摘要
目的 :分析变形链球菌和放线菌与根面龋的关系。方法 :用选择性培养基MS和BYS对 30例根面龋中的变形链球菌、放线菌定量研究。结果 :放线菌的检出率 10 0 % ,变形链球菌的检出率 93.33% ,放线菌在数量上 (CFU)占绝对优势 ,与变形链球菌数量相比有高度显著性差异 ,P <0 .0 1。结论
Objective: To analyze the relation ship between Streptococcus mutans, Actinomyces and dental root surface caries. Methods: Streptococcus mutans and Actinomyces in 30 cases of dental root surface caries are studied quantitatively by selective media. Results: The postive detection rate of Actinomyces is 100% while that of Sreptococcus mutans is 93.33%. And Actinomyces has absotrtely dominance in CFU compared with Streptococcus mutans. The result has significant difference in statistics. (P<0.01). Conclustion: Actinomyces is the mainly dominant bacterium in root surface caries. [
