESULTS: When the different development stages for each individual tooth were compared, all observers presented a significant delay in the maturity of tooth 37 for the extremely preterm group (p

We used Swedish national registers to analyse dental health care among young adults with childhood experience of out‐of‐home care (OHC), in Cox regression analyses. All 1.7 million Swedish residents born in 1980–1994 were included, of whom 4% had been in OHC. The population was followed up in the Dental Health Register from age 20 to 29, during the period 2009–2014. We found that persons with short or long OHC experience made emergency dental care visits more often than their majority‐population peers: 17–23% versus 9–10%, (adjusted Hazard ratios [HR:s] 1.60–2.02); they more often had tooth extractions, 9–12% versus 3% (HR:s 2.33–3.03); but less regularly visited a dentist for planned check‐ups, 61–77% versus 80–87% (HR:s 0.76–0.78). Since dental health in young adulthood reflects dental health and dental care in childhood, the findings of this study call for improved preventive dental health care for children in OHC.

AIM: This study aimed to investigate Swedish dentists' attitudes regarding pain management strategies for treating children and adolescents. It assessed recommendations for pre- and postoperative analgesics, and use of local anaesthesia, and whether application of these strategies differs between general dental practitioners (GDPs) and specialists in paediatric dentistry (SPDs). DESIGN: We invited all GDPs (n = 807) in southern Sweden (Region Skåne), and all registered SPDs (n = 122) working in Sweden (929 actively practising dentists under age 65 years) to participate in a postal survey on pain management in paediatric dental care. RESULTS: The SPDs reported using all types of pain-reducing strategies more frequently than GDPs except local anaesthesia when extracting a permanent premolar, which SPDs and GDPs used equally often. Preoperative analgesic use was greater among SPDs than GDPs. GDPs used local anaesthesia less frequently for filling therapy in primary teeth than in permanent teeth. CONCLUSIONS: SPDs recommend preoperative analgesics more often than GDPs do. GDPs seem to underuse local anaesthetics when treating children and adolescents. SPDs also use pain management strategies more frequently than GDPs. Among GDPs, pain management is less frequent when treating primary teeth than permanent teeth.

BACKGROUND: The European Academy of Paediatric Dentistry (EAPD) proposes this best-practice guidance to help practitioners to decide when and how to use local analgesia to control pain in children, adolescents, and medically compromised individuals during the delivery of oral health care. METHODS: A search of different databases was conducted using all terms relevant to the subject. Relevant papers were identified after a review of their titles, abstracts or full papers. Three workshops were held during the corresponding EAPD interim seminar in Torino (Italy) in 2017. Several statements were agreed upon and, furthermore, knowledge gaps were identified. RESULTS: An important outcome was that when local analgesia administered appropriately-correct choice of agent(s) and dosage, proper route of administration-it is, firstly, clinically effective for pain-control in treating children and, secondly, it carries a very low risk of morbidity including adverse or side-effects. Furthermore, several gaps in knowledge were identified during the workshop which indicates future research needs. Most importantly it remains unsatisfactory that in several European countries the most frequently used injectable local analgesic agent, articaine, is not approved for usage in children below the age of 4 years. CONCLUSION: When considering the dental demand to treat vulnerable (medically compromised) children and adolescents in a safe, painless, less-invasive and effective way, there seems to be an urgent need to close these gaps in knowledge.

PURPOSE: To evaluate the evidence supporting effects and adverse effects of local analgesia using different pharmacological agents and injection techniques during dental treatment in children and adolescents aged 3-19 years. METHODS: A systematic literature search of databases including PubMed, Cochrane, and Scopus was conducted in November 2016. The PRISMA-statement was followed. Two review authors independently assessed the selected randomised control trials for risk of bias and quality. RESULTS: 725 scientific papers were identified. 89 papers were identified to be read in full text of which 80 were excluded. Finally, 9 papers were evaluated for quality and risk of bias. Many of the included papers had methodological shortcomings affecting the possibility to draw conclusions. Information about ethical clearance and consent were missing in some of the included papers. No alarming adverse effects were identified. One study was assessed as having low risk of bias. This reported inferior alveolar nerve block to be more effective than buccal infiltration for dental treatment of mandibular molars, while no differences were found regarding pharmacological agents. CONCLUSIONS: At present, there is insufficient evidence in support of any pharmacologic agent or injection technique as being superior compared to others. There is a need for more rigorous studies which also handle the ethical issues of including children in potentially painful studies.

