Replica techniques have been widely used in dental research, but not previously applied to the in vivo study of carious cavities on free smooth surfaces. A replica method was developed using an epimine resin as the impression material, and a silicone elastomer as the casting material. Cavity areas were measured on the replicas using the Reflex microscope. The sources of method error were identified and quantified. The method was successfully incorporated into a conventional clinical trial and changes in cavity size with time were investigated.
复制技术已在牙科研究中广泛应用，但此前未应用于自由光滑表面龋洞的体内研究。本研究开发了一种复制方法，使用表亚胺树脂作为印模材料，硅橡胶作为浇铸材料。使用反射显微镜在复制件上测量龋洞面积。识别并量化了方法误差来源。该方法成功应用于一项传统临床试验，并研究了龋洞大小随时间的变化。
