Sammanfattning

Introduction: The long-term survival of endodontically treated teeth is an issue of high priority focus in modern restorative dentistry. In available literature, survival is generally high and comparable with implants. For more compromised teeth treated in a specialist clinic, survival-rate may be lower. This retrospective study aimed to investigate the 10-year survival rate of teeth treated in a public endodontic specialist clinic. Methods: From a database of 15,000 examined teeth, 420 teeth in 330 patients were randomly selected and included. Available potential preoperative, intraoperative, and postoperative prognotic factors were registered. Ten-year tooth survival was recorded by scrutinizing records and by contacting referring dentists and patients. Results: The overall Kaplan-Meier estimated 10-year survival rate was 81.5% (95% confidence interval [Cl], 76.7%-85.5%). Placement of a crown, adjusted hazard ratio 0.27 (95% Cl, 0.12 0.61), P = .0016, and age-adjusted hazard ratio 1.31 per 10 years (95% Cl, 1.11-1.55), P = .0012, were significant independent predictors for estimated survival rate. Seventy-three teeth (17.4%) in 69 patients were extracted during the 10-year follow-up period. The declared reason for extraction was related to endodontic diagnoses in only 5 of the cases (6.8%). Conclusions: Approximately 80% of the teeth treated at this specialist clinic in endodontics survived at least for 10 years. Teeth in young persons and teeth restored with a crown postoperatively survived significantly better. To further explore the importance of the postoperative restoration in endodontically treated teeth, randomized controlled trials need be carried out. BOTT PV, 1994, JOURNAL OF ENDODONTICS, V20, P93
