Prevalence of periodontopathogens in a black Brazilian secluded community matched with a black urban population

Objective: To evaluate the prevalence of periodontopathogens according to periodontal profile in a black Brazilian secluded community matched with an urban black population. Participants: A total of 84 subjects were selected, 42 (mean age 25.7 sd 18.0 years) from a secluded community called Santo Antonio do Guapore (SAG) and 42 (mean age 25.4 sd 18.1 years) from an urban area of Sao Paulo State (SPT). Methods: Participants received clinical examinations as follows: periodontal pocket depth; clinical attachment loss; plaque and gingival indexes. After examination, the secluded population was classified as periodontal health (13), gingivitis (15) or periodontitis (14). Then, 182 urban volunteers were screened and 42 subjects were selected matched for the variables: periodontal diagnosis, age (±2 years) and gender. Samples were taken for microbial analysis. Genomic DNA for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Campylobacter rectus, Tannerella forsythia and Prevotella intermedia was provided by polymerase chain reaction. Results: Except for C. rectus, all pathogens were present in both groups with no statistically significant difference. In particular, C. rectus was more prevalent only in gingivitis subjects from the SPT group (p<0.05). A high frequency of periodontopathogens was related to the severity of periodontal disease. Conclusion: In general, the prevalence of the examined periodontopathogens in this study did not differ between a secluded black Brazilian population and an urban black population.

Key Words: periodontitis, ethnic groups, polymerase chain reaction, bacteria.
