bleeding on probing differentially relates to bacterial profiles: the oral infections and vascular disease epidemiology study.various bacterial species are differentially prevalent in periodontal health, gingivitis or periodontitis. we tested the independent associations between three bacterial groupings and gingival inflammation in an epidemiological study.200818400025
analysis of site specific periodontal bacteria sampling schemes.a great deal of controversy has existed in the periodontal literature as to whether the site or the subject should be the unit of analysis. using the site as the unit of analysis assumes that observations of sites within the same subject are independent and ignores between subject variation. the purpose of this report is to evaluate the influence that the unit of analysis has on estimating the number of necessary site specific bacterial samples from each subject. the number of bacterial samples ...19921625150
serum igg antibody response to periodontal pathogens in minority populations: relationship to periodontal disease status and progression.differences in periodontal disease prevalence, severity, subgingival microflora and host immune response have been reported for various ethnic/racial groups, which implies that risk factors for destructive periodontal disease progression may also vary in these populations. as it is possible that these differences may be due to confounding variables other than ethnicity/race, we have measured serum igg antibody response to six periodontal pathogens, and compared these data with microbiological, c ...200212009183
prevalence and risk indicators for destructive periodontal diseases in 3 urban american minority populations.destructive periodontal diseases have been reported disproportionately more prevalent and severe in african-americans relative to other american populations. differences in subgingival microbiota and host immune response have also been reported for african-americans, implying that risk factors for disease progression may also differ for these populations. since it is not clear whether these differences are truly genetic or due to confounding variables such as social economic status, we examined ...200111350519
