Objectives: This study aimed to compare the transportation of the mesiobuccal canal of maxillary molars following root canal preparation with HyFlex CM (HCM) and Edge Taper Platinum (ETP) rotary systems and stainless steel (SS) hand files using cone-beam ... see more

Three-dimensional Computed Tomography (CT) is used to analyze the topography of the root canal anatomy in order to make a decision in choosing root canal preparation method. There is a method that make extracted teeth transparent maintaining its anatomica... see more

The aim of the present study was to evaluate and quantify the presence of hard-tissue debris inside curved canals, after root canal preparation with a single-fi le reciprocating system, with the aid of microcomputed tomography (micro-CT). Twenty-four mesi... see more

OBJECTIVE: This in vitro study aimed to evaluate preparation time, wear, transportation, and centering ability of two manual instruments, namely Flexofile and Prodesign® M, in curved root canal preparation.METHODS: Forty mesiobuccal and mesiolingual canal... see more

Objective: To evaluate, by diaphanization, the cleaning ability three different instruments on walls of flattened root canals.Methods: Thirty lower incisors, which had their root canals filled with India ink after coronal access and determinatio... see more

Aim: The aim of this study was to evaluate the presence of filling material in oval root canals after endodontic retreatment performed by different techniques, considering the area (mm2), location and root third using computed microtomography (µ-CT). Meth... see more

Introduction: Although rotary instrumentation has been widely studied in permanent dentition, it is a rather new field of study concerning primary teeth. Purpose: We aimed to evaluate apical displacement and time needed for instrumentation of root canals ... see more

The purpose of this study was to evaluate by diaphanization the cleaning ability of walls of flattened root canals prepared with three different instruments. Thirty lower incisors, which had their root canals filled with India ink after coronal access and... see more

Purpose: To evaluate the preparation of root canals performed by undergraduate students using manual and automated devices, based on the amount of dentin removed from the canal walls, the time required for preparation, and students’ opinions.Methods: Mesi... see more
