A microbial artificial caries system was used to produce caries-like lesions adjacent to amalgam and composite restorations. Polarised microscopy allowed measurement of outer and wall lesions depths. Comparison was made of the depths found in relation to the restorative materials, margin finishing procedures (composite group), varnish application (amalgam group) and thermal stressing. It was found that differences were detectable between the different restorative materials and the type of margin finishing procedure used in the composite group. Varnish application and thermal stressing had little effect. Some comparison is made between this microbial technique, other artificial caries techniques, and other methods of assessing marginal leakage.
使用微生物人工龋系统在汞合金和复合树脂修复体附近产生类似龋的病变。偏光显微镜可测量外层和壁层病变深度。比较了与修复材料、边缘修整程序（复合树脂组）、涂覆清漆（汞合金组）和热应激相关的病变深度。结果发现，不同修复材料之间以及复合树脂组中使用的边缘修整程序类型之间存在可检测到的差异。涂覆清漆和热应激影响不大。对该微生物技术、其他人工龋技术以及其他评估边缘渗漏的方法进行了一些比较。
