The quality of the enamel plays a critical role in the retention and performance of orthodontic brackets. This systematic review and meta-analysis aimed to evaluate the effect of resin infiltration pretreatment on the shear bond strength (SBS) of orthodontic brackets. An electronic search was conducted in October 2024 using PubMed, Web of Science (WoS), and Scopus databases, employing the keywords (resin infiltration AND bracket); (ICON AND bracket). The review adhered to PRISMA guidelines and utilized the PICO framework. Of the 143 articles initially identified, 63 underwent screening. Strict inclusion criteria were applied of which the most important were resin infiltration pretreatment, studies conducted on natural teeth and SBS evaluation. This left 19 studies for final analysis. The risk of bias was assessed using the checklist for quasi-experimental studies (Non-Randomized Experimental Studies) developed by the Joanna Briggs Institute (JBI). Among these, 13 studies used human teeth and 13 utilized Transbond XT as the adhesive. Metal brackets were predominantly examined ( = 17). The Adhesive Remnant Index (ARI) was assessed in 13 studies. Importantly, 11 studies concluded that resin infiltration significantly enhances SBS, 8 of which were conducted on human teeth. The meta-analysis revealed significantly higher SBS results when resin infiltrate was applied to healthy enamel. This finding underscores the dual benefits of resin infiltration: increased bond strength and the protection of enamel integrity during debonding procedures. The results suggest that resin infiltration not only improves the mechanical retention of orthodontic brackets but also serves as an enamel-preserving approach.
牙釉质的质量在正畸托槽的固位和性能中起着关键作用。本系统评价和荟萃分析旨在评估树脂渗透预处理对正畸托槽剪切粘结强度（SBS）的影响。2024年10月，使用PubMed、科学网（WoS）和Scopus数据库进行了电子检索，使用的关键词为（树脂渗透和托槽）；（ICON和托槽）。该评价遵循PRISMA指南并采用PICO框架。在最初识别的143篇文章中，63篇经过筛选。应用了严格的纳入标准，其中最重要的是树脂渗透预处理、对天然牙进行的研究和SBS评估。最终留下19项研究进行分析。使用乔安娜·布里格斯研究所（JBI）制定的准实验研究（非随机实验研究）清单评估偏倚风险。其中，13项研究使用人牙，13项使用Transbond XT作为粘结剂。主要检查的是金属托槽（ = 17）。13项研究评估了粘结剂残留指数（ARI）。重要的是，11项研究得出结论，树脂渗透显著提高了SBS，其中8项是在人牙上进行的。荟萃分析显示，当将树脂渗透应用于健康牙釉质时，SBS结果显著更高。这一发现强调了树脂渗透的双重益处：提高粘结强度以及在脱粘过程中保护牙釉质完整性。结果表明，树脂渗透不仅改善了正畸托槽的机械固位，还作为一种保护牙釉质的方法。
