Abstract

Periodontal disease is an infection caused by the accumulation of bacteria in plaque under the gums. Aggressive periodontitis is a disease that destroys periodontal tissue, causing clinical attachment of loss and rapid alveolar bone loss, less corresponding to local inflammation. The disease is common in healthy young people with a low incidence. Periodontal tissues has many causes, including some specific pathogenic bacteria such as Aggregatibacter  actynomycestemcomytan, porphymonas gingivalis, parvimonas micra.... Identification of some bacteria causing periodontal disease that Generalized aggressive periodontitis in a group of patients aged 20 - 45 years, determined by anaerobic bacterial culture and polymeraase chain reaction (PCR) techniques. All 35 patients were diagnosed with Generalized aggressive periodontitis and were sampled for subgingival plaque that was detected by anaerobic culture and PCR techniques to identify some pathogenic bacteria. The percentage of bacteria identified after performing anaerobic culture, Realtime polymeraase chain reaction technique: Aggregatibacter actinomycetemcomitans 11,3%, Porphymonas gingivalis 0%, F.nucleatum 0%, Tannerella forsythia 5,7%, Parvimonas micra 11,4%, Veillonella parvula 45,7%, Campylobacter showae 5,7%, Prevotella intermedia 22,9%, Trenponema dencota 11,4%. There was little association between the prevalence of anaerobic bacteria and oral hygiene status and a high degree of association in the severity of the patient's disease.
