Abstract:

Destructive periodontal diseases are infectious disorders, but the specific mechanisms by which tooth-supportive tissue is lost remain obscure. This chapter proposes an infectious disease model for severe periodontitis in which herpesviral-bacterial interactions assume a major etiopathogenic role. Herpesviruses, especially cytomegalovirus (HCMV), Epstein-Barr virus type 1 (EBV-1), and HCMV/EBV-1 dual infection, have recently been identified in most of the advanced periodontitis lesions of children, adolescents, and adults. Herpes simplex virus (HSV) type 1, human herpesvirus 6 (HHV-6), HHV-7, and HHV-8 (individuals infected with the human immunodeficiency virus (HIV)) can also be detected in some periodontitis lesions. Evidence suggests that herpesvirus-infected periodontitis lesions harbor elevated levels of periodontopathic bacteria, including , and . Conceivably, periodontal active herpesvirus infection impairs periodontal defenses, thereby permitting subgingival overgrowth of periodontopathic bacteria. It is further hypothesized that gingival tissue plays a role in the maintenance of herpesvirus load in vivo and that the shedding of herpesviruses from periodontal sites during reactivation plays a role in virus transmission. Understanding the significance of herpesviruses in human periodontitis may allow for improved diagnosis and, ultimately, disease prevention.
