[Nitrate reductase activity of the oral fluids in periodontitis].
In patients with parodontitis varying in severity, nitrites content and nitrate reductase activity were measured in the oral and gingival fluids (OF, GF). In patients, as compared to control subjects, OF displayed a tendency to reduce nitrates concentration which was lowered fourfold in exacerbations. Nitrate reductase activity was distinctly reduced in remissions of light and mild parodintitis, and increased in exacerbations. GF showed a low nitrite content with its nitrate reductase activity varying from 0 to 1.66 mumol/min per 1 ml. These levels were not different in patients and control group. The data indicate different states of oral homeostasis in parodontitis varying in severity.
