Shaping 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...

Shaping 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...

Comparison of the shaping ability of RaCe, FlexMaster, and ProFile nickel-titanium instruments in severely curved root canals

BACKGROUND This in vitro study compared the shaping ability of RaCe, FlexMaster, and ProFile rotary nickel-titanium instruments in severely curved root canals of extracted teeth. MATERIAL AND METHODS Sixty maxillary molars with curvatures ranging from 25° to 65° were embedded in a muffle system and portioned into five horizontal sections (thickness 1.2 mm), starting from the apex. Canals were...
