牙体修复后充填材料的微渗漏可导致充填体边缘着色、继发龋、牙髓病变以及根管治疗最终失败等不良后果。影响充填体微渗漏的因素有充填材料的类型、洞型的制备、牙体组织自身结构和牙髓组织的活力等,本文就有关微渗漏的研究进展加以综述。 Microleakage of the filler material after tooth restoration can result in coloration of the filler body, secondary caries, endodontic lesions, and ultimately failure of root canal treatment. Factors that affect the microleakage of the filling body are the type of filling material, the preparation of the hole type, the structure of tooth tissue itself and the activity of dental pulp tissue. In this paper, the research progress on microleakage is reviewed.
