Viruses: Bystanders of Periodontal Disease

Bacterial etiology of periodontal disease is an established fact today. However, despite advances in the field of pharmacology with advent of newer and better antibiotics prevalence of the disease could not be abated. Moreover, unpredictable remissions and indefinite pattern in a single host force us to go back to the exact etiology of the disease. Present is a short review highlighting the role and plausible mechanisms by which viruses can affect the development of periodontal disease. This broadens our concept and will help establish a better treatment protocol for periodontal disease.
