Objectives To investigate alveolar bone loss (ABL), which is an indicator of periodontitis, and to identify risk factors for ABL in an older population between 2008 and 2018. Methods This longitudinal study used data from a questionnaire survey and a clinical examination administered on two occasions ten years apart to 273 individuals who were 65 years and 75 years in 2008. Results The mean number of teeth decreased significantly over the ten-year study period, while the proportion of individuals with calculus and moderate ABL visible on radiographs increased. For both ages, the number of teeth decreased by a mean of 2 teeth. The proportions of participants reporting poor general health, daily medication, xerostomia, living singly, visiting dental care irregularly and being in need of extra support in their homes all increased over the observation period. Conclusions Despite an increased progression of moderate alveolar bone loss, a fairly good dentition and chewing capacity was retained in this older population. However, the individual's age and fragility are important indicators that need to be considered when planning oral health care and the availability of dental care.

OBJECTIVES: To investigate the prevalence of dental caries and to identify risk factors for dental caries in an elderly population between 2008 and 2018.

METHODS: This longitudinal study used data from a questionnaire survey and a clinical examination administered on two occasions 10 years apart to 273 individuals who were 65 and 75 years of age in 2008. The variables included were prevalence of dental caries as well as socioeconomic and socio-behavioural factors.

RESULTS: The number of teeth decreased in both age groups by a mean of 2 over the 10-year study period, but the prevalence of dental caries remained stable. Approximately, a quarter of the participants had caries lesions. Toothbrushing once a day or less was the factor most strongly correlated with dental caries lesions (OR: 3.82, 95% CI: 1.68-8.66, p = 0.001), followed by need for homecare (OR: 3.50, 95% CI: 1.55-7.93, p = 0.003) and interproximal cleaning less than once a day (OR: 2.65, 95% CI: 1.36-5.19, p = 0.004).

CONCLUSIONS: This longitudinal study revealed no increase in the prevalence of dental caries lesions, indicating that good oral health can be preserved among elderly people. The highest risk for dental caries lesions was among participants with inadequate oral hygiene routines (toothbrushing once a day or less and seldom using interproximal devices) and in need of help in daily living, emphasizing the importance of oral hygiene and collaboration between dental services and community-based health care.

INTRODUCTION: Oral health is part of general health, and oral diseases share risk factors with several non-communicable diseases. The World Dental Federation (FDI) has published a theoretical framework illustrating the complex interactions between the core elements of oral health (CEOHs): driving determinants, moderating factors, and general health and well-being. However, the framework does not specify which self-reported or clinical measurements to be included in the CEOHs.

OBJECTIVES: To explore oral health measurements relevant for a general adult population to be included in the CEOHs in the FDI's theoretical framework of oral health.

MATERIALS AND METHODS: A psychometric study was performed, using cross-sectional data from Sweden (N = 630, 54% women, mean age 49.7 years). The data set initially consisted of 186 self-reported and clinical measurements. To identify suitable measurements, the selection was discussed in different settings, including both experts and patients. Principal component analyses (PCAs) were performed to explore, reduce and evaluate measurements to be included in the three CEOHs. Internal consistency was estimated by Cronbach's Alpha.

RESULTS: The validation process yielded 13 measurements (four clinical, nine self-reported) in concordance with the CEOHs. PCAs confirmed robust validity regarding the construction, predicting 60.85% of variance, representing psychosocial function (number of measurements = 5), disease and condition status (number of measurements = 4), and physiological function (number of measurements = 4). Cronbach's Alpha indicated good to sufficient internal consistency for each component in the constructs (α = 0.88, 0.68, 0.61, respectively).

CONCLUSION: In a Swedish general adult population, 13 self-reported and clinical measurements can be relevant to include to operationalise CEOHs in the FDI's theoretical framework.

AimTo assess trends over 40years regarding prevalence and severity of periodontitis in a Swedish adult population. Materials and methodsCross-sectional examinations using the same clinical protocol have been repeated every 10years (1973-2013) in a Swedish city with focus on periodontal disease in adults. Periodontal recordings included all teeth, excluding 3rd molars. Periodontal disease experience was classified (no/minor, moderate and severe). ResultsThe no/minor group increased from 43% in 1983 to 60% in 2013. There was a non-significant trend for a decrease of the severe group. Over the 40-year period, the number of teeth increased significantly and at the examination 2013, the severe group accounted for this increase. More than 60% of the study population in 2013 had no periodontal pockets (PD) 6mm. The number of PD 4mm and 6mm were unaltered between 2003 and 2013 in all age groups, except for the 20-year old individuals. This group showed a statistically significant increase of 4mm PD. ConclusionsThe periodontal health has improved in the population over the 40 years. The number of teeth increased significantly in the population, and in 2013, this increase occurred entirely in the severe group. Finally, there was a trend toward diminished prevalence of severe periodontitis.

