This study aimed to evaluate, in vitro, the cutting efficiency and time spent for instrumentation of three different heat-treated reciprocating systems simulated straight canals. Forty-five acrylic blocks with a root canal 21 millimeters length were initially weighed (P1). After weighing divided into groups (n = 15) each group prepared following systems: ProDesign R 25.06 (Bassi/Easy, Belo Hori...

Aim: The aim of the study was to evaluate cleaning mandibular incisors with WaveOne Gold® (WO) under different preparation techniques. Methods: A total 210 human were selected and divided into seven groups (n = 30), prepared by WO single-files (Small 20/.07 – WOS; Primary 25/.07 WOP; Medium 35/.06 WOM; or Large 45/.05 - WOL) sequential-file techniques (WOS WOS WOL). Further subdivision made acc...
