Classification of periodontal lesions has always been a difficult and dynamic issue, due to constant addition of knowledge that enriches our understanding of periodontal pathophysiology. With current evidence from metagenomics, it is necessary to find the association of oral microbiota to periodontal lesions.
Current study is cross-sectional, and samples (subgingival plaque) were collected from 6 individuals classified in to 2 groups., Viz. Aggressive periodontitis and Chronic periodontitis. The study excluded patients who underwent Antibiotic therapy within the past 3 months, Pregnant women, systemically unhealthy individuals, tobacco(in any form) user and alcoholics. Metagenomic analysis was conducted on subgingival plaque and results were tabulated with respect to red complex bacteria.
It was observed that, red complex bacteria have not differed significantly between the chronic and aggressive periodontitis patients.
The new classification of periodontal lesions, 2017 is justified by classifying all microbial diseases in to one group as there is no evidence in metagenomics to separate them. But, the difference in clinical manifestation has to be further investigated to arrive at better treatment modalities.
