ABSTRACT
OBJECTIVES:
This study evaluated the effects of intraradicular moisture on the pushout bond strength of a fibre post luted with several self-adhesive resin cements. MATERIALS ANDMETHODS:
Endodontically treated root canals were treated with one of three luting cements (1) RelyX U100, (2) Clearfil SA, and (3) G-Cem. Roots were then divided into four subgroups according to the moisture condition tested (I) dry excess water removed with paper points followed by dehydration with 95% ethanol, (II) normal moisture canals blot-dried with paper points until appearing dry, (III) moist canals dried by low vacuum using a Luer adapter, and (IV) wet canals remained totally flooded. Two 1-mm-thick slices were obtained from each root sample and bond strength was measured using a push-out test setup. The data were analysed using a two-way analysis of variance and the Bonferroni post hoc test with p = 0.05.RESULTS:
Statistical analysis demonstrated that moisture levels had a significant effect on the bond strength of luting cements (p Clearfil SA > G-Cem.CONCLUSIONS:
The degree of residual moisture significantly affected the adhesion of luting cements to radicular dentine.
