The minimum thickness of a lining material that must be inserted into a cavity in order to afford protection to the dental pulp from thermal trauma has never been determined. By taking the diffusivity ratios of the hard dental tissues, amalgam and lining materials and equating them with the situations incurred in the transmission of thermal energy by the unfilled, as against the restored tooth, it becomes possible to produce a simple table from which measurements serving as guidelines for adequate protection can be taken. An experimental method of confirmation of the hypothesis is described.
为了保护牙髓免受热损伤而必须插入龋洞内的衬里材料的最小厚度从未确定过。通过获取硬牙组织、汞合金和衬里材料的扩散率,并将它们与未填充牙和修复后牙齿在热能传递方面的情况进行等同,可以制作出一个简单的表格,从中可以获取作为充分保护指导的测量值。本文描述了一种验证该假设的实验方法。
