[The effect of repeated spray treatment on the bacterial flora of the mouth cavity in patients with periodontal disease].

The effect of a four times repeated spray application on the clinical picture and the number of oral aerobic micro-organisms has been studied on 21 patients with periodontal disease during a stay at hospital. Comparative studies corroborated the effect of antiseptics added to the spray. The reduction of the number of micro-organisms did not continue during the four days of application so that there was a discrepancy between the clinical picture and the microbiological findings. Possible causes of this fact are indicated in the discussion.
