Evaluation of the 1-year outcome of root canal treatments in dental faculty of Kashan University of medical science in 1397

Endodontic treatment is an important part of dentistry. This study aimed to evaluate the quality of root canal treatment performed by dental students at the faculty of dentistry of Kashan University of Medical Sciences.

In the present cross-sectional study 182 patients with a history of root canal treatment performed by dental students in the past year entered, and radiographs of the treated tooth and palpation test was evaluated. In this study, radiographs were evaluated by three observers: To evaluate the radiographs, PAI was used. Based upon that score 1 and 2 is healed, score 3 is uncertain and score 4 and 5 is unhealed. The Cohenchr('39')s kappa coefficient was used to assess agreement between observers.

In our study, 63% of patients were healed, 16% of patients were in uncertain range, and 21% of patients did not recover. There was a meaningful agreement in comparison of the results evaluated by the observers including: an endodontist, a radiologist and a general dentist with the palpation test (P<0.005). Also, there was a meaningful agreement in the scoring by the observers.

The quality of root canal treatment performed by dental students of dental school of Kashan University of Medical Sciences was in favorable range.
