ABSTRACT
Purpose:
The objective of this study was to evaluate the prevalence of Porphyromonas gingivalis (Pg) and its filmA II genotype in a sample of Brazilian patients with generalized aggressive periodontitis (GAgP) and to correlate the presence of each pathogen/genotype eith clinical parameters.Methods:
We used polymerase chain reaction (PCR) to evaluate the presence of Pg and filmA II genotype in subgingival plaque samples collected from the deepest site of 45 Brazilian patients aged 15-40 years with GAgP and correlated findings with age and clinical parameters (plaque index, gingival bleeding index, probing depth and clinical attachment loss).Results:
Pg was identified in 64.4% patients. FilmA II genotype was present in 82.6% of Pg-positive patients. The presence of Pg and filmA II genotype was significantly associated with greater clinical attachment loss at the sampled periodontal site. Pg-positive patients were slightly older than Pg-negative patients.Conclusions:
Pg and filmA II genotype were highly prevalente in Brazilian patients with GAgP. Pg was more commonly observed in slightly older individuals and in sites with more clinical attachment loss. (AU)Key words
