- Abstract
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 deter-j mined along with an evaluation for microorganisms 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, <em>Fusobacterium</em> spp. and dark-pigmented <em>Bacteroides</em> species, while the Caucasian group had higher mean proportions of cocci, total <em>Actinomyces</em> spp., <em>A. viscosus</em> and total <em>Streptococcus</em> spp. in supragingival plaque. The microbial differences observed in supragingival plaque may he explained at least in part, if not totally, by the higher plaque index scores of the Chinese versus Caucasian population groups.
