This study aimed to identify factors that can affect the retention of glass fiber posts to intra-radicular dentin based on in vitro studies that compared the bond strength (BS) of GFPs cemented with resin cements. Searches were carried out in PubMed and Scopus until December 2013. Bond strength values and variables as type of tooth, presence of endodontic treatment, pretreatment of the post, type of bonding agent (if present), type of cement and mode of cement application were extracted from the 34 included studies. A linear regression model was used to evaluate the influence of these parameters on BS. The presence of endodontic treatment decreased the BS values in 22.7% considering the pooled data (p = 0.013). For regular cement, cleaning the post increased BS when compared to silane application without cleaning (p = 0.032), considering cleaning as ethanol, air abrasion, or phosphoric acid application. Applying the cement around the post and into root canal decreased the resistance compared to only around the post (p = 0.02) or only into root canal (p = 0.041), on the other hand, no difference was found for self-adhesive resin cement for the same comparisons (p = 0.858 and p = 0.067). Endodontic treatment, method of cement application, and post pretreatment are factors that might significantly affect the retention of glass-fiber posts into root canals mainly when cemented with regular resin cement. Self-adhesive resin cements were found to be less technique-sensitive to luting procedures as compared with regular resin cements.
本研究旨在基于体外研究确定可能影响玻璃纤维桩与根管内牙本质固位的因素，这些研究比较了用树脂水门汀粘结的玻璃纤维桩的粘结强度（BS）。截至2013年12月，在PubMed和Scopus中进行了检索。从纳入的34项研究中提取了粘结强度值以及牙齿类型、牙髓治疗情况、桩的预处理、粘结剂类型（如有）、水门汀类型和水门汀应用方式等变量。使用线性回归模型评估这些参数对粘结强度的影响。考虑汇总数据时，牙髓治疗的存在使粘结强度值降低了22.7%（p = 0.013）。对于常规水门汀，与未清洁的硅烷应用相比，清洁桩可提高粘结强度（p = 0.032），清洁方式为乙醇、空气喷砂或磷酸应用。与仅在桩周围或仅在根管内应用水门汀相比，在桩周围和根管内应用水门汀会降低抗力（p = 0.02或p = 0.041），另一方面，对于自粘结树脂水门汀，相同比较未发现差异（p = 0.858和p = 0.067）。牙髓治疗、水门汀应用方法和桩的预处理是可能显著影响玻璃纤维桩在根管内固位的因素，主要是在用常规树脂水门汀粘结时。与常规树脂水门汀相比，发现自粘结树脂水门汀对粘结程序的技术敏感性较低。
