目的：对不同国家的置换原因进行了调查。本文的目的是汇集和审查的数据10个这样的调查与类似的methods.METHOD：研究审查都是基于Mjor在1981年描述的协议。结果：调查审查提供的数据的原因，安置和更换共32,777个牙。尽管各国之间存在差异，不同的从业者群体和方法略有不同，但选定调查中的数据表明，在20世纪80年代和90年代，斯堪的纳维亚、英国和美国的日常临床实践中，更换比初始置换更多，初始置换与更换置换的比例范围为1：1.1至1：2.4（汞合金）和1：1.1至1：3.8（复合材料）。原发性龋齿一直被认为是提供汞合金和复合材料的初始替代品的主要原因。临床上诊断的继发龋仍然是替换银汞合金和复合材料的主要原因。材料失效（边缘降解、变色、大块断裂和解剖形状丧失）导致复合材料比汞合金置换更多。最近的调查报告继发性龋失败的discriminations的玻璃离子水门汀和相关material.CONCLUSIONS：龋齿的临床诊断可能会继续被发现占大多数intracoronal discriminations的安置和更换的主要原因。审查的类型的调查提供了宝贵的洞察模式提供牙科保健和突出的研究优先事项，直接牙科治疗。
AIM: Surveys on reasons for the placement and replacement of restorations have been conducted in various countries. The purpose of this paper is to bring together and review the data of 10 such surveys with similar methodology.METHOD: The studies reviewed are all based on the protocol described by Mjor in 1981.RESULTS: The surveys reviewed provide data on the reasons for the placement and replacement of a total of 32,777 restorations. Notwithstanding differences between countries, different groups of practitioners and minor variations in methodology, the data included in the selected surveys indicate that everyday clinical practice in Scandinavia, UK and USA during the 1980s and 1990s has involved more replacement than initial restorations, with the ratio of initial to replacement restorations ranging from 1:1.1 to 1:2.4 for amalgam and 1:1.1 to 1:3.8 for composite materials. Primary caries has been consistently found to be the principal reason for the provision of initial restorations of amalgam and composite. The principal reason for the replacement of restorations of amalgam and composite has remained secondary caries as diagnosed clinically. Material failures (marginal degradation, discoloration, bulk fracture and loss of anatomic form) accounted for the replacement of more restorations of composite than amalgam. Recent surveys have reported secondary caries as the principal cause of failure of restorations of glass-ionomer cements and related materials.CONCLUSIONS: The clinical diagnoses of caries may continue to be found to account for the placement and replacement of most intracoronal restorations. Surveys of the type reviewed provide valuable insight into patterns of provision of dental care and highlight research priorities in relation to direct restorations.
