Effects of Reciproc, Mtwo and ProTaper Instruments on Formation of Root Fracture
INTRODUCTION The aim of this study was to compare the formation of dentinal crack and craze lines in the root dentin during root canal preparation with three different NiTi endodontic systems, naming Reciproc (RCP), ProTaper Universal (PTU) and Mtwo. METHODS AND MATERIALS One hundred extracted mandibular premolars with single canals were selected and decoronated. The teeth were randomly divid...
متن کاملComparison of root microcrack formation after root canal preparation using two continuous rotational file systems and two reciprocating systems –An Invitro study
Aim:To compare the incidence of dentinal defects after preparation with reciprocating (Reciproc and WaveOne) and fullsequence rotary ProTaper Universal and Protaper Next instruments. Materials and methods:One hundred human mandibular premolars were randomly assigned to 5 groups (n = 20 teeth per group). The root canals were instrumented by using the reciprocating single-file systems Reciproc an...
متن کاملShaping ability of ProTaper NEXT and BT-RaCe nickel-titanium instruments in severely curved root canals.
AIM To compare the shaping ability of four different nickel-titanium rotary instruments during the preparation of curved root canals in extracted teeth. METHODOLOGY A total of 80 root canals with curvatures ranging between 25° and 39° were divided into four groups of 20 canals. Based on radiographs taken prior to instrumentation, the groups were balanced with respect to the angle and the radi...
متن کاملThe effects of autoclave sterilization on the cyclic fatigue resistance of ProTaper Universal, ProTaper Next, and ProTaper Gold nickel-titanium instruments
Objectives It was aimed to compare the cyclic fatigue resistances of ProTaper Universal (PTU), ProTaper Next (PTN), and ProTaper Gold (PTG) and the effects of sterilization by autoclave on the cyclic fatigue life of nickel-titanium (NiTi) instruments. Materials and Methods Eighty PTU, 80 PTN, and 80 PTG were included to the present study. Files were tested in a simulated canal. Each brand of ...
متن کاملcomparison of dentinal crack formation with reciproc, mtwo and protaper root canal preparation systems
conclusions regarding the study limitations, dentinal cracks were observed in all files and distances from the apex. although there was more crack incidence in protaper files, no significant differences were noted regarding the studied systems and sections from the apex. materials and methods in an experimental in vitro trial, 80 maxillary and mandibular first molars were selected and their cro...
