[ 1 ] - Effect of different torques on dentinal crack formation following canal preparation using neoniti rotary system
Introduction: The aim of this study was to determine the incidence of dentinal cracks in the mesial root of maxillary molar during canal preparation using Neoniti system in different torque settings. Materials &Methods: In this in-vitro study, 60 maxillary molars extracted for various reasons were selected. The teeth were divided into 4 groups: one group(n=15) without preparation was con...
[ 2 ] - A cone-beam computed tomography study of apical and mental foramen’s location in mandibular premolars
Introduction: Knowledge of the internal anatomy of the tooth, apical foramen (AF) and mental foramen (MF) is considered a basic prerequisite before root canal surgical and non-surgical treatments. The aim this study is evaluation the distance and situation of AF & MF to anatomic apex of mandibular premolar. Materials & Methods: In this cross-sectional study, CBCT images of mandibular p...
[ 3 ] - Evaluation of the accuracy of two apex locators in endodontic treatment and retreatments: an ex vivo study
Introduction: Working length determination is important in successful endodontic treatment and retreatment.This study evaluated the accuracy of two electronic apex locators Root ZX and Raypex®6 (EALs) in determining the electronic working length (EWL) of the root canals in endodontic treatment and retreatment. Materials and Methods: Access cavities were prepared on forty extracted, singl...
[ 4 ] - A comparative evaluation of apical microleakage of MTA fillapex and AH26 sealers in the presence of blood in the canal space of the teeth
Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...
