Bacteriology of moderate (chronic) periodontitis in mature adult humans.

摘要: A total of 171 taxa was represented among 1,900 bacterial isolates from 60 samples sites affected with moderate periodontitis in 22 mature adult humans. The composition the subgingival sulcus flora statistically significantly different that adjacent supragingival and 14 people healthy gingiva, but not sulci severe 21 young human adults. floras shared many their predominant species, there were differences relative proportions some these species. Similar relationships found for seven treponemes cultured samples.
