The Effect of the Type of Post Space Irrigation on the Push-Out Bond Strength of Glass Fiber Post (An in vitro Study)
Author(s): Raghad Jawad Ali and Alaa Jawad Kadhim*
Aim: The study aims to evaluate the effect of different irrigant and ultrasonic activation on the push-out bond strength of glass fiber post to the root dentine. Materials and Methods: Palatal roots of sixty-four maxillary first molar teeth were sectioned at 14 mm and instrumented with ProTaper Next rotary system up to X4 and obturated with AH Plus sealer and gutta-percha size X4. After post space preparation, the samples were divided into eight groups (n=8) according to the post space irrigation as follow; normal saline (control group), normal saline with ultrasonic activation, 5.25% NaOCl, 5.25% NaOCl with ultrasonic activation, 2% chlorhexidine, 2% chlorhexidine with ultrasonic activation, 17% EDTA and 17% EDTA with ultrasonic activation. RelyX fiber posts were cemented with RelyX U200 cement, the samples were sectioned horizontally, and .. Read More»
