10.22376/ijpbs.2019.10.1.p1-12 Volume 7 Issue 2 2016 (April - June) The aim of this study was to compare the sealing ability of two different sealers after using chlorhexidine as a final irrigant. Twenty single rooted teeth were randomly divided into two groups according to different obturation materials (the AH Plus, Gutta-percha group and Acroseal, Gutta percha group). The groups were further divided into two subgroups containing five teeth each according to the irrigation regimen, and they were subjected to a universal testing machine for evaluating pushout bond strength. Post hoc pair-wise comparisons were performed using Tukey multiple comparisons for statistical analysis using SPSS 15 Software. The mean value of the AH Plus Gutta-percha group, without precipitate formation revealed the highest mean value for the bond strength, which was statistically higher (P lessThan 0.001) than the remaining groups. Formation of precipitate by combination of sodium hypochlorite and chlorhexidine tends to affect the bond strength of root canal sealers when used for obturation.
