Research Abstract

The monoclonal antibodies effective for the detection of P. gingivalis and T. forsythia localized in tissue specimens were prepared. Periodontal pathogen was detected in diseased gingival tissue and atherosclerosis sample by immunohistochemistry. Oral and vascular samples of Buerger disease patients in Sri Lanka were detected periodontal pathogens by polymerase chain reaction method. The existence of periodontal pathogens in formalin-fixed and paraffin embedded lymph nodes proximal to oral cavity was examined from patients with histories of head and neck cancer. These bacteria invaded in gingival tissues might translocate peripheral arteries via lymph nodes.