Repeated epidemiological studies have been performed in the city of Jönköping, Sweden, every 10 years since 1973. The studies were initiated in order to describe the changes in oral health in the population. Basic preventive dental care and supplementary programs were extensively performed in the population, especially among children and adolescents. In this population, the percentage of individuals with sound teeth (no caries or restorations) continuously increased each decade. The main finding regarding periodontitis is the significant increase in individuals having no or minimal periodontitis experience. In 2013, 20–60-year-olds had nearly complete dentitions (28 teeth), and the individuals in age groups 70 and 80 years had a mean number of teeth of 23 and 21, respectively. Edentulous individuals having complete dentures in the age groups 40–70 years decreased from approximately every sixth individual in 1973 to none in 2013. The continuous improvement in oral health and the reduced need for restorative treatment will have an impact on dental health-care and dental delivery systems in the near future.

Aim: The purpose of this radiographic study was to evaluate the prevalence of intrabony defects and to study the correlation between these defects and clinical variables in a Swedish adult population. Another aim was to study the combined relationship of intrabony defects and furcation involvement with clinical variable. Materials and methods: The present study was performed using bitewing and apical radiographs from 329 subjects. The clinical and radiographic data were collected from the study that was carried out in Jonkoping 2003. Intrabony defects were measured from the bottom of the pocket to the highest point of alveolar bone crest. Furcations were considered healthy if the furcation was filled with bone up to the fornix. SPSS was used to analyze the results. Results: 2014 molars and 5898 non-molars were included in the study. The prevalence of intrabony defects was 2.2% in the whole population. Multivariate analysis showed that periodontal pockets (p <0.0001), plaque (p <0.001), age (p <0.02) and gender (p <0.03) had a significant relationship with the occurrence of intrabony defects. On the other hand, gingivitis, smoking habits and education level were not associated with intrabony defects. Multivariate analysis showed that the only variable associated with presence of intrabony defects and furcation involvement was presence of periodontal pockets (p <0.0001). Whilst, gingivitis, education level, plaque, gender, age and smoking habits were not associated with the outcome. Conclusions: Mandibular second molars were most likely to display intrabony defects, whilst mandibular incisors were the least likely to do so.

The purpose of this study was to identify the prevalence of molars with furcation involvements grades II and III in adults participating in the Jonkoping Oral Health Study 2003. The second aim was to study correlations between different variables and the presence of furcation involvement in these individuals. The present study was performed using bitewing and apical radiographs from 329 subjects. Furcations were considered healthy if the furcation was filled with bone up to the fornix. Two thousand fourteen molars fulfilled the inclusion criteria. The prevalence of molars with furcation involvements was 8.3%. Univariate analysis showed that plaque, age, and presence of periodontal pockets were significantly correlated with furcation-involved molar/s (P 0.0001). Gingivitis and education were also significantly correlated to the presence of furcation involvement (P 0.006) and (P <= 0.01), respectively. Gender had no association with presence of involvements. Multivariate analysis showed that age and presence of periodontal pockets were significantly correlated with furcation involvement (P 0.0001). Smoking was also found to be associated with furcation involvement (P 0.04). The tooth most frequently and least likely displaying furcation involvement was the maxillary first molar and the mandibular second molar, respectively. Periodontal pockets, age, and smoking were risk indicators for furcation involvement.

The aim of the this study was to present data on oral care habits and knowledge of oral health in 2013, and to compare these data with results from a series of four previous cross-sectional epidemiological studies. All these studies were carried out in the city ofionkoping, Sweden, in 1973,1983,1993, 2003, and 2o13.The 1973 study constituted a random sample of L000 individuals evenly distributed in the age groups 3, 5,10,15, 20, 30,40, 50, 6o, and 7o yea rs.The same age groups with addition of a group of 8o-year-olds were included in the 1983,1993, 2003, and 2013 studies, which comprised 1,104;1,078; 987; and 1,010 individuals, respectively. A questionnaire about dental care habits and knowledge of oral health was used. The questionnaire contained the same questions in all the five studies, although some had to be slightly modernised during the 40-year period. During the period 1973-2013, a continous increase of individuals in the age group 20-6o years were treated by the Public Dental Service amounting to about 5o%. Almost 7o% of the 70- and 80-year-olds were treated by private practitioners. In 2013,10-20% of the individuals in the age groups 30-40 years did not regularly visit neither Public Dental Service nor a private practitioner.The corresponding figures for the individuals 50-80 years old were 4-7%. Similar number of avoidance was reported in the previous studies. In the survey 2013, about 20-30% of the individuals in the age groups 20-50 felt frightened, sick, or ill at ease at the prospect of an appointment with the dentist.These findings were in agreement with the results from the surveys 1973-2003. Among the younger age groups, 10-15 years, a reduction in self-reported "ill at ease" was found in the surveys 2003 and 2013 compared to the previous surveys in this series. In 2013, the knowledge of the etiology of caries was known by about 6o% of the individuals which was similar to that reported 1973 zoo3.Twenty per cent of the individuals stated that they did not know which etiological factors that causes caries.This percentage was equivalent during the period 1973-2013. About 85% of the individuals in all age groups brushed their teeth with fluoride tooth paste at least two times a day.These frequencies have gradually increased during the 40-year period. Around 40% in the age groups 50-8o years used toothpicks regularly in 2013.This is a about 1/3-1/2 less compared to 2003. In the age groups 20-40 years 3-14% used toothpicks for proximal cleaning in 2013. In 2013, about 35% of the individuals never consumed soft drinks, in comparison with 20% in 2003. In the age groups 3-20 years about 20% were consuming soft drinks every day or several times a week, which is a reduction by half compared to 2013

