Comparison of canal transportation in simulated curved canals prepared with ProTaper Universal and ProTaper Gold systems.
OBJECTIVES The purpose of this study was to assess the ability of ProTaper Gold (PTG, Dentsply Maillefer) in maintaining the original profile of root canal anatomy. For that, ProTaper Universal (PTU, Dentsply Maillefer) was used as reference techniques for comparison. MATERIALS AND METHODS Twenty simulated curved canals manufactured in clear resin blocks were randomly assigned to 2 groups (n ...
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 کاملGeometric and dimensional characteristics of simulated curved canals prepared with proTaper instruments
OBJECTIVE This study identified which regions of ProTaper instruments work during curved root canal instrumentation. MATERIAL AND METHODS Twelve ProTaper instruments of each type, S1, S2, F1, and F2, were assessed morphometrically by measuring tip angle, tip length, tip diameter, length of each pitch along the cutting blades, and instrument diameter at each millimeter from the tip. Curved can...
متن کاملApical transportation associated with ProTaper® Universal F1, F2 and F3 instruments in curved canals prepared by undergraduate students
OBJECTIVE This study evaluated apical transportation associated with ProTaper Universal Fl, F2 and F3 rotary files in curved canais prepared by undergraduate students. MATERIAL AND METHODS Twenty mesial roots of mandibular molars with curvatures ranging between 25° and 35° were selected. Mesiobuccal canals were instrumented by twenty students with the ProTaper system (Dentsply-Maillefer, Ball...
متن کاملComparison of the shaping characteristics of Neolix and Protaper Universal systems in preparation of severely-curved simulated canals
BACKGROUND The aim of this in vitro study was to compare the shaping characteristics of two types of nickel-titanium endodontic file systems with regard to the following parameters: Canal straightening, Canal deviation and Instrumentation time. MATERIAL AND METHODS Fifty severely curved canals simulated in resin blocks were prepared to an apical size 25 using Protaper Universal orNeolix syste...
