ABSTRACT

Objective: The objective of this study is to evaluate the effect of irrigating agents on push-out bond strength of resin postcemented with various adhesive systems at different radicular dentin sections. Materials and Methods:Sixty single-rooted premolar teeth were root canal treated, subsequently decorated at cementoenamel junction. The endodontic postspace was irrigated with 5.25% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA) for Group A (n = 30) and Group B (n = 30), respectively. The sample from each group was subdivided into three groups (10) according to luting protocol of etch-wash, self-etch, and self-adhesive. Individual teeth with cemented resin postsamples were sectioned into coronal, middle, and apical segments. Subsequently, subjected for pushout bond strength test by applying a load at 0.5 mm/min speed. The data were analyzed by three-way analysis of variance and Tukey comparison test at a significant difference level of 0.05.Results: The coronal section with 5.25% NaOCl irrigation and self-etch luting protocol provided the highest push out strength at 16.282 Mpa. The etch-wash luting protocol in both irrigations showed the lesser bond strength at 8.273 and 8.493 MPa, respectively, in coronal section.Conclusions: The self-etch adhesive system showed better push out bond strength and 17% EDTA had a negative influence on self-etch bond strength. The coronal sections had highest bond strength in comparison with apical radicular dentin sections.

Key words:
