Title

A COMPARISON OF MTWO ROTARY FILE WITH K-FILE ON NEGOTIATION OF SECOND MESIOBUCCAL CANAL IN MAXILLARY FIRST MOLAR: A CLINICAL STUDY

Pages

  29-32

Abstract

 Introduction: This study was carried out to compare the capability of K-files with Mtwo rotary file in tenns of NEGOTIATION as well as depth of penetration in second mesiobuccal (MB2) canal of MAXILLARY FIRST MOLAR. Materials and Methods: Atotal of 32 MB2 canal of MAXILLARY FIRST MOLARs having different root curvatures (not more than 30 degree) and root lengths were selected and then detected by K-file #10, #8 and #6. Based upon file penetration the samples were assigned into four groups. Group A:K-file#10 penetrate>2 mm into coronal third, group B:K-file#10 could penetrate<2mm into coronal third, continue proceeding with #8 which had>2mm penetration, group C: K-files #10 and 8 could penetrate<2mm, continue proceeding with #6 for deeper penetration, and group D: MTWO FILE #10/.04 was applied into all three above groups until resistance was felt. Finally, accurate working lengths at each group after K-file #10 insertions into the canal were determined radiographically. The mean depths of ROOT CANAL penetration were analyzed statistically using Duncan test by SAS software (version 9.1) in GLM procedure.Results: The mean of initial penetration for #10 MTWO FILEs was 19.16mm, whilst it was 7.72 mm for K-File #6, 10.72 mm for K-File #8, and 12mm for K-File#10. The difference between Mtwo rotary files and hand K-Files was statistically significant (P<0.01).Conclusion: Mtwo rotary files could be an efficient substitute for hand files to negotiate MB2 canal both more easily and rapidly. Toour knowledge, it is the first time that a NiTi rotary file showed success in NEGOTIATION of any canal.
