Abstract：
When dental practitioners encounter a defective restoration, they are faced with a crucial decision whether to repair or replace it. This study aims to explore international preferences for repair procedures and the clinical steps taken during the repair process.
An 11-question survey was distributed to dentists across 21 countries via different platforms. The survey comprised two sections: the first included five questions aimed at gathering demographic information, while the second consisted of six questions focusing on participants\' practices related to the repair of composite or amalgam restorations A meta-analysis was employed to ascertain the pooled odds ratio of repairing versus replacement. The statistical analysis was carried out using the RevMan 5.3 program and forest plots were generated using the same program to visualize the results.
The survey was completed by 3680 dental practitioners. The results indicated a strong tendency to repair defective composite restorations (OR: 14.23; 95 % CI: 7.40, 27.35, p < 0.001). In terms of amalgam, there was a significant tendency to replace the restorations (OR: 0.19; 95 % CI: 0.12, 0.30, p < 0.001). When repairing restorations, the most common protocols were etching with orthophosphoric acid and creating an enamel bevel, regardless of the restorative material used.
The findings of this study indicate that there exists a knowledge gap among dental practitioners regarding restoration repair. It is imperative that dental practitioners receive proper education and training on restoration repair, to ensure the usage of adequate protocols and restoration survival.
A significant portion of dental practitioners lack the necessary knowledge and education required for the repair of restorations. Therefore, it is imperative to establish guidelines aimed at enhancing the management of defective restorations, along with protocols for clinical interventions. This includes the incorporation of proper courses in undergraduate, graduate, and continuing education programs.

摘要：
目标：当牙科医生遇到修复缺陷时，他们面临着一个关键的决定是修理还是更换。这项研究旨在探讨国际上对修复程序的偏好以及在修复过程中采取的临床步骤。
方法：一项11个问题的调查通过不同的平台分发给21个国家的牙医。调查包括两个部分：第一部分包括旨在收集人口统计信息的五个问题，第二个问题包括六个问题，重点是与复合材料或汞合金修复修复相关的参与者实践。采用荟萃分析来确定修复与替换的合并比值比。使用RevMan5.3程序进行统计分析，并使用相同程序生成森林地块以可视化结果。
结果：调查由3680名牙科医生完成。结果表明，修复有缺陷的复合修复体的趋势很强（OR：14.23；95％CI：7.40，27.35，p<0.001）。在汞合金方面,存在显著的替换修复体的趋势(OR:0.19;95%CI:0.12,0.30,p<0.001)。修复修复时，最常见的方案是用正磷酸蚀刻并形成牙釉质斜面，无论使用何种修复材料。
结论：这项研究的结果表明，牙科医生在修复修复方面存在知识差距。牙科医生必须接受适当的修复修复教育和培训,以确保使用适当的协议和恢复生存。
