Evaluation of root canal transportation, centering ratio, and remaining dentin thickness associated with ProTaper Next instruments with and without glide path.
INTRODUCTION The purpose of this study was to evaluate and compare the volume of removed dentin, transportation, and centering ability of ProTaper Next (PTN) system with and without glide path preparation by using cone-beam computed tomography (CBCT) imaging. METHODS Sixty mesiobuccal canals of mandibular first molars with curvatures of 25°-35° were divided into 3 experimental groups (n = 20)...
متن کاملRoot canal volume change and transportation by Vortex Blue, ProTaper Next, and ProTaper Universal in curved root canals
Objectives The aim of this study was to compare root canal volume change and canal transportation by Vortex Blue (VB; Dentsply Tulsa Dental Specialties), ProTaper Next (PTN; Dentsply Maillefer), and ProTaper Universal (PTU; Dentsply Maillefer) nickel-titanium rotary files in curved root canals. Materials and Methods Thirty canals with 20°-45° of curvature from extracted human molars were used...
متن کاملApical root canal transportation of different pathfinding systems and their effects on shaping ability of ProTaper Next
BACKGROUND This study aimed to compare glide path preparation of different pathfinding systems and their effects on the apical transportation of ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland) in mesial root canals of extracted human mandibular molars, using digital subtraction radiography. MATERIAL AND METHODS The mesial canals of 40 mandibular first molars (with curvature angles...
متن کاملCentering Ability of ProTaper Next and WaveOne Classic in J-Shape Simulated Root Canals
Introduction. The aim of this study was to evaluate and compare the shaping and centering ability of ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland) and WaveOne Classic systems (Dentsply Maillefer) in simulated root canals. Methods. Forty J-shaped canals in resin blocks were assigned to two groups (n = 20 for each group). Photographic method was used to record pre- and postinst...
متن کاملThe failures of root canal preparation with hand ProTaper
UNLABELLED The failures of root canal preparation are due to some anatomical deviation (canal in "C" or "S") and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. OBJECTIVES Our study was made on technique errors while preparing the canal roots with hand ProTaper. METHODO...
