摘　　要：作者对13例根面龋患者病灶微生态系中的变形链球菌、乳酸杆菌、粘性放线菌进行定量研究。结果显示,变形链球菌在数量上占绝对优势,乳酸杆菌也较多,而粘性放线菌仅在1例中检出。故支持变形链球菌是根面龋和冠龋共同病原菌的观点。Thirteen primary root surface carious lesions in 13 patients were included in this study. The sample of plaque from sound root surfaces and sample of carious material from root lesions were taken using a standardised sampling procedure. The numbers of mutatis streptococci lactobacilli and actinomyces viscosus were determined. These data indicate that the number of mutans streptococci is significantly greater, and lactobacilli is also a lot, but the actinomyces viscosus is detected one case only. Our findings support the opinion that mutans streptococci is cooperative germ of root surface carious lesion and coronal caries.
