    Characteristics and impact of pain from root-filled teeth: A practice-based cross-sectional study comparing painful teeth with and without signs of inflammatory dental disease2024In: The Journal of Oral & Facial Pain and Headache, ISSN 2333-0384 , E-ISSN 2333-0376 , Vol. 38, no 1, p. 64-76Article in journal (Refereed)
    Abstract [en]

    To compare pain characteristics, impact of pain and characteristics of patients withpainful root-filled teeth with and without signs of inflammatory dental disease. Thiscross-sectional study was performed in the Public Dental Health services, RegionÖrebro County, Sweden. Adult patients with ≥1 root-filled tooth identified at theirregular check-up were included and assigned to one of two groups; those with ≥1sign of inflammatory dental disease (DD+) and those without any such sign (DD−).Patients/teeth were compared regarding pain characteristics (intensity, frequency,duration, quality and provoking factors), impact of pain (medication intake, impacton life) and patient characteristics as background factors (general health, other bodilyand orofacial pain). Statistics included descriptive data (frequency tables) and groupcomparisons (Chi-square, Fisher’s Exact and Mann-Whitney U-tests). The DD+ groupincluded 27 participants (30 teeth) and the DD− group 22 participants (23 teeth).On average, pain intensity was mild, the frequency most often recurrent, and theimpact was low. Average pain duration since onset exceeded 2 years in both groups.The only observed between-group differences were average pain intensity; 3.1 (0–10Numerical Rating Scale (NRS)) in DD− group compared to 1.6 for DD+ (p = 0.030),and tenderness to apical palpation; only reported in the DD+ group. The similaritiesin clinical presentation between the two groups underscore the difficulties in correctlydistinguishing between pain of odontogenic and non-odontogenic origin in root-filledteeth with a standard clinical investigation. Additional diagnostic methods need to beinvestigated for their ability to differentiate between tooth pain or discomfort of differentorigins

    Interventions in root‐filled teeth identified in general dental practice: A 6‐year longitudinal observational study2024In: International Endodontic Journal, ISSN 0143-2885, E-ISSN 1365-2591Article in journal (Refereed)
    Abstract [en]

    Aim: To  investigate  what  happens  to  cross-  sectionally  identified  root-  filled  teeth  over  a  6-  year  period,  regardless  of  the  time  that  elapsed  since  primary  root  canal  treatment, in a cohort of adult patients regularly attending a Public Dental Service. A secondary aim was to investigate how the cumulative events affecting root- filled teeth  over  the  same  time  were  associated  with  variables  obtained  from  a  baseline  examination.Methodology: Adult patients with ≥1 previously root- filled tooth and regularly at-tending the Public Dental Service in Örebro County were enrolled for study partici-pation in 2015. General dental practitioners examined all identified root- filled teeth in this cohort at baseline using a standardized protocol and were also responsible for further decision- making and treatments. After six years, information on events of the root- filled teeth was collected from dental records. The highest rating (most invasive treatment) on a 5- point ordinal scale was used in the analyses. Regression analyses with stepwise selection were performed for associations between patient-  and tooth- related factors and events.Results: A total of 445 patients with 1007 root- filled teeth were followed the entire observation time. Twenty (2.0%) of the root- filled teeth had endodontic retreatment and  150  (14.9%)  were  extracted  over  six  years.  Among  teeth  with  periapical  radio-lucency  or  pain,  the  majority  did  not  undergo  retreatment  or  extraction;  however,  the multivariate analysis demonstrated that retreatment or extraction was associated with baseline recordings of teeth with periapical radiolucency (p< .0001),  tenderness to percussion (p<   .0001), and poor coronal restoration (p< .0001).Conclusions: This  study  corroborates  the  notion  that  in  general  dentistry,  root-  filled teeth with radiological signs of apical disease often remain untreated over time. Furthermore,  it  also  reveals  that  root-  filled  teeth  presenting  with  mild  pain  do  not  necessarily  receive  any  intervention.  However,  teeth  with  baseline  signs  of  apical  periodontitis,  pain,  or  inadequate  coronal  restoration  were  more  likely  to  have  re-ceived intervention during the six- year period.
