Abstract
INTRODUCTION: It is unclear in the literature if the presence of eugenol in root dentin impairs the retention of a fiber post luted with resin cements. The aim of this study was to systematically review the literature and perform meta-analysis on the influence of eugenol on the bond strength of posts luted to root canals. METHODS: A systematic electronic search was performed in PubMed, Scopus, Lilacs, and Web of Science databases. No language or publication date restrictions were applied. Eligible studies were those that assessed the immediate push-out bond strength of posts cemented to root dentin after the removal of eugenol-based sealer and compared it with a eugenol-free group. RESULTS: Thirteen studies met the inclusion criteria although 2 were excluded after full-text reading and 1 study was identified by cross-reference. Nine studies were included in the meta-analysis. Global analysis showed a significant influence of eugenol, which lowered the bond strength of fiber posts cemented to root canals (P < .001). The subgroup analysis carried out related to the different types of hybridization processes also indicated a negative effect of eugenol on bond strength in all subgroups assessed (P < .001). CONCLUSIONS: Eugenol-based sealer reduces the immediate push-out bond strength of fiber posts luted to root canal with resin cement, regardless of the type of adhesive system or resin cement used.