The aim of this epidemiological study performed in 2013 was to analyze various clinical and radiographic data on oral health and compare the results to those of four cross-sectional studies carried out 1973-2003. In 1973,1983,1993,2003, and 2013 random samples of 1,000;1,104;1,078; 987; and 1,010 individuals, respectively, were studied.The individuals were evenly distributed in the age groups 3,5,10,15, 20,30,40,50, 60,70, and 8o years. Eighty-year-olds were not included in 1973. All subjects were inhabitants of the city of Jonkoping, Sweden. The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations, oral hygiene, calculus, periodontal status, and endodontic treatment. The frequency of edentulous individuals aged 40-70 years was 16,12, 8,1, and 0.3% in 1973,1983,1993, 2003, and 2013, respectively. No complete denture wearer younger than 80-years old was found in 2013. During the 40-year period, the mean number of teeth in the age groups 30-80 years increased. In 2013, the 60-year-olds had nearly complete dentitions. Implants were found in all age groups from 30 years of age.The total number of individuals with implants was 36 in 2013.This was higher than earlier surveys,4 in 1993, and 18 in 2003. The percentage of children and adults without caries and restorations increased during the 40-year period. It was found that the percentage of caries-free 3- and 5-year-olds were 79% and 69%, respectively, of the individuals in 2013. In the age groups 10-20 years, the percentage of caries-free individuals increased between 2003 and 2013. In 2013,43% of the 15-year-olds were completely free from caries and restorations compared to 20% in 2003. In all age groups 5-60 years, DFS was lower in 2013 compared to the earlier examinations.There was no major change in DFS between 2003 and 2013 in the age groups 70 and 80 years.The most obvious change was the decrease in number of FS over the 40 year period of time. Regarding crowned teeth the most clear changes between 1973 to 2013 were the decrease in percentage of crowned teeth in the age goups 4o and 50-year-olds.The percentage of endodontically treated teeth decreased between 1973 and 2013 in all age groups. In age groups-Jo-30-year-olds a major reduction from about 3o% to 15% in mean plaque score was seen between 1973-2003. Only a minor change in plaque score was seen during the last decade. For the age groups 40 years and older, a decrease in the percentage of surfaces with plaque was observed between 2003-2o13.The percentage of tooth sites with gingivitis was for zo years and older about 4o% in 1973. In 2013, the percentage was about15%.The frequency of sites with gingivitis was generally lower in 2013 compared with the other years:1973-1993. The percentage of individuals with probing pocket depths >4mm increased with age. Between 2003-2013 a clear reduction was seen in all age groups in frequency of individuals with probing pocket depth >4mm. Over the 40-year period an increase in the number of individuals with no marginal bone loss and a decrease in the number of subjects with moderate alveolar bone loss were seen. The continuous improvement in oral health and the reduced need of restorative treatment will seriously affect the provision of dental helath care and dental delivery system in the near future.

AimTo evaluate the clinical treatment effects of a glycine powder air-polishing or ultrasonic device on peri-implant mucositis. Materials and methodsThirty-seven patients with one implant diagnosed with peri-implant mucositis (probing depth 4mm (0.2N) and bleeding on probing (BOP) (primary outcome)) were randomly assigned to treatment with either glycine powder air-polishing (GPAP) or ultrasonic (US) debridement. Treatment was performed at baseline and at 3 and 6months. Professional supra gingival cleaning was performed at 9 and 12months. Oral hygiene instructions were reinforced at each visit. ResultsAt 12months there was a statistically significant reduction in mean plaque score, bleeding on probing and number of periodontal pockets 4mm within the treatment groups compared to baseline. The percentages of diseased sites were significantly reduced for both groups. ConclusionsTreatment with a glycine powder air-polishing or an ultrasonic device is effective in non-surgical treatment of peri-implant mucositis.
