In order to determine the relative influence of genetic and environmental factors in periodontal disease, path analysis has been applied to 241 nuclear families. Common family environment was represented by an index. The data failed to detect significant heritability, and common family environment proved to be a major determinant in the variation of periodontal health.
为了确定遗传因素和环境因素在牙周病中的相对影响,已对241个核心家庭应用了路径分析。共同家庭环境由一个指数表示。数据未能检测到显著的遗传力,并且共同家庭环境被证明是牙周健康变异的主要决定因素。
