- AimThis historical prospective cohort study of the adult population of Sweden is based on data from a national registry: the primary aim was to evaluate the long-term survival of teeth after periradicular surgery. A secondary aim was to identify factors predictive of extraction within 10 years of registration of periradicular surgery. MethodologyThe cohort consisted of all individuals who had undergone periradicular surgery to treat apical periodontitis, as reported to the Swedish Social Insurance Agency (SSIA) in 2009. The cohort was followed until 31 December 2020. Subsequent registrations of extractions were collected for Kaplan-Meier survival analyses and survival tables. The patients' sex, age, dental service provider and tooth group were also retrieved from SSIA. Only one tooth per individual was included in the analyses. Multivariable regression analysis was used and p < .05 was considered statistically significant. The reporting guidelines STROBE and PROBE were followed. ResultsAfter data cleaning, and exclusion of 157 teeth, 5622 teeth/individuals remained for analysis. The mean age of the individuals at the time of the periradicular surgery was 60.5 years (range 20-97, standard deviation 13.31); 55% were women. At the end of the follow-up, that is, up to 12 years, a total of 34.1% of the teeth had been reported as extracted. The multivariate logistic regression analysis, based on follow-up data at 10 years after registration of the periradicular surgery, included 5548 teeth, of which 1461 (26.3%) had been extracted. Significant associations between the independent variables tooth group and dental care setting (both p < .001) and the dependent variable extraction were found. The highest odds ratio (OR) for extraction applied to tooth group: compared to maxillary incisors and canines, mandibular molars were at greatest risk of extraction (OR 2.429, confidence interval 1.975-2.987, p < .001). ConclusionsAfter periradicular surgery in predominantly elderly people in Sweden, approximately three-quarters of the teeth are retained over a 10-year period. The type of tooth is associated with extraction: mandibular molars are at greater risk of extraction than maxillary incisors and canines.

- Aim To (i) investigate the frequency and characteristics of pain and discomfort associated with root filled teeth in adult patients regularly attending the Public Dental Service in orebro County, Sweden; (ii) assess the association between symptoms and clinical and radiographic findings; and (iii) explore the impact of pain and discomfort from root filled teeth on daily life. Methodology Patient records of adult patients (>= 20 years) scheduled for routine check-ups in April 2015 were screened to identify individuals with root filled teeth; all patients with >= 1 root filled tooth were asked to participate. The examination comprised of clinical and radiographic examinations and questionnaires on general health, on pain symptoms from root filled teeth and on the impact of pain on daily activities. In a general estimating equation (GEE), examination findings and patient-related factors were independently analysed in relation to the outcome 'presence of pain'. Results In total, 550 patients with 1256 root filled teeth participated. Fifty-three patients (9.6%) experienced pain or discomfort from 62 (4.9%) root filled teeth. Lower age, percussion tenderness and apical tenderness were significantly associated with pain (P > 0.001 to P = 0.044). The average pain intensity was 2.1 on a (0-10) Numeric Rating Scale, and average duration was 28.4 months. The impact on daily life was low. Conclusions On average, pain associated with root filled teeth was of mild intensity, >2 years of duration and had low impact on daily life. Although the significantly associated clinical findings may indicate apical periodontitis as the most probable explanation in some teeth, the origin of pain from root filled teeth remains partly unexplained.

- © 2016 American Association of Endodontists. Introduction The aim was to assess survival in the Swedish population of teeth treated by nonsurgical root canal treatment during 2009. Methods Data from the Swedish Social Insurance Agency were analyzed by Kaplan-Meier analysis to assess cumulative tooth survival during a period of 5-6 years of all teeth that were root-filled during 2009. Results In 2009, 248,299 teeth were reported as root-filled. The average age of the patients at the time of the root filling was 55 years (range, 20-102 years). The teeth most frequently root-filled were the maxillary and mandibular first molars. During the 5- to 6-year period 25,228 of the root-filled teeth (10.2%) were reported to have been extracted; thus 223,071 teeth (89.8%) survived. Tooth survival was highest in the youngest age group (93.2%). The highest survival (93.0%) was for the mandibular premolars, and the lowest (87.5%) was for the mandibular molars. Teeth restored with indirect restorations within 6 months of the root filling had higher survival rates (93.1%) than those restored with a direct filling (89.6%). Conclusions In the adult population of Sweden, teeth that are root-filled by general practitioners under the tax-funded Swedish Social Insurance Agency have a 5- to 6-year survival rate of approximately 90%.

Ten-year follow-up on adoption of endodontic technology and clinical guidelines amongst Danish general dental practitioners
- 2018

Journal article (peer-reviewed)abstract
- Objective: The aim of this study was to re-assess the adoption of certain endodontic technology and central treatment principles of root canal treatments as advocated by guidelines presented by the European Society of Endodontology. Material and methods: The questionnaire included the same questions in 2003 and 2013. The general dental practitioners (GDPs) anonymously reported how frequent ('often', 'occasionally', and 'never') they used certain endodontic technology and adhered to central treatment principles. The statistical analyses were performed using Chi-squared test and Goodman-Kruskal's gamma-coefficient as an association measure. Results: The overall response rate of the 2013 group was 46.5% (n = 531). The frequencies of GDPs reporting often use of rubber dam, apex locator and rotary NiTi instruments were significantly higher (p < .0001) than in 2003, as well as reporting the use of composite resin for coronal sealing (p < .019). Adoption was significantly influenced by the factors gender (p = .601) and time since graduation (p = .361), and the cluster analyses revealed the neglected use of rubber dam to be associated with no established postoperative recall system. Conclusions: After 10 years, there was a higher frequency of GDPs who had adopted certain endodontic technologies. However, progress towards high-quality root canal treatment might be obstructed as the majority of GDPs avoids consistent use of rubber dam, and routinely neglects recalls for postoperative controls of their endodontic treatments.

Journal article (peer-reviewed)abstract
- 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.
