These include approximately 700 species of bacteria, as well as viruses, fungi and protozoa. Periodontitis is a disease attributable to multiple infectious agents and interconnected cellular and humoral host immune responses.Even though viruses have been implicated in the etiology of several medical and dental disorders, little or no data are available on the possible involvement of human viruses in the pathogenesis of human periodontal disease.Hence Recent microbiological researches on periodontal disease have focused on the possible involvement of human viruses in the etiology and pathogenesis of destructive periodontal diseases.This book gives an insight into how virus has its potential role in developing periodontal disease.