PURPOSE: To describe and analyse dental care and treatment modalities for children with complex disabilities from a biopsychosocial perspective, with special focus on dental treatment under general anaesthesia (GA) and its relationship to child's functioning. METHOD: An ICF-CY Checklist for Oral Health was completed using structured interview, direct observations, and dental records for patients attending a specialist paediatric dentistry clinic. Descriptive and comparative data analysis was performed. Performance qualifiers from the ICF-CY component Activities and participation were used to calculate functional factors. RESULTS: Median referral age was 1.5 years and the majority were referred by their paediatrician. Almost all visited a dental hygienist regularly. Dental treatment under GA was common and was combined in 78% of sessions with medical treatment. Children with limitations in their interpersonal interactions and relationships were most likely to have dental GA. CONCLUSION: Children without caries experience had been referred for specialist dental care at an earlier age than children with caries experience. GA was a common treatment modality and dental and medical treatments were coordinated under the same GA for a majority of children. By using the ICF-CY, it was possible to identify functional limitations characterising children with disabilities that require dental treatment under GA. Implications for Rehabilitation Early referral to a specialist in paediatric dentistry is valuable for oral disease prevention in children with disabilities. Availability of dental treatment under general anaesthesia (GA) is also important. Combining dental and medical interventions during the same GA session optimises resources both for the individual and for the health organisation. Children with limitations in interpersonal interactions and relationships are more likely to need dental treatment under GA than other children.

Dietary habits and, in particular, the intake frequency of sucrose are of major importance for the development of dental caries. The perception of sweet taste is believed to have an influence on sucrose intake and therefore affects the predisposition to dental caries. The aim was to study the caries experience and sweet taste perception and to further analyze the possible relationship between the 2 tested variables in 13- to 15-year-old children from 3 different geographical areas. A cross-sectional survey comprising 669 children (220 Italian, 224 Mexican, and 225 Saudi Arabian) was conducted. The children were examined in their school setting. A sweet taste perception level was determined by the sweet taste threshold (TT) and sweet taste preference (TP). The sweet test was performed with sucrose solutions varying in concentration from 1.63 to 821.52 g/L. The International Caries Detection and Assessment System (ICDAS) and DMFS indices were used to diagnose caries. The highest mean value for TT was found for Italian children followed by Saudi and Mexican. Saudi schoolchildren showed the highest mean values for TP and DMFS, followed by Italian and Mexican. A statistically significant difference for TP, TT, DMFS, and initial caries was found between the 3 countries. A weak yet positive correlation was found between taste perception (TT and TP) versus DMFS and manifest caries in all 3 countries (r = 0.137-0.313). The findings of the present study showed a variation in sweet taste perception between the 3 countries, which may influence the caries outcome of the children in the individual countries.

BACKGROUND: The UN Convention on the Rights of the Child gives all children right to the highest standard of services for treatment and rehabilitation. For children with disabilities, sedation and general anaesthesia (GA) are often indicated for dental treatment; however, accessibility to this varies. The International Classification of Functioning, Disability and Health - Child and Youth version (ICF-CY) enables a biopsychosocial description of children undergoing dental treatment. AIM: To investigate conscious sedation and GA in children with complex disabilities and manifest caries and analyse how caries, child functioning, and dental service organisation relate to dental GA (DGA), comparing Argentina, France, and Sweden using the ICF-CY. DESIGN: Quantitative, cross-sectional; data collected through structured interviews, observation, and dental records. RESULTS: Sedation and DGA were common. Children with limitations in interpersonal interactions and relationships were more likely to have had DGA (OR: 5.3, P = 0.015). Level of caries experience was strongly correlated with experience of DGA. There were significant differences between countries regarding caries prevalence, sedation, DGA, and functional and environmental factors. CONCLUSIONS: Although caries experience and child functioning are important, dental health service organisation had the most impact on the incidence of DGA, and for the use of conscious sedation, for children with complex disabilities.

Dental care for children with disabilities – ethical considerations All dental care demands an ethical approach, maybe even more so in child dental care. Today more children with disabilities or longterm illness come to the dentist. How these children should be met and cared for does not differ from other patients, but in dental care for children with disabilities and long-term illness it may be more likely for situations and ethical dilemmas to evolve, where the dentist must stop, reflect, and analyze before continuing with treatment. Autonomy, integrity, and informed consent are important concepts when meeting patients and parents. The dentist also has to be prepared to sometimes step in and substitute autonomy.

