[Mouth and throat disinfectant preparation--dental aspects]

The oral fermentability of 10 mouth and throat disinfectant lozenges available in Switzerland were tested telemetrically. Because of their high sugar content all products produced immediate and long-lasting pH depressions in the interdental plaque except for a sugar-free preparation intended for diabetic patients. The cariogenic potential as well as the contraindication of such tablets in the treatment of infections of the oral mucosa, gingivitis, periodontitis or following dental surgery are shown.
