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...
متن کاملEffect of different nickel-titanium rotary files on dentinal crack formation during retreatment procedure
Background. The aim of this study was to compare the dentinal defects caused by Reciproc, TF Adaptive and ProTaper Next NiTi rotary file systems during the retreatment procedure. Methods. A total of 150 mandibular incisors with straight and single root canals were included in the present study. All the root canals were prepared up to an apical diameter 0.40 mm using stainless steel files. Thirt...
متن کاملStereomicroscopic Evaluation of Radicular Dentinal Defects after Using EDTA Gel with Different Rotary Systems: An In-Vitro Study
The purpose of the present study was to study the occurrence of radicular dentinal defects after using EDTA gel during preparation of the root canal with ProTaper Universal (Dentsply Maillefer, Switzerland), HyFlex (ColteneWhaledent, Allstetten, Switzerland), and ProTaper Next (Dentsply Maillefer) rotary instruments. Forty-eight single rooted premolars were selected. Twelve teeth were instrumen...
متن کاملDentinal microcrack formation during root canal preparations by different NiTi rotary instruments and the self-adjusting file.
INTRODUCTION The purpose of this study was to compare dentinal microcrack formation while using hand files (HFs), 4 brands of nickel-titanium (NiTi) rotary files and the self-adjusting file. METHODS One hundred forty mandibular first molars were selected: 20 teeth were left unprepared and served as control, and the remaining 120 teeth were divided into 6 groups. HFs, HERO Shaper (HS; Micro-Me...
متن کاملDentinal crack formation during root canal preparations by the twisted file adaptive, Reciproc and WaveOne instruments
OBJECTIVE This study aimed to compare the frequency of dentinal microcracks after root canal shaping with 2 reciprocating (Reciproc and WaveOne) and 1 combined continuous reciprocating motion twisted files adaptive (TFA) rotary system. MATERIALS AND METHODS Ninety molars were chosen and divided into three groups of 30 each. Root canal preparation was achieved by using Reciproc R25, Primary Wa...
