Abstract |
: |
A randomized sample of sixty-six 12-16-year-old adolescents from 3 different locations in Egypt was selected to
share in this study. Pocket depth, Plaque-Index, and Gingival Index were recorded from 6 randomly selected sites in
each subject (a total of 396 sites). Subgingival plaque samples were subsequently collected from these sites and
processed by several assays. For cost reasons, in each pair of sites different assays were performed as follows: sites
No. 1, No.2 - BANA test for T. denticola, P. gingivalis, B. forsythus and screening of plaque samples with polyclonal
antibodies (ELISA system) for A. actinomycetemcomitans. Sites No.3, No.4 - detection ofyeasts by SAB agar. Sites
No.5, No.6 - detection of Entamoeba gingivalis by the Heidenhain iron hematoxylin modified technique. A total of
66% of the children had at least one site that bled upon probing, 42% exhibited at least one site with pocket depth >3
mm, and 79% exhibited a high Plaque Index, with the percent of sites affected being 30%, 12% and 41%.
respectively. In sites No.l, No.2 (N = 124), the BANA test assay and A. actinomycetemcomitans tested positive in
77% and 47% of the children accounting for 59% and 31% of the sites, respectively. In sites No.3, No.4 (N = 124),
yeasts were detected in 43% of the children and 29% of the sites. In sites No.5, No.6 (N = 124), Entamoeba
gingivalis was detected in 21% of the children and in 11% of [he sites. The risk for severe gingival inflammation
and/or increased probing depth was 1.5 and 5.2 times higher if a positive BANA test or A. actinomycetemcomitans
test was found in a particular site. No associations could be found for yeasts
and Entamoeba gingivalis. |
