Abstract:
The aim of this study was to perform a morphometric evaluation of the resin-root canal dentine interface of four "etch and rinse" adhesive systems. Forty human teeth were restored through a fiber post insertion using: Group 1: XP Bond adhesive; Group 2: Prime & Bond NT; Group 3: Surgi Prime Bond adhesive; Group 4: Scotchbond Multi-Purpose Plus. Two cross-sections (apical and coronal) were obtained and analyzed in morphological confocal laser scanning microscope. The numbers of resin tags (RT) and the thickness of the hybrid layer (HL) were evaluated. Quantitative variables were tested by a Shapiro-Wilk test. Parametric variables by an Anova test. Group 4 produced the thickest HL and Group 1 showed the thinnest. Considering RT, Group 1 produced the highest density, while Group 3 the lowest density. All the adhesives produced good results in terms of HL thickness and RT density.
