Abstract
Background: Studies on the effect of root canal rinsing protocols on fiber post bonding to dentin are inconclusive. This study reports investigation of this topic. Objectives: to determine effects of irrigation protocol by means of a push-out test on the strength of adhesion between the post and dentin in an in vitro study.
Materials and Method: Thirty human single-rooted teeth were prepared using hand instruments and the step-back technique, filled with gutta-percha, sealed with AH Plus (Dentsply), and divided into three groups: A: rinsed with NaCl; B: rinsed with 2% chlorhexidine (CHX); C: not rinsed before cementa-tion of posts. The fiber posts were set using RelyX and Built-it. The tooth roots were sliced and the push- out test was performed. The area of contact between the post and dentin was calculated and the destroying force was established. The results were statistically analyzed.
Results: The mean adhesive strength was 10.69 MPa in group A, 16.33 MPa in group B, and 16.72 MPa in C. The adhesive strength in group B and C was statistically significantly higher than in group A (p = 0.0016, ANOVA).
Conclusion: Rinsing root canals with CHX seems to be the most effective method prior to setting a fiber post.
