Abstract
AIM: In the current study, Porphyromonas gingivalis was identified in chronic periodontitis patients and healthy subjects by polymerase chain reaction (PCR) and its presence correlated with the severity of clinical periodontal parameters. MATERIALS AND METHODS: Subgingival plaque samples were collected with sterile curette and subjected to deoxyribonucleic acid (DNA) extraction and subsequent PCR for detection of P. gingivalis. RESULTS: Porphyromonas gingivalis was detected in 60% of patients of group II (pocket depth up to 5 mm), and in 93.33% of patients of group III (pocket depth more than 5 mm). One periodontally healthy subject in group I (probing depth < 3 mm) showed the presence of P. gingivalis. CONCLUSION: Detection frequency of bacterium increased significantly with increase in probing pocket depth (PPD), loss of attachment (LOA), and gingival index (GI). CLINICAL SIGNIFICANCE: Porphyromonas gingivalis is strongly associated with chronic periodontitis and its detection frequency positively correlates with the severity of periodontal destruction.
