Evaluation of Actinobacilius Actinomycet-em Comitans Presence in Sub gingival Flora of Rapidly Progressive Periodontals Patients

One of the special kinds of periodontal disease is rapidly progressive periodontitis (RPP). This"nform of periodontitis is an aggressive disease, which results in bone destruction and loss of periodontal"nattachment 4 to 5 times more than adult periodontitis or slowly progressive periodontitis. The purpose of"nthis study was to investigate the presence of Actinobacilius actinomyct-em comitans (Aa) in RPP"npatients. A total number of sixty samples was collected from 15 patients with RPP and cultured in"nanaerobic conditions. Results showed the presence of Aa in 13 patients (86.7%), while 29 samples were"nAa positive (48.3%). Two of the RPP patients (13.3%) were Aa negative even after two times bacterial"nculturing
