Abstract

VICTOR, Ligia Valéria et al. Periodontal profile and presence of periodontal pathogens in young African-Americans from Salvador, BA, Brazil. Braz. J. Microbiol. [online]. 2008, vol.39, n.2, pp. 226-232. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822008000200005.

This cross-sectional study evaluated the periodontal status and the presence of periodontopathogens in 132 young, black ethnic subjects who live in Salvador/Bahia-Brazil and have never smoked. Periodontal Probing Depth (PPD), Clinical Attachment Level (CAL), Plaque Index (PI) and Gingival Index (GI) were measured and analyzed by ANOVA and Wilcoxon tests (p<0.05) according to gender and age. The presence of A.actinomycetemcomitans, P.gingivalis, E.corrodens and F.nucleatum was determined by PCR and was analyzed by ANOVA, Wilcoxon, Student-t tests (p<0.05). Mean values of PPD and CAL were 2.18 and 1.0mm, respectively. Clinical parameters did not show differences between subjects of varying gender and age. The microbial prevalence was observed to be 95.45% for E.corrodens followed by F.nucleatum with 68.18%, A.actinomycetemcomitans with45.45% and P.gingivalis with 40.9%. An association between the presence of pathogens and gender and age was not observed (p<0.05). PPD, CAL and PI were not associated with P.gingivalis; however, GI appeared in higher frequencies among subjects without P.gingivalis. In this young, black ethnic, Brazilian population, a high percentage (96.96%) of subjects harbored at least one selected periodontal pathogen, but most subjects showed a healthy periodontal status. Further investigations are required to evaluate the actual influence of the presence of these bacterial species.
