摘要: The present study evaluated the influence of 2% chlorhexidine and 2.5% sodium hypochlorite on resin sealer/dentin interface bond strength AH Plus/gutta-percha Epiphany/Resilon. Seventy-two extracted bovine incisors were randomly distributed into 6 groups according to irrigant sealers: G(S+AH)=physiologic saline solution+AH Plus/gutta-percha; G(S+Ep)=physiologic solution+Epiphany/Resilon; G(H+AH)=2.5% (NaOCl)+AH G(H+Ep)=2.5% NaOCl+Epiphany/Resilon; G(C+AH)=2% (CHX)+AH G(C+Ep)=2% CHX+Epiphany/Resilon. After 7 days at 37°C 100% humidity, roots cut transversally long axis tooth in 0.8 mm (±0.09)-thick slices; these slices then subjected push-out test. Data analyzed using a 2-way ANOVA Tukey tests 5% significance. showed significantly higher than Epiphany/Resilon groups, regardless used (p<0.001). Sodium adversely affected Plus group, whereas did not either sealer (p<0.05). Two percent affect sealers, solution damaged strength.
