[Effect of cetylpyridinium chloride on formation and metabolism of human dental plaque].

In this work, the Cepacol (cetylpyridinium chlorid) diluted 1:2, when used for mouthwashes three time a day decreased the "in situ" formation of human dental plaque, however it didn't decreased neither the plaque fermentation, nor the IEP synthesis by the plaque. When the Cepacol was used for treating the "in vitro" dental plaque in both 1:10 and 1:20 dilutions, decreased the fermentation and the IEP synthesis of the "in vitro" plaque.
