- BACKGROUND: In conjunction with post placement in root-filled teeth with periapical healthy conditions, root canal retreatment may be performed to improve the seal of the root canal. Whether root canal retreatment for technical reasons (retreatments in teeth without apical periodontitis (AP)) results in lower frequency of AP is unknown.OBJECTIVE: To examine whether there is a difference in frequency of AP between roots with root canals retreated for technical reasons, and roots with root canals not retreated before post placement, with a minimum follow-up of 5 years. Also, to examine changes in root filling quality following root canal retreatment for technical reasons.METHODS: This retrospective study included radiographs of 441 root-filled roots without periapical radiolucencies at baseline, scheduled for post and core treatment. Follow-up data for a minimum of 5 years were available for 305 roots (loss to follow-up 30.8%), 46 of which were retreated for technical reasons. Two calibrated observers assessed root filling sealing quality and length, respectively, and periapical status according to the Periapical Index. The main outcome of the study, AP, was used as the dependent variable and all analyses were performed at root level.RESULTS: The overall frequency of AP at follow-up was 13.8%. The difference in frequency of AP between retreated (4.3%) and nonretreated (15.4%) root canals was not statistically significant, p = .061. Analyses including only roots with preoperatively inadequate root filling quality showed a statistically significant difference (p = .017) between the two treatment groups (2.4% vs. 22.9%).CONCLUSIONS: Root canal retreatment for technical reasons before post and core placement significantly reduces the frequency of AP in roots with inadequate root filling quality.

- 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 attending the Public Dental Service in & Ouml;rebro County were enrolled for study participation 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 radiolucency 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 received intervention during the six-year period.

- To compare pain characteristics, impact of pain and characteristics of patients with painful root-filled teeth with and without signs of inflammatory dental disease. This cross-sectional study was performed in the Public Dental Health services, Region orebro County, Sweden. Adult patients with >= 1 root-filled tooth identified at their regular check -up were included and assigned to one of two groups; those with >= 1 sign 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, impact on life) and patient characteristics as background factors (general health, other bodily and orofacial pain). Statistics included descriptive data (frequency tables) and group comparisons (Chi-square, Fisher's Exact and Mann-Whitney U-tests). The DD+ group included 27 participants (30 teeth) and the DD- group 22 participants (23 teeth). On average, pain intensity was mild, the frequency most often recurrent, and the impact 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 (0-10 Numerical 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 similarities in clinical presentation between the two groups underscore the difficulties in correctly distinguishing between pain of odontogenic and non-odontogenic origin in root-filled teeth with a standard clinical investigation. Additional diagnostic methods need to be investigated for their ability to differentiate between tooth pain or discomfort of different origins.
