Effect of Resin Cement System and Root Region on the Push-out Bond Strength of a Translucent Fiber Post
چکیده:   (2993 مشاهده)
Clinical Relevance

 The use of self-adhesive resin cements is an option for bonding fiber-reinforced composite posts to root canal dentin. Traditional resin cements apparently provide higher bond strengths than self-etch resin cements. Because of this, the bond strength of self-adhesive resin cements to root dentin should be evaluated.

SUMMARY

 Objectives:

This study evaluated the bond strength of luting systems for bonding glass fiber posts to root canal dentin. The hypothesis tested was that there are no differences in bond strength of glass fiber posts luted with different cement systems.

 Methods:

 Forty bovine incisors were randomly assigned to five different resin cement groups (n=8). After endodontic treatment and crown removal, translucent glass fiber posts were bonded into the root canal using five different luting protocols (self-cured cement and etch-and-rinse adhesive system dual-cured cement and etch-and-rinse adhesive system self-cured cement and self-etch adhesive system dual-cured cement and self-etch adhesive system and dual-cured self-adhesive cement). Push-out bond strength was evaluated at three different radicular levels: cervical, middle, and apical. The interface between resinous cement and the post was observed using a stereoscopic microscope.

 Results:

 Analysis of variance showed a statistically significant difference among the cements (p<0.05) and the root canal thirds (p<0.05). The self-adhesive resinous cement had lower values of retention.

 Conclusions:

 The resin cements used with etch-and-rinse and self-etch adhesive systems seem to be adequate for glass fiber post cementation.
