Introduction. The aim of this study is to determine the most common endodontically treated tooth and the most common error produced during treatment and to note the association of particular errors with particular teeth. Material and Methods. Periapical radiographs were taken of all the included teeth and were stored and assessed using DIGORA Optime. Teeth in each group were evaluated for presence or absence of procedural errors (i.e., overfill, underfill, ledge formation, perforations, apical transportation, and/or instrument separation) and the most frequent tooth to undergo endodontic treatment was also noted. Results. A total of 1748 root canal treated teeth were assessed, out of which 574 (32.8%) contained a procedural error. Out of these 397 (22.7%) were overfilled, 155 (8.9%) were underfilled, 16 (0.9%) had instrument separation, and 7 (0.4%) had apical transportation. The most frequently treated tooth was right permanent mandibular first molar (11.3%). The least commonly treated teeth were the permanent mandibular third molars (0.1%). Conclusion. Practitioners should show greater care to maintain accuracy of the working length throughout the procedure, as errors in length accounted for the vast majority of errors and special care should be taken when working on molars.
引言。本研究的目的是确定接受牙髓治疗最常见的牙齿、治疗过程中最常见的失误，并记录特定失误与特定牙齿的关联。材料与方法。对所有纳入研究的牙齿拍摄根尖片，并使用DIGORA Optime进行存储和评估。评估每组牙齿是否存在操作失误（即超充、欠充、台阶形成、穿孔、根尖移位和/或器械分离），同时记录接受牙髓治疗最常见的牙齿。结果。共评估了1748颗根管治疗后的牙齿，其中574颗（32.8%）存在操作失误。其中，397颗（22.7%）超充，155颗（8.9%）欠充，16颗（0.9%）器械分离，7颗（0.4%）根尖移位。接受治疗最频繁的牙齿是右侧下颌第一恒磨牙（11.3%）。治疗最少的牙齿是下颌第三恒磨牙（0.1%）。结论。从业者在整个治疗过程中应更加注意保持工作长度的准确性，因为长度失误占绝大多数失误，并且在治疗磨牙时应格外小心。
