Abstract
Abstract This invention relates to a method inhibiting the formation of dental plaque. This invention has identified a number of compounds (e.g. allyl isothiocyanate, uranine, obtusastyrene, citral, citronellol, nerol and geraniol) which are effective as antimicrobial agents against cariogenic streptococci and which when topically applied to the teeth would be effective for use in oral preparations as a means to reduce dental plaque.
