ABSTRACT TITLE: Comparative evaluation of pre and post sterilization effect on cyclic fatigue resistance of TruNatomy and One G files in a single curved canal.An in-vitro study AIM : To compare and evaluate the effect of sterilization on cyclic fatigue resistance of TruNatomy and One G glide path files. MATERIALS AND METHODS: A samples of 20 TruNatomy files and 20 One G Ni -Ti glide path files were taken and then 10 from each group were subjected to glass bead sterilization. All the 40 files were fatigue tested by a custom made cyclic fatigue testing device until fracture. Time to fracture and the number of cycles to failure of each instrument was recorded. Data was statistically analyzed by unpaired t test. RESULTS: The cyclic fatigue resistance of sterilized TruNatomy was found statistically high compared to non sterilized TruNatomy, non sterilized One G files and sterilized One G files. CONCLUSION: Within the limitations of the present study ,it was concluded that sterilized TruNatomy files were more cyclic fatigue resistant than non sterilized TruNatomy, non sterilized One G files and sterilized One G files.