AIM: This was, firstly, to study the occurrence of oral pain and discomfort, using the Dental Discomfort Questionnaire (DDQ), in children and adolescents with intellectual or physical disabilities, compared with controls. Secondly, was to analyse the relationship between pain and discomfort, as measured by the DDQ, and dental health, as well as oral hygiene habits and dietary habits. METHODS: The study included 135 children and adolescents (12-18 years), registered at the Child and Adolescent Habilitation Unit in Göteborg and Södra Bohuslän, Sweden, and 135 gender- and age-matched controls. The children's legal guardians completed a questionnaire comprising the DDQ and questions on oral hygiene and dietary habits. Data on dental health were retrieved from dental records. RESULTS: The DDQ total mean score was higher for the study group, compared with the control group, 3.2 (SD 2.9) vs. 1.6 (SD 2.0), respectively (p = 0.001). Furthermore, children and adolescents with a severe intellectual disability had higher total mean DDQ scores than children with a mild intellectual disability, 4.8 (SD 4.2) vs. 2.4 (SD 2.9), respectively (p = 0.034), and also higher than children with a physical disability, 2.2 (SD 2.1) (p = 0.012). There were no differences in DMFT between children with disabilities and age-matched controls. There was no relationship between the DDQ scores and oral hygiene/dietary habits in children with disabilities. CONCLUSIONS: Children and adolescents with intellectual or physical disabilities experienced oral discomfort and pain more often than matched controls. Dental health expressed as DMFT could not be related to the DDQ responses.

OBJECTIVES: To identify, appraise and summarize existing knowledge and knowledge gaps in practice-relevant questions in pediatric dentistry. METHODS: A systematic mapping of systematic reviews was undertaken for domains considered important in daily clinical practice. The literature search covered questions in the following domains: behavior management problems/dental anxiety; caries risk assessment and caries detection including radiographic technologies; prevention and non-operative treatment of caries in primary and young permanent teeth; operative treatment of caries in primary and young permanent teeth; prevention and treatment of periodontal disease; management of tooth developmental and mineralization disturbances; prevention and treatment of oral conditions in children with chronic diseases/developmental disturbances/obesity; diagnosis, prevention and treatment of dental erosion and tooth wear; treatment of traumatic injuries in primary and young permanent teeth and cost-effectiveness of these interventions. Abstracts and full text reviews were assessed independently by two reviewers and any differences were solved by consensus. AMSTAR was used to assess the risk of bias of each included systematic review. Reviews judged as having a low or moderate risk of bias were used to formulate existing knowledge and knowledge gaps. RESULTS: Out of 81 systematic reviews meeting the inclusion criteria, 38 were judged to have a low or moderate risk of bias. Half of them concerned caries prevention. The quality of evidence was high for a caries-preventive effect of daily use of fluoride toothpaste and moderate for fissure sealing with resin-based materials. For the rest the quality of evidence for the effects of interventions was low or very low. CONCLUSION: There is an urgent need for primary clinical research of good quality in most clinically-relevant domains in pediatric dentistry

Purpose: To describe 0–16-year-old children with disabilities receiving paediatric specialist dental care from a biopsychosocial perspective, with focus on relationship between oral health, medical diagnosis, and functioning. Method: A questionnaire with an International Classification of Functioning, Disability and Health – Children and Youth version (ICF-CY) Checklist for Oral Health was completed using structured interview, direct observation, and information from dental records. Descriptive data analysis was performed together with principle component analysis to calculate factors of functioning used in cluster analysis in order to present functioning profiles. Results: Ninety-nine children with at least one major medical diagnosis were included. Twenty had previous caries experience. Two factors of functioning were calculated, labelled “Physical ability” and “Intellectual ability, communication, and behaviour”. Based on functioning profiles three clusters were determined. There were no statistically significant differences in caries experience between medical diagnoses or clusters. Conclusion: It was possible to identify profiles of functioning in children with disabilities receiving specialist dental care. Despite complex disabilities, the children had good oral health. Neither medical diagnosis nor functioning was found to have a clear relationship with oral health. To understand the environmental context leading to high-quality oral health, further studies of dental management in relation to medical and oral diagnoses and child functioning are needed.

