Canal Centring Ability of ProTaper and Mtwo Rotary Systems in Curved Canals
The purpose of this investigation was to compare centring ratio of ProTaper and Mtwo rotary systems. 60 mandibular molar teeth which had 25, 30 and 35 degree curvature in mesio-buccal root canal were used. Group 1 had 25°, Group 2 had 30°, and Group 3 had 35° curvatures. The roots were sectioned horizontally at 2 mm away from the apex. The apical region was then observed under a stereo-microsco...
متن کاملShaping ability of reciprocating single-file and full-sequence rotary instrumentation systems in simulated curved canals
OBJECTIVE The purpose of this study was to evaluate the shaping ability of three nickel-titanium systems in simulated curved canals. MATERIALS AND METHODS Sixty simulated canals were prepared to apical size 25 with Reciproc, S5, and twisted file (TF) instruments. Standardized pre and postoperative images were taken using a digital camera, were superimposed and aberrations were recorded. Mater...
متن کاملShaping ability of Mtwo and Twisted File rotary systems in curved root canals
Objective: To compare the straightening of root canal curvature, the apical transportation, the loss of working length and the working time using two rotary systems. Study design: Sixty buccal root canals with angles of curvature between 30 to 99o were instrumented with Mtwo and Twisted File rotary instruments. A series of preand post-operative radiographs were superimposed to determine the str...
متن کاملA comparative evaluation of the increase in root canal surface area and canal transportation in curved root canals by three rotary systems: A cone-beam computed tomographic study
AIM The aim of this study was to measure the increase in root canal surface area and canal transportation after biomechanical preparation at 1, 3, and 5 mm short of the apex with three different rotary systems in both continuous rotary and reciprocating rotary motions. MATERIALS AND METHODS Sixty freshly extracted human mandibular molars with mesial root canal curvatures between 20° and 30° w...
متن کاملComparison of Shaping Ability of Five Nickel-Titanium Rotary Instruments in Simulated Curved Canals
This study compared the shaping ability of five Ni-Ti rotary files (ProTaper Universal, Reciproc, Hyflex CM, ProTaper Next and TF Adaptive) in simulated root canals. Each group consisted of 10 root canals. Preand post-instrumentation photographs were taken using a precise camera and superimposed with Photoshop. Material removal from the inner and outer canal walls, transportation and centering ...
