A COMPARATIVE EVALUATION OF FLEXURAL FATIGUE RESISTANCE OF PROTAPER NEXT AND PROFILE VORTEX: AN IN-VITRO STUDY.

Journal Title: Journal of Biomedical and Pharmaceutical Research - Year 2017, Vol 6, Issue 1

Abstract

Background: Introduction of nickel titanium file system for root canal therapy has changed the conventional approach but instrument fracture in curved and narrow root canal still remains a challenge for operator. Aim & objective: This study aimed to compare the cyclic fatigue fracture resistance of two recent rotary Ni Ti file systems: Protaper Next and Profile Vortex file system. Methodology:The cyclic fatigue testing was conducted with the files rotating freely at an angle of curvature 60⁰ with maximum radius of curvature at 5mm from the tip. Ten endodontic rotary files were selected in each of the two groups to be tested. The files were rotated at 400 rpm using the Tri auto mini endomotor with handpiece set at 2.5 Torque, until the fracture occurred. The time until fracture was recorded in seconds by using a stopwatch, and the number of rotations till fracture was then calculated and results were then statistically analyzed. Result:The results showed Protaper Next performed significantly (P < 0.001)better and had good survival time than Profile Vortex rotary file system during cyclic fatigue testing.Conclusion:It was concluded that Protaper Next files had greater resistance to cyclic fatigue than Profile Vortex file system. Keywords:CyclicFatigue, Flexural fracture, Flexural resistance.