Local anesthesia, especially palatal injection, is often associated with fear and anxiety. The aim was to compare the sensation of pain when using palatal block technique with computerized injection technique (CIT), to conventional infiltration technique with traditional syringe in surgical procedures involving the palate. Patients referred for bilateral minor maxillary surgical treatments were randomized for traditional infiltration anesthesia on one side and palatal block anesthesia with CIT on the other side. AMSA and P-ASA approaches were used with CIT. The sensation of pain was scored by the VAS scale. Twenty-eight patients were included in the study, where of 17 (61%) were girls. The median age was 14.8 yrs. (12.6 - 17.8). Bilateral exposure of palatal impacted canines was the most common treatment. The injection pain was significantly lower, (p = 0.009), when using the CIT injection compared to conventional injection. However, with time-consuming surgery, additional CIT analgesic solution had to be injected in the buccal gingiva when suturing, in one fourth of the cases. Patients sedated with nitrous oxide seemed to benefit less from CIT. Computerized injection techniques, including P-ASA and AMSA approaches, reduces the sensation of pain when carrying out less time-consuming palatal dental surgery, especially in non-sedated teenagers.

OBJECTIVES: The aim of the present survey was to study the association between dental caries and body mass index (BMI) in Swedish preschool children (born in 1999). METHODS: A population-based and cross-sectional study design was used comprising all 920 5-year-old children in a defined area in and around the city of Lund. Anthropometric measures for the calculation of BMI were retrieved for each child from recordings at Child Health Care Centers (CHC). The occurrence of caries and fillings in the primary dentition, defined as deft (decayed, extracted, or filled primary teeth) and dt (decayed primary teeth), was collected from the children's dental records. RESULTS: The mean BMI was 16.1 (no differences between boys and girls). About 19.2% were overweight, of which 5.1% were obese. Overweight or obese children did not have higher deft or dt than others. However, children with low BMI (below -1 SD of national mean values for Swedish 5-year-olds) had statistically significantly higher deft and dt than children with normal BMI. CONCLUSIONS: Children with low BMI may be at risk of caries development. Low BMI may be associated with eating habits endangering dental health.

Although preterm birth is associated with an increased risk of medical problems and impairments, there is limited knowledge of how this affects oral health. It was hypothesized that when 10-12 yr of age, children who were preterm at birth would present with a higher prevalence of molar-incisor hypomineralization (MIH), more dental plaque, and a higher degree of gingival inflammation than full-term control children. Eighty-two preterm children, born between 24 and 32 wk of gestation, and 82 control children, born between 37 and 43 wk of gestation, were clinically examined for developmental defects in enamel, MIH, dental plaque, and gingival health. In addition, behaviour management problems were evaluated. Information on any aetiological factors with a potential influence on MIH and oral health was collected via questionnaires. Molar-incisor hypomineralization was more common in preterm children than in controls (38% vs. 16%), as were enamel developmental defects (69.5% vs. 51%). Low gestational age and low birth weight increased the risk of MIH. Preterm children had more plaque, a higher degree of gingival inflammation, and more behaviour-management problems than controls. In conclusion, oral health problems were more common in preterm children than in control children.

BACKGROUND: An enhanced frequency of cognitive and behavioural disturbances has been reported in preterm children. It is not known if this affects their perceptions of or behaviour in the dental care situation. HYPOTHESIS: The hypotheses were that preterm (PT) children aged 12-14 years more often exhibit dental fear and anxiety (DFA) than full-term controls (C), while no differences were expected regarding oral health behaviour. METHODS: One hundred and nine PT and 108 C children took part in the present questionnaire study. DFA was assessed using the Children's Fear Survey Schedule - Dental Subscale (CFSS-DS). In addition the questionnaire covered items including satisfaction with received dental care, oral health behaviour and medical health. RESULTS: The children's CFSS-DS scores revealed no differences between the PT and C groups. Regarding oral health behaviour there were no differences, except that PT children more often used dental floss and extra fluoride supplements. PT children reported more medical health problems than C children. CONCLUSIONS: Preterm (PT) children 12- to 14-years-old, as well as C of same age group, seem to be satisfied with their dental care and display low prevalence of DFA. Still, a higher frequency of medical health problems in the PT children suggests that these children should be regarded as potential risk patients for oral health problems.

