The effect of different solutions on bond strength of two root canal sealers

摘要

Objective: The aim of this study was to evaluate the effect of different solutions on bond strength?of two root canal sealers. Methods: Sixty bovine incisor roots were randomly divided into five groups: group 1, physiologic solution (control); group 2, 2% chlorhexidine digluconate (CHX) followed by EDTA; group 3, CHX followed by EDTA and ethanol (EtOH); group 4, 5.25% sodium hypochlorite (NaOCl) followed by EDTA; and group 5, NaOCl followed by EDTA and EtOH. Each group was subdivided into two subgroups: AH Plus and MTA Fillapex sealers. Bond strength was measured by push-out test and were analyzed statistically by two-way ANOVA and Tukey’s (a=0.05). Results: The different irrigating protocols did not influence the bond strength of either sealer?(p&0.05). AH Plus sealer showed higher values of bond strength to root dentin than MTA Fillapex?(p&0.05). Conclusion: The bond strength of AH Plus and MTA Fillapex were not influenced by different?solutions.
