Use of nickel-titanium rotary PathFile to create the glide path: comparison with manual preflaring in simulated root canals.
The study compared changes to canal curvature and incidence of canal aberrations after preflaring with hand K-files or with nickel-titanium rotary PathFile in S-shape Endo Training Blocks. The influence of the operator's expertise was also investigated. One hundred training blocks were colored with ink, and preinstrumentation images were acquired digitally. Preflaring was performed by an endodo...
متن کاملMicro-Computed Tomographic Evaluation of 2 Nickel-Titanium Instrument Systems in Shaping Root Canals.
INTRODUCTION Cleaning and shaping without making procedural errors have always been a challenge in endodontics, particularly when the root canals are curved. Several rotary instruments have been developed to minimize such errors. The purpose of this study was to compare the shaping ability of 2 rotary file systems, BioRace (BR; FKG, La Chaux-de-Fonds, Switzerland) and ProTaper Next (PTN; Dentsp...
متن کاملRoot canal preparation of mandibular molars with 3 nickel-titanium rotary instruments: a micro-computed tomographic study.
INTRODUCTION The aim of this study was to describe the canal shaping properties of ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Universal (PTU; Dentsply Tulsa Dental Specialties, Johnson City, TN), and WaveOne (Dentsply Maillefer) nickel-titanium instruments in mandibular first molars by using micro-computed tomographic (micro-CT) scanning. METHODS A total of 36 ...
متن کاملPreparation of oval-shaped root canals in mandibular molars using nickel-titanium rotary instruments: a micro-computed tomography study.
INTRODUCTION This study evaluated the prepared surface areas of oval-shaped canals in distal roots of mandibular molars using four different instrumentation techniques. METHODS Teeth were prescanned and reconstructed using micro-computed tomography (MCT) scans at low resolution (68 microm). Forty-eight molars with ribbon-shaped/oval distal root canals were selected and randomly assigned to fo...
متن کاملLifespan of one nickel-titanium rotary file with reciprocating motion in curved root canals.
INTRODUCTION The purpose of this study was to examine the lifespan of one nickel-titanium (NiTi) rotary file when used in reciprocating motion and to compare the time required for its preparation of a curved root canal using both reciprocating and continuous motion. METHODS One hundred twenty curved canals from 60 extracted maxillary and mandibular molars were selected for measuring the mean ...
