一、龋蚀病因论及遗传龋蚀是多因素性疾患,其中以宿主、微生物、食物摄取三方面为主要因素。而患龋状态因人而异,这就意味着除了这些主要因素之外,还存在着个体差异。个体差异不仅是继承双亲的综合遗传信息,还受环境影响。即个体差异的发生因素可分为遗传因素及环境因素两类。在疾病或个体的特征中,遗传因素有时起决定性作用。而龋蚀的发生必须有龋病病原菌的存在,个体遗传因子的组合本身是不能发生龋蚀的,当然也不能说只有环境因素对龋蚀才有影响。
First, the etiology of cariogenic and genetic caries is a multi-factor disease, including host, microorganisms, food intake in three areas as the main factor. The caries status varies from person to person, which means that in addition to these major factors, there are individual differences. Individual differences not only inherit the parents' comprehensive genetic information, but also affect the environment. The individual differences in the occurrence of factors can be divided into genetic factors and environmental factors in two categories. In the disease or individual characteristics, genetic factors sometimes play a decisive role. The occurrence of caries must exist caries pathogens, the combination of individual genetic factors can not occur caries, of course, can not say that only environmental factors have an impact on caries.
