根据牙龈颜色和轮廓、牙周袋深度、探诊时出血和放射学测量的永久性骨丢失对牙龈部位进行临床评估。使用厌氧技术，龈下菌斑收集这些网站进行检查的存在下，黑色色素拟杆菌（BPB）。通过生化试验和革兰氏染色形态学鉴定BPB。除了一个例外，只有糖解菌株（B.产黑色素菌）在正常和牙龈炎部位发现，而这些和溶砷菌株（B.溶砷菌）在表现出骨丢失的部位被发现。
Gingival sites were clinically evaluated on the basis of gingival color and contour, pocket depth, bleeding upon probing and peercent bone loss as measured radiographically. Using anaerobic techniques, subgingival plaque collected from these sites was examined for the presence of the black-pigmented Bacteroides (BPB). The BPB were identified by biochemical testing and Gram stain morphology. With one exception, only saccharolytic strains (B. melaninogenicus) were found at normal and gingivitis sites, while these and asaccharolytic strains (B. asaccharolyticus) were found at sites exhibiting bone loss.
