HUBUNGAN KEDALAMAN POKET DENGAN JUMLAH BAKTERI BLACK-PIGMENTED ANAEROB PADA PENDERITA AGGRESSIVE PERIODONTITIS

Abstract

The progression of aggressive periodontitis is associated with increases in the levels of several anaerobes. Certain oral anaerobic gram-negative bacilli that produce a black pigment on blood agar have been found to be associated with detructive forms of inflammatory periodontal disease.In human periodontal pockets, the localization or distribution of bacteria relate to pathological periodontal dectruction. In this study, we investigated the correlation between clinical indicator (probing depth) and the count black-pigmented anaerobes bacteria on the aggressive periodontitis patients. Ginginal crevicular fluid sample were taken from 12 site in aggessive periodontitis patient using sterile paper points for 30 seconds. The sample were placed in transport fluid and tranferred to the microbiological laboratory. Following measurement of each pocket, paper points were transported to cultured on blood agar, and colony forming units were determined for black-pigmented colonies. The result showed that there was correlation between pocket depth with the count og black-pigmented anaerobic bacteria (r= 0.895, p< 0.05). Total black-pigmented anaerobes bacteria viable counts 3,93 x 102 cfu/ml for deeper pockets when compared to pockets 0-3 mm. These findings suggest that black-pigmented anaerobes bacteria positive correlated with the clinical parameter like probing depth in the aggressive periodontitis patient.
