[Effect of chlorhexidine inthe form of an 0.2% solution and a 1% gel upon the gingiva and the state of oral hygiene of schoolchildren (author's transl)].

A double blind experiment made twice for two weeks was used to determine the effectiveness of chlorhexidine-containing preparations (0.2% solution, 1% gel) from the oral hygiene index, the sulcal bleeding index, and the rate of flow of sulcal fluid, with a total of 64 schoolchildren serving as subjects. The results of a longitudinal comparison confirmed the plaque-inhibiting effect of the chemotherapeutic agent, whereas inflammations of the gingiva were seen to be essentially unaffected. Short-time application of chlorhexidine is recommended as a supportive measure of oral hygiene to be taken in specific cases of indication.
