This systematic review aimed to determine the presence of any proof to validate the utilization of surface treatments to advance the bond strength of fiber posts to intraradicular dentin with self-adhesive resin cements.
Laboratory studies that assessed the push-out or pull-out bond strength of the prefabricated esthetic posts whose surface was treated with either chemical or physical treatment or a combination and bonded using self-adhesive resin cement within root canal model were included for this systematic review. The review began after obtaining the registration number from the International Prospective Register of Systematic Reviews (PROSPERO ID-CRD42020165009). Study reporting was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant articles were identified using a literature database search in Web of Science, Scopus, PubMed, and EBSCO. Besides this, handsearch was also done to ensure complete capture of the articles.
Fifteen articles were then selected and included in this study, out of which four were excluded for meta-analysis due to usage of the artificial substrate. It was shown that an additional step of surface treatment of esthetic fiber post did not result in significant improvement in dislocation resistance. Assessment of risk of bias categorized the available research into high risk and medium risk. The results showed heterogeneity.
The use of additional steps such as chemical, mechanical, or a combination of post surface treatment does not have any added benefit. However, the results must be interpreted with caution due to methodological shortcomings.
本系统评价旨在确定是否存在证据来验证使用表面处理方法以提高纤维桩与根管内牙本质之间的粘结强度，并使用自粘结树脂水门汀。
本系统评价纳入了实验室研究，这些研究评估了预制美学桩的推出或拔出粘结强度，这些桩的表面经过化学或物理处理或两者结合处理，并在根管模型中使用自粘结树脂水门汀进行粘结。在从国际系统评价前瞻性注册库（PROSPERO ID-CRD42020165009）获得注册号后开始进行该评价。研究报告遵循PRISMA（系统评价和Meta分析的首选报告项目）指南进行。通过在Web of Science、Scopus、PubMed和EBSCO中进行文献数据库搜索来识别相关文章。除此之外，还进行了手工检索以确保完整收录文章。
然后选择了15篇文章纳入本研究，其中4篇由于使用人工基质而被排除在Meta分析之外。结果表明，美学纤维桩表面处理的额外步骤并未导致抗脱位能力的显著提高。偏倚风险评估将现有研究分为高风险和中风险。结果显示存在异质性。
使用化学、机械或桩表面处理组合等额外步骤没有任何额外益处。然而，由于方法学上的缺陷，对结果的解释必须谨慎。
