Quality evaluation of process of root canal treatments performed on young adults in Finnish public oral health service

Abstract

Objectives: To evaluate the quality of root canal treatments performed in every-day practice on young adults. Methods: A quality index related to the treatment process was developed based on the guidelines of the European Society of Endodontology. A random computerised selection of 134 young adults (born 1966–1971) produced 125 (93%) eligible oral health documents, including information on 148 teeth that were root canal treated by 47 dentists. The process of root canal treatment was evaluated according to the original oral health documents. The technical quality of root canal fillings was assessed on postoperative periapical radiographs. Results: The overall Kappa statistics for the inter-examiner reliability of assessments was 0.63; the proportional agreement being 87%. The mean quality index was 6.2, s.d. 2.0, with none of the treatments scoring the maximum 13. On the 56 available postoperative radiographs, 52% of the fillings were optimal, showing a length within 0–3 mm from the radiological apex, no voids in the apical part nor lumen apical to the filling. Of the completed 144 root canal treatments, only 11 included some recorded follow-up information within 15 months from the termination of the treatment. Conclusions: The technical quality of the root fillings was similar to that found in previous studies. However, the quality index, paucity of pre- and post-operative radiographs, and the lack of follow-up all indicated a discrepancy between consensus guidelines and every-day practice.
