Abstract
An vitro method of toxicity testing of dental restorative materials is described in which their clinical usage is closely simulated. The test material was separated from the cells by either a synthetic filter or dentine slice. Toxic effects were quantiated by determining changes in enzyme activity by scanning and integrating microdensitometry.
摘要
本文描述了一种牙科修复材料毒性测试的体外方法，该方法紧密模拟了它们的临床使用情况。测试材料通过合成滤膜或牙本质切片与细胞分离。通过扫描和积分显微密度测定法测定酶活性的变化来量化毒性作用。
