On the basis of a survey of the literature, the author emphasizes the considerable clinical importance of secondary caries and the dependence of its incidence upon the filling material used. Further predisposing factors (such as marginal leakage, cavity preparation, age and size of the filling, and the kind of cavity wall working) are discussed, and relevant measures for the prevention of secondary caries are presented.
基于对文献的调研，作者强调了继发龋的重要临床意义及其发病率与所用充填材料的相关性。文中还讨论了其他易感因素（如边缘渗漏、窝洞预备、充填体的年龄和大小以及洞壁处理方式），并提出了预防继发龋的相关措施。
