Abstract: The present research decided to study prevalence of Porphyromonas gingivalis and Bacteroides forsythus in chronic periodontitis patient by use of Multiplex PCR. The subgingival plaque samples from 61 patients suffering from chronic periodontitis with probing depth PD≥6 and 40 healthy controls were collected by sterile curette. In this study we used two species-specific Forward primers in combination with a single Reverse primer. These primers target variable and conserved region of 16S rRNA gene, respectively. The study included 61 patients (34 women, 27 men; 24-69 years of age; mean 43) and 40 periodontally healthy controls (22 Women, 18 men, 21-69 years in age; mean 41.35%). Porphyromonas gingivalis was detected in 51 samples (83.61%) and 16 samples (40%) of chronic periodontitis patients and healthy subjects, respectively and Bacteroides forsythus was detected in 32 samples (52.50%) of chronic periodontitis patients and was not detected in any sample from healthy persons. We set up Multiplex PCR in order to detect P. gingivalis and B. forsythus simultaneously. The present data suggest that P. gingivalis is a more important cofactor in etiology of chronic periodontitis. Further studies are needed to determine spectrum of pathogenicity of the disease and effective management of diagnosis and treatment in order to decrease the risk of periodontic complicates such as systemic infection.
