Title

ROLE OF MANUAL GLIDE PATH ON BETTER USE OF ROTARY MTWO INSTRUMENTS

Pages

  184-190

Abstract

 Background & Aim: Increased FRACTURE rate of different rotary NiTi files has influenced the prognosis of root canal therapies. Torsion fatigue is one of the most important factors influencing the FRACTURE rate of these rotary instruments; due to increased contact area between file and canal walls. The MANUAL GLIDE PATH is one of the recommended methods to decrease this problem. The purpose of this study was to investigate the influence of MANUAL GLIDE PATH on FRACTURE or separation rate of NiTi rotary instruments.Materials & Methods: This experimental study was conducted using 160 root canals of human molar teeth with mild curvature of 15 to 35 degrees. Samples were divided into two groups. In group one MANUAL GLIDE PATH was carried out with k-type SS#10-20. The final preparation was performed with Mtwo files using crown down technique. The root canals in group two were instrumented with Mtwo files without prior application of MANUAL GLIDE PATH procedure. Data were collected and analyzed using ANOVA, Mann-Whitney and Mantel-Cox tests.Results: Based on the results of this study, the three variables under investigation in both groups showed significant differences with each other when the DEFECT (P=0.039); FRACTURE or DEFECT (P=0.005), and number of prepared canals (P=0.042) were compared. Survival analysis of Kaplan-Meier demonstrated that, the safety probability after preparation of 10 canals were 81.5% and 53.7% in group one and two respectively. The Mantel–Cox test showed significant difference between the two groups in terms of file working time (P=0.002).Conclusion: Based on these results, the FRACTURE and DEFECT can considerably be decreased when using SS hand files for preparation of apical third, before using NiTi rotary instruments.
