ABSTRACT
Objective To evaluate the bond strength of GuttaFlow sealers to root canal walls after final rinse with two novel fi nal irrigation regimens, QMiX and 17%EDTA+0.2%Cetrimide (CTR). Methods Thirty single-canal teeth were prepared chemomechanically using 5.25% sodium hypochlorite (NaOCl) as root canal irrigants. The teeth were then randomly distributed into three groups(n=10)according to the final irrigation protocolQMiX group,17% EDTA followed by CTR group and control group(normal saline,NS).After the filling with GuttaFlow using a lentulo spiral,the roots were transversally sectioned to obtain 2 mm thick dentinal slices.Then a push-out bond strength test was carried out,and failure mode was determined at×24 magnification.Results The push-out bond strength was significantly higher in QMiX group than that of EDTA+CTR group and NS group(P<0.05),and no significant difference was observed between EDTA+CTR and NS groups(P>0.05).The failure patterns were mainly mixed.Conclusion The QMiX,as the final irrigant,can improve the bond strength of silicone-based sealer GuttaFlow.
