[Chemical control of dental plaque via rinsing solution "Antiplaque C". 2. Cytological and bacterioscopic studies]

Two groups of probands have been studied: experimental and control. After the clinically performed oral hygiene all probands stopped the brushing of the teeth for a 7-day period. The oral cavity was twice daily rinsed with 10 ml solution for 30 s--with "Antiplaque C" for the experimental and with placebo--for the control. All probands were taken bilateral probe-impressions according to Dzemileva, Stojanova and Popov in the area of 31 tooth, stained by crystal-violet and observed under light microscope and immersion. The cytological finding in the experimental group did not reveal an inflammatory process in the gingival sulcus whereas increased gingival exudate was established in the placebo group as well as intensified leukocyte migration and single erythrocytes (subclinical phase of inflammation). The bacterioscopic finding in the group, systematically used "Antiplaque C", was reduced to poor dental plaque, preserved "fresh" till the end of the 7-day period being predominantly coccoid-rod-like. In the placebo group the dental plaque "ages"--from coccoid-rod-like it turns into mainly fibril with multiple vibrios and spirillae. The cytological and bacterioscopic data objectivize the inhibitory effect of "Antiplaque C".
