RESUMO

The installation and progression of periodontal diseases are associated with risk factors in witch there are some bacterial species. The aim of this cross-sectional study was evaluate by PCR the prevalence of A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythensis e C. rectus in gingival sulcus and mucosa of tongue and bucca of children with 2 to five and six to 12 years old and adolescents with 13 to 18 years old. Associations of periodontal pathogens with age, gender and periodontal condition were realized. Children (2 - 5; 6 -12 years old) and adolescents (13 -18 years old) were included in this study. The periodontal condition was established by plaque index (IP), gingival index (IG), probing depth and attachment clinical level. On statistical analysis were used Qui-Squared test and Exact Fishers test for comparison of qualitative variables frequencies , t-Student for analyses of IP, Mann-Whitney tests for analyses of IG. The bacteria of major and minor prevalence were respectively C. rectus (94%) and P. gingivalis (2%), the last one was only observed in adolescents gingival sulcus. The youngest age group showed the lowest bacterial prevalence. Gender did not interfere on bacterial prevalence of population studied. We observed a worse clinical condition when periodontal parameters were associated with T. forsythensis e P. intermedia.
