The study aimed to investigate the survival and success rates of primary non-surgical endodontic therapy. The results showed that after 10, 20, 30, and 37 years of follow-up, the cumulative survival rates of the treated teeth were 97%, 81%, 76%, and 68%, respectively, while the corresponding values for endodontic success were 93%, 85%, 81%, and 81%. Deep periodontal pockets (> 6 mm), pre-operative apical radiolucency, and lack of occlusal protection were identified as significant prognostic factors associated with tooth extraction.
ObjectivesThe aims of the present longitudinal retrospective observational case series study were to investigate the survival and success rates of primary non-surgical endodontic therapy.Materials and methodsPatients with at least one endodontically treated tooth (ETT), with 5 years of follow-up and in compliance with the recall programme of at least 1 time per year in a private practice setting, were recruited. Kaplan-Meier survival analyses were performed considering (a) tooth extraction/survival and (b) endodontic success as the outcome variables. A regression analysis was performed to evaluate prognostic factors associated with tooth survival.ResultsThree hundred twelve patients and 598 teeth were included. The cumulative survival rates showed 97%, 81%, 76% and 68% after 10, 20, 30 and 37 years, respectively. The corresponding values for endodontic success were 93%, 85%, 81% and 81%, respectively.ConclusionsThe study demonstrated high longevity in symptomless function as well as high success rates of ETT. The most significant prognostic factors associated with tooth extraction were the presence of deep (> 6 mm) periodontal pockets, the presence of pre-operative apical radiolucency and the lack of occlusal protection (no use of a night guard).
