First Experience of an Undergraduate Dental Student with a Reciprocating System in Simulated Root Canals—A Pilot Study

Rotary instrumentation has been proposed in undergraduate teaching. The aim of this study was to evaluate student’s performance, through the obturation quality and treatment time, a sequential range L-simulated root canals. A senior dental student sequentially prepared randomly numbered canals from 1 40, with WaveOne Gold glider primary file, according manufacturer instructions. gutta-percha cone matched finishing instrument epoxy resin-based sealer (AH Plus) selected for obturation. Three independent observers evaluated both density length. Active, total times were also measured. Statistical analysis obtained by Mann–Whitney Kruskal–Wallis tests significance level p < 0.05. number adequate length 87.5% Both active instrumentation, as well times, reduced significantly increased (p ˂ 0.05). use an inexperienced operator provided most curved simulated working time short learning curve.
