The main objective of endodontic treatment is to prevent or treat apical periodontitis. Treatment outcome of root canal treatment differs significantly between specialist and general dentists.
The aim of this study was to evaluate the outcome of root canal treatment provided by postgraduate students of the department of Endodontics of Library, Riga Stradins University. The study involved ninety-eight teeth (71 patient) who were clinically and radiographically examined. Periapical index (PAI) was used to evaluate apical periodontitis (AP) radiographically. PAI score dichotomize success and failure, PAI<3 success, but PAI ≥ 3 failure. Based on clinical and radiographic evaluation outcomes was defined as healed, healing and disease. For statical analysis was used SPSS software. Outcome for primary teeth in initial endodontic treatment group 72% teeth is healed, 14% is healing. Among the 48 retreated teeth 85% is healed and 12% is healing. An association was found between success rate and preoperative signs or symptoms. In this study postgraduate students prove to show good outcome rate both in primary endodontic treatment groupe and retreatment group. Outcome in this study were similar to those previosly reported. Limitation of the study is the small sample size and problematic recall rate, larger sample size is needed to assess outcome predictors more precisely.