BACKGROUND: Enamel hypoplasia is a developmental disturbance during enamel formation, defined as a macroscopic defect in the enamel, with a reduction of the enamel thickness with rounded, smooth borders. Information on the microstructural level is still limited, therefore further studies are of importance to better understand the mechanisms behind enamel hypoplasia. AIM: To study enamel hypoplasia in primary teeth by means of polarized light microscopy and scanning electron microscopy. METHODS: Nineteen primary teeth with enamel hypoplasia were examined in a polarized light microscope and in a scanning electron microscope. RESULTS: The cervical and incisal borders of the enamel hypoplasia had a rounded appearance, as the prisms in the rounded cervical area of the hypoplasia were bent. The rounded borders had a normal surface structure whereas the base of the defects appeared rough and porous. CONCLUSIONS: Morphological findings in this study indicate that the aetiological factor has a short duration and affects only certain ameloblasts. The bottom of the enamel hypoplasia is porous and constitutes possible pathways for bacteria into the dentin.

Background. Paediatric dentistry in Sweden has been surveyed four times over the past 25 years. During this period postgraduate training, dental health, and the organization of child dental care have changed considerably. Aim. To investigate services provided by specialists in paediatric dentistry in Sweden in 2008, and to compare with data from previous surveys. Design. The same questionnaire was sent to all 30 specialist paediatric dental clinics in Sweden that had been used in previous surveys. Comparisons were made with data from 1983, 1989, 1996 and 2003. Results. Despite an unchanged number of specialists (N = 81 in 2008), the number of referrals had increased by 16% since 2003 and by almost 50% since 1983. There was greater variation in reasons for referrals. The main reason was still dental anxiety/behaviour management problems in combination with dental treatment needs (27%), followed by medical conditions/disability (18%), and high caries activity (15%). The use of different techniques for conscious sedation as well as general anaesthesia had also increased. Conclusions. The referrals to paediatric dentistry continue to increase, leading to a heavy work load for the same number of specialists. Thus, the need for more paediatric dentists remains.

Ehlers-Danlos syndrome (EDS) is a rare hereditary condition affecting connective tissues and dental hard tissues. HYPOTHESES: Primary enamel and dentine from EDS patients were expected to differ from those of healthy subjects regarding morphology and chemical composition. DESIGN: Forty-seven exfoliated primary teeth from 25 patients with EDS were investigated. Morphology was studied using a polarized light microscope, scanning electron microscope, and X-ray microanalysis. Comparisons were made with 36 primary teeth from 36 healthy patients. RESULTS: Morphological analysis of enamel in EDS teeth showed a high frequency of postnatally hypomineralized enamel and postnatally located incremental lines, whereas dentine was normal in all patients. Chemical analysis could not reveal any differences between EDS and control patients except for lower content of C and a higher Ca/P ratio in the enamel in the EDS teeth, indicating porous enamel. Regarding dentine, EDS teeth had a lower content of C, and a higher content of Ca, P, and O. Ratios for Ca/C and Ca/O were also higher compared with controls. CONCLUSIONS: There are several aberrations of booth enamel and dentine in primary teeth from patients with EDS. These could explain the occurrence of both more dental caries and tooth fractures in patients with EDS.

Introduction A high frequency of cognitive and behavioural disturbances has been reported in preterm children. It is not known if this affects the children’s apperceptions or behaviours during dental treatment. The aim was therefore to investigate dental behavioural management problems (BMP) and dental anxiety (DA) in preterm children from age 3-14, and to compare with matched controls. Materials and Methods 187 preterm children (23-32 weeks of gestation), born 1994-96 were followed regarding BMP and DA. Comparisons were made with matched full-term controls. Data on BMP were collected from dental records for the ages 3 and 6 yrs. During the school years, parents were interviewed twice regarding BMP in their children. Two periods of time were covered; preschool period, and early school years. Finally, at 12-14 yrs the children filled out the CFSS-DS scale, measuring DA. Results During pre-school years pre-term children showed significantly more BMP at various kinds of dental treatments (32% vs. 15%; p<0.001). This was confirmed in the first interviews of the parents (20%vs. 10%; p=0.028). At the second interviews, covering early school years, no differences were found between the groups. This was also verified by the children’s scorings on CFSS-DS at age 12-14 where no differences in mean scores were revealed. Conclusion Children born preterm seem to have a high prevalence of BMP during preschool years. But this difference decreases with increasing age, possibly reflecting a catch-up. At school years and early adolescence no differences were seen between the groups regarding BMP or DA.
