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 co...

O objetivo deste estudo foi avaliar variação de volume, porcentagem áreas não instrumentadas e debris após o preparo canais longo ovais com sistema WaveOne® Gold (WOG) duas técnicas: uso cada instrumento dos (single-file - SF) todas as limas do modo sequencial (multiple-file MF). Foram selecionados 50 incisivos inferiores humanos, distribuídos em cinco grupos (n = 10). Após verificação da dimen...
