Abstract
|
|
|
The present study evaluated the potential of a easy rapid test system for the detection of specific bacterial enzymatic activities in some periodontally defined populations. Most forms of periodontal disease are associated with the presence or
overgrowth of anaerobic species that would include Treponema denticola, Porphyromonas (Bacteroides) gingivalis and Bacteroides forsythus among the cultivable plaque species in that they hydrolyze the synthetic trypsin substrate,
benzoyl-DL-arginine-naphthylamide (BANA). In turn, BANA hydrolysis by the plaque can be associated with periodontal morbidity and with the presence of these BANA-positive organisms in the plaque. In this study, the results of BANA test were
compared
with plaque index and gingival index by means of canonical corelation analysis.
@ES The results were as follows:
@EN 1. As the BANA scores were very significantly related to plaque index (R=0.967, p<0.05), BANA hydrolytic bacteria were isolated in higher proportions from subgingival plaque according to increase in plaque index.
2. As the BANA scores were very significantly related to gingival index(R-0.943, P<0.05), BNAN hydrolytic bacteria were isolated in higher proportions from subgingival plaque according to increase in gingival index.
