Effect of Resin Cement System and Root Region on the Push-out Bond Strength of a Translucent Fiber Post

Abstract: 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. SUMMARYObjectives: 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 stren… Show more

“…When considering the polymerization reaction, the cementation of an intraradicular post can be performed using a chemically cured resin cement (self-curing), which polymerizes by mixing a base paste and a catalyst, or by using a dual cured resin cement (photoactivated and chemically cured) [7][8][9] . However, the irradiation of light necessary to initiate the conversion of monomers into polymers is hindered by factors, such as root anatomic characteristics, power of the light emitted, distance from the curing light in relation to the cement, translucency of the post, amount and position of fiber in the post, amount of filler in the post and cement, monomer type and cement opacity degree 1,3,10 . When the polymerization degree of the resin cement does not reach satisfactory levels, its mechanical properties are compromised 6,11,12 .…”

“…Thus, laboratory studies evaluated different parameters in order to obtain a reliable adhesion between resin cement and dentin through which the lifespan of reconstructions on endodontically treated teeth restored FRC and core could be prolonged [1]. The effect of canal preparation [4], hybridization methods of root canal dentin [5], resin cement [5][6][7][8][9][10][11][12][13][14][15][16][17], polymerization methods for the resin cement [18], and post configuration [6,19] have been studied and deemed to show effect on the bond strength of FRC posts. In fact, according to the clinical workflow, immediately after post cementation, the core is built up and it is prepared with rotating hand-pieces, which may cause torque forces to the newly cemented post until final polymerization reached.…”

“…This is explained by the deficient dentin hybridization 18,23,24 and incomplete smear layer removal promoted by its weak-acid monomers and hydrolysis of adhesive components 7 . Given these discrepancies, the bonding behavior of cements deserves further studies, especially since the high variability of the root canal environment hinders the application of cementation techniques.…”
