Comparative Study of Bond Strength of Four Resin Cements Used for Endodontic Glass-fibre Posts
Deng, Xin / Tan, Jian Guo / Zhou, Jian Feng / Chen, Li
Objective: To assess the interfacial bond strength of total-etch, two self-etch and self-adhesive resin cement luted endodontic glass-fibre posts.
Methods: Sixteen recently extracted human teeth were collected for this study. The teeth were randomly and equally allocated to four groups: group 1, Single Bond 2 (3M ESPE, Seefeld, Germany) in combination with RelyX ARC (3M ESPE, Seefeld, Germany); group 2, ED Primer with Panavia F (Kuraray Co., Okayama, Japan); group 3, ParaBond with ParaCem (Coltène/Whaledent, Altstatten, Switzerland); and group 4, RelyX Unicem (3M ESPE, Seefeld, Germany). Fibre posts were cemented in endodontically treated teeth within the groups. One week later, the cemented posts in each group were processed for thin-slice pushout tests after thermal cycling (1000 cycles, 5/55 °C).
Results: The interfacial bond strength was not different among the four groups. The bond strength was significantly higher at the coronal third of the root canal than at the middle- apical third for group 4. The rest of the groups did not show regional differences in bond strength.
Conclusion: Single Bond/RelyX ARC, Panavia F, ParaCem, and RelyX Unicem demonstrated an equal potential for adhesion of fibre posts to intraradicular dentine.
