[Comparative study of the plaque-removing effect of oral irrigation]

The authors in case of 10-10 persons compared the plaque removal effectiveness of toothbrush (II. group), the "Héviz" type mouth shower (I. group) and "Hexoral" (III. group) during two weeks period. In the IV. group all oral hygiene is ceased. According to the result they found less amount of plaque in the II. group and the greatest in the IV. group. The plaque removal effect of the mouth shower (II. group) was not much worse than the "Hexoral" (III. group). It means that mouth shower is ineffective alone to maintain good oral hygiene.
