Evaluation of The Cleaning Protocol of Post Space on Bond Strength of Glass Fiber Posts

This study aimed to compare the effect of four irrigation solutions for post space cleaning on bond strength between glass fiber and root dentine. Forty bovine roots were root-filled randomly divided into groups (n=10), according solution: CG (Control Group): saline solution; SH (Sodium Hypochlorite Group); CLX (Chlorhexidine group) EDTA (ethylenediaminetetraacetic acid group). Specimens submitted mechanical aging push-out test. Statistical analysis (ANOVA two-way Tukey test; p<0.05) was performed. A stereomicroscope used failure mode classification. showed higher values, differing statistically from (p<0.05). Adhesive dentin resinous cement predominant, followed by mixed failures. SEM images pronounced smear layer removal in group. 17 % better than other when using posts.
