Abstract
Aim: To evaluate the cyclic fatigue resistance of Pro Taper NEXT & Reciproc R rotary files in simulated canals with angle of curvaturesat 45o and 60 o.Materials and Methods; This study was conducted at HKE' s S.Nijalingappa institute of dental sciences and reasearch institute,Kalaburagi. After considering the inclusion and exclusion criteria the selected samples were divided into two groups, as G1(ProTaperNEXT) and G2(RECIPROC R), further these two groups are divide into 2 subgroups.Results: The mean cyclic fatigue was significantly high in Reciproc R procedure as compared to ProTaper NEXT. Therefore ReciprocR procedure was better as compared to ProTaper NEXT.Conclusion: Cyclic fatigue resistance of Reciproc R was higher than the ProTaper NEXT.
