“…The perforations in our study occurred much more frequently in the blocks with 20% curvature than in the blocks with 10% curvature (7% and 0%, respectively). A similar result was reported in a study by Kfir et al [12], where perforation occurred in 7% of cases undergoing endodontic treatment performed by students.…”

Introduction: Step-back technique is a basic method used for root canal preparation. In dental school curricula, this technique is taught in a preclinical environment, and it is regarded as safe and technically easy to perform, usually with low-risk of complications. Objectives: The study aims to determine the incidence of different types of procedural errors during root canal preparation by second-year dental students using step-back technique performed on training blocks with 10% and 20% curvature. Material and methods: Study material consisted of 160 endodontic training blocks, which were prepared manually by eighty second-year dental students using step-back technique. The blocks were assessed by two teachers who specialized in conservative dentistry and endodontics. The occurrence of the following errors was evaluated: working length loss, improper debridement, alteration of original root canal shape, apical over-instrumentation, instrument separation, root canal blockage with dentine chips, apical transportation or perforation in root canal wall, and ledge formation within root canal wall. Results: Percentage of error-free blocks with 10% curvature was significantly higher than the percentage of errorfree blocks with 20% curvature (34% and 4%, respectively). Improper debridement was the most frequently observed error in both groups (42% and 94%, respectively). Conclusions: Our findings indicate a gap in the correct method of imparting knowledge to dental students regarding root canal preparation techniques. This disparity can be used constructively to create better training programs and more effective modules for dental students to minimize their margin of error.

A root perforation is a mechanical or pathological communication formed between the supporting periodontal apparatus of the tooth and the root canal system. Three broad categories of etiological factors exist and these are procedural mishaps, resorption and caries. The diagnosis, management and repair of root perforations require skill and creative thinking. Unfortunately, much of what has been written on the subject of root perforation repair is unsubstantiated and empirical in nature and contributes little to evidence‐based support for any specific repair procedure. However, perforation repair frequently provides a very attractive and frequently successful alternative to extraction of the involved tooth. In recent years, the procedure has become more predictable owing to the development of new materials, techniques and procedures.

Comparison of procedural errors resulting during root canal preparations completed by junior dental students in patients using an ‘8-step method’ versus ‘serial step-back technique’

Abstract: The new '8-step method' resulted in fewer procedural errors than the traditional 'serial step-back technique' when junior students prepared root canals in patients.
