The Effect of Different Irrigation Regiments on the Push out Bond Strength of MTA Fillapex Sealer to Dentin
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2015, Vol 9, Issue 1
Abstract
Aims: The purpose of this study was to compare the effect of various irrigation regiments on the push out bond strength of MTA Fillapex sealer to dentin. Study Design: Cross-sectional study. Place and Duration of Study: Department of Conservative dentistry and Endodontics, Hitkarni Dental College and Hospital (HDCH), between November 2014 and December 2014. Methodology: Thirty single-rooted premolar teeth were taken. Roots were divided into 3 groups according to the irrigation regiment used and instrumented using 5% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) irrigants as chemical auxiliary substances and 17% Ethylenediaminetetraacetic acid (EDTA) or 50% citric acid for smear layer removal. Finally, CHX solution was used as the final irrigant in one group. Root canals were filled with gutta-percha and MTA fillapex (Angelus, Londrina, PR, Brazil),a resin-based sealer. Bond strength was measured by the push-out test. Data were statistically analyzed by Kruskal-Wallis and Mann-Whitney U tests. Results: In the present study, specimens in G1 (NaOCl + EDTA + Distilled Water) & G2 (CHX + EDTA+ Distilled Water) group show lower push out bond strength values than G3 (NaOCl+ EDTA + Citric Acid +CHX) group. Conclusion: Thus, within the limitations of this study, we conclude that the different irrigation regiments did affect the push out bond strength of MTA Fillapex sealer to dentin. However the significant changes were not found between the various groups.
