age and prevalence of porphyromonas gingivalis in children.the acquisition of porphyromonas gingivalis was examined in a cross-sectional study of 198 subjects from 0 to 18 years of age using a pcr-based assay. p. gingivalis was detected in the oral cavities of 37% of subjects and at similar frequencies among subjects of all ages. these data indicate that p. gingivalis may be acquired in the first days of life.19968818903
prevalence of porphyromonas gingivalis and periodontal health status.periodontitis is a common, progressive disease that eventually affects the majority of the population. the local destruction of periodontitis is believed to result from a bacterial infection of the gingival sulcus, and several clinical studies have provided evidence to implicate porphyromonas gingivalis. if p. gingivalis is a periodontal pathogen, it would be expected to be present in most subjects with disease and rarely detected in subjects with good periodontal health. however, in most previo ...19989774572
acquisition and colonization stability of actinobacillus actinomycetemcomitans and porphyromonas gingivalis in children.the presence of porphyromonas gingivalis has been shown to be a risk factor for periodontitis in adults, and actinobacillus actinomycetemcomitans has been implicated as a pathogen in early-onset periodontitis. both species have been shown to establish stable colonization in adults. in cross-sectional studies, both a. actinomycetemcomitans and p. gingivalis have been detected in over one-third of apparently healthy children. information on the stability of colonization with these organisms in chi ...200010699021
