【摘要】：正根面龋是导致失牙的主要病因之一。第三次全国口腔健康流行病学调查报告〔1〕显示,全国65~74岁老年人患龋率为98.4%,根龋患病率为63.6%。本文探讨根面龋的病因及预防方法。1病因1.1主要因素细菌分解有机底物产酸、促使牙齿脱矿是龋形成过程中一个重要因素。有机物的分解作用在根面龋形成过程中尤其明显。据有关报道根面龋的优势菌是变形链球菌,其次是放线菌〔2〕。在根面龋形成过程中,细菌胶原酶对于牙的
[Abstract]:Orthodontic caries are one of the main causes of tooth loss. The results of the third National Oral Health Epidemiology Survey showed that the prevalence rate of caries and root caries was 98.4 and 63.6respectively. This paper discusses the etiology and prevention of root caries. 1 the main factor of etiology 1.1 is that bacteria decompose organic bottom products to produce acid and promote tooth demineralization is an important factor in the process of caries formation. The decomposition of organic matter is especially obvious in the process of root caries formation. Streptococcus mutans was the dominant bacteria in root caries, followed by actinomycetes. In the process of root caries formation, the effect of bacterial collagenase on teeth
