This investigation was designed to compare the predominant plaque micro-organisms from a Chinese group of patients exhibiting periodontitis with an age-, sex- and periodontal disease-matched Caucasian group of patients. In addition to race, the 2 population groups differed with respect to diet and oral hygiene habits, or effectiveness at removing plaque. Clinical measurements were determined along with an evaluation for micro-organisms in supragingival and subgingival plaque. Although the Chinese and Caucasian population groups were similar with respect to composition of micro-organisms in subgingival plaque, notable differences were observed in supragingival plaque. The Chinese group had higher mean proportions of spirochetes, motile rods. Fusobacterium spp. and dark-pigmented Bacteroides species, while the Caucasian group had higher mean proportions of cocci, total Actinomyces spp., A. viscosus and total Streptococcus spp. in supragingival plaque. The microbial differences observed in supragingival plaque may be explained at least in part, if not totally, by the higher plaque index scores of the Chinese versus Caucasian population groups.
本研究旨在比较一组患有牙周炎的中国患者与一组年龄、性别和牙周疾病相匹配的白种人患者的主要菌斑微生物。除种族外，这两组人群在饮食、口腔卫生习惯或清除菌斑的效果方面也存在差异。同时进行了临床测量，并对龈上和龈下菌斑中的微生物进行了评估。尽管中国人群和白种人群在龈下菌斑微生物组成方面相似，但在龈上菌斑中观察到了显著差异。中国人群龈上菌斑中螺旋体、活动杆菌、梭杆菌属和产黑色素拟杆菌属的平均比例较高，而白种人群龈上菌斑中球菌、总放线菌属、粘性放线菌和总链球菌属的平均比例较高。龈上菌斑中观察到的微生物差异至少部分（如果不是全部）可以用中国人群比白种人群更高的菌斑指数得分来解释。
