Abstract

Aim:

The aim of the study was to evaluate the effect of different final irrigation protocols on the push-out bond strength of an epoxy resin sealer to the tooth dentin.

Materials And Method:

Thirty single-rooted teeth were collected. The canals were shaped using a rotary system. The final diameter was established using a #5 Gates-Glidden drill. For final irrigation 5.25% NaOCl solution was used followed by 17% EDTA. The sample was divided into three groups according to final irrigant using NaOCl, curcumin or grape seed extract. The canals were finally obturated with AH Plus sealer. Push out bond strength was measured under UTM. Data was statistically analysed by ANOVA and Post-hoc Tukey HSD method.

Results:

NaOCl/EDTA/NaOCl group showed significantly superior bond strength values in comparison to other groups as final irrigating regimen.

Conclusion: 

The group with 5.25% NaOCl combined with EDTA showed the most efficient solution.
