Comparison of 5 Major Periodontopathic Bacteria in Aggressive and Chronic Periodontitis Patients: Using Anaerobic Culturing Technique.

Jyothi, L.; Tirumal Rao

Aim: Specific bacterium or a group of bacteria are found to be responsible for causing periodontal destruction and are associated with specific forms of disease. This study was carried out to identify 5 major periodontopathic bacteria in the subgingival bacterial sample of plaque of patients with aggressive (AgP) and chronic generalized periodontitis (CGP). Material and methods: The study was carried out in 40 patients divided into 2 groups- aggressive and chronic periodontitis. Pooled subgingival plaque samples were obtained with a sterile curette from the deepest pocket in each quadrant and transported to the laboratory for species identification using anaerobic culturing. Results: P.gingivalis, Pintermedia, Fnucleatuin and T.forsythus were isoloted at a greater rate in CGP thanAgP. Aactinoinyce- teincoinitans was most prevalent and isolated at a greater frequency from LAgP. However A.a could not be isolated from any subjects with CGP. Statistical analysis of the data showed a significant difference between CGP and LAgP when mean counts of the bacteria was considered. Conclusion: Not much difference in the specificity of major periodontopathic bacteria was found in CGP and GAgP. Identification of microbiota in the subgingival environment alone could not differentiate between different periodontal diseases. Further studies are required to identify particular strains of these periodontopathic bacteriathat are responsible for tissue destruction.
