A micro-computed tomographic evaluation of dentinal microcrack alterations during root canal preparation using single-file Ni-Ti systems
The aim of the present study was to evaluate the length of dentinal microcracks observed prior to and following root canal preparation with different single-file nickel-titanium (Ni-Ti) systems using micro-computed tomography (micro-CT) analysis. A total of 80 mesial roots of mandibular first molars presenting with type II Vertucci canal configurations were scanned at an isotropic resolution of...
متن کاملshaping ability of single-file systems with different movements: a micro-computed tomographic study
introduction: this study aimed to perform a rigorous sample standardization and also evaluate the preparation of mesiobuccal (mb) root canals of maxillary molars with severe curvatures using two single-file engine-driven systems (waveone with reciprocating motion and oneshape with rotary movement), using micro-computed tomography (micro-ct). methods and materials: ten mb roots with single canal...
متن کاملA micro-computed tomography evaluation of long-oval canal preparation using reciprocating or rotary systems.
AIM To evaluate, using micro-computed tomography, the preparation of long-oval root canals using a single reciprocating system versus a multiple-file rotary system. METHODOLOGY Distal canals of thirty mandibular molars were selected and randomly assigned to one of two instrument groups (n = 15): Reciproc 40 (VDW, Munich, Germany) or BioRaCe system (FKG Dentaire, La Chaux-de-Fonds, Switzerland...
متن کاملThe Incidence of Dentinal Microcracks Caused by Hand versus Different Rotary Instruments after Biomechanical Preparation: an in Vitro Study
Introduction: The objective of this study was to evaluate the behaviour of different stainless steel and NiTi instruments on root canal dentin. Materials and Methods: Fifty single-rooted premolars were selected. All specimens were decoronated and divided into one control and four experimental groups, each group having 10 samples. Group I is control group, Group II: Hand K-files (Mani), Group II...
متن کاملMicro-computed Tomographic Assessment on the Effect of ProTaper Next and Twisted File Adaptive Systems on Dentinal Cracks.
INTRODUCTION The aim of the present study was to evaluate the frequency of dentinal microcracks observed after root canal preparation with ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland) and Twisted File Adaptive (TFA; SybronEndo, Orange, CA) systems through micro-computed tomographic analysis. METHODS Twenty moderately curved mesial roots of mandibular molars presenting a ty...
