摘　　要：修复充填材料与牙体界面间的微渗漏是导致修复体失败的主要原因。大块树脂因增加单次充填厚度、减少聚合收缩、增强牙体抗折裂性,被广泛应用于龋病充填治疗。本文回顾大块树脂微渗漏的相关研究进展,总结大块树脂的分类及性能特点,比较大块树脂与传统树脂在充填不同洞型微渗漏的差异,探讨不同种大块树脂产生微渗漏差异的原因,归纳微渗漏的影响因素,以期为临床治疗提供更好的选择。Microleakage between the filling material and the tooth interface is considered as the most important risk factor responsible for the failure of the restoration. Bulk-fill resin composites(BFRCs)are widely used in the treatment of dental caries because they have the ability to build up increments in single filling,reduce polymerization shrinkage and increase fracture resistance of treated teeth. In this paper,the related research progress on microleakage of BFRCs is reviewed,and the classification and performance characteristics of BFRCs are summarized. The capability of BFRCs and traditional resin against microleakage in filling different types of cavities is compared. The causes of the differences ofmicroleakage in using different kinds of BFRCs are discussed,and the factors causing microleakage are generalized in order to provide better choices for clinical treatment.
