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.
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.
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).
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.
在文献中尚不清楚根管牙本质中丁香酚的存在是否会削弱用树脂水门汀粘结的纤维桩的固位力。本研究的目的是系统回顾文献并对丁香酚对粘结于根管的桩的粘结强度的影响进行荟萃分析。
在PubMed、Scopus、Lilacs和Web of Science数据库中进行了系统的电子检索。未应用语言或出版日期限制。符合条件的研究是那些评估去除含丁香酚封闭剂后粘结于根管牙本质的桩的即时推出粘结强度，并将其与不含丁香酚的组进行比较的研究。
13项研究符合纳入标准，尽管在全文阅读后排除了2项，通过交叉引用确定了1项研究。9项研究纳入荟萃分析。整体分析显示丁香酚有显著影响，它降低了粘结于根管的纤维桩的粘结强度（P <.001）。与不同类型的杂交过程相关的亚组分析也表明，在所有评估的亚组中丁香酚对粘结强度有负面影响（P <.001）。
含丁香酚的封闭剂会降低用树脂水门汀粘结于根管的纤维桩的即时推出粘结强度，无论使用何种粘结系统或树脂水门汀类型。
