A two-component dental bleaching system is provided wherein the components are adapted to be admixed and applied to the teeth from a dental bleaching tray. One component comprises a dental peroxide gel having a pH from about 4 to about 7 and the other component comprises an orally compatible alkaline gel having a pH from about 9 to about 13. The admixing of the components provides a dental bleaching gel having a pH from about 8,5 to about 11 to thereby increase the rate of release of active oxygen and accelerate the bleaching action.
Cette invention se rapporte à un système de blanchiment dentaire à deux composants, dans lequel les composants sont destinés à être mélangés et appliqués sur les dents à partir d'un baquet de blanchiment dentaire. L'un de ces composants contient un gel de peroxyde dentaire ayant un pH compris entre 4 environ et 7 environ, et l'autre composant contient un gel alcalin oralement compatible ayant un pH compris entre 9 environ et 13 environ. Le mélange de ces deux composants forme un gel de blanchiment dentaire ayant un pH compris entre 8,5 environ et 11 environ, afin d'augmenter la vitesse de libération de l'oxygène actif et d'accélérer l'action de blanchiment.
