Patent

CA 2391220

The present invention relates to oral composition comprising a polymeric surface active agent wherein the oral composition provides surface conditioning effects on a subject's teeth and/or oral mucosa. The surface conditioning effects include (a) increased hydrophilic character of oral surfaces as measured by a decrease in water contact angles or an increase in anionic surface charge and surface charge density and (b) decreased pellicle film thickness. The present invention also relates to methods of providing surface conditioning effects to a subject's tooth and mucosal surfaces and methods of preventing and controlling tartar and tooth staining by administering to the subject an oral composition comprising a polymeric surface active agent.

L'invention concerne une composition orale renfermant un agent polymère actif pour le traitement de surface sur les dents et/ou la muqueuse buccale. Les effets induits sont les suivants: (a) augmentation du caractère hydrophile des surfaces buccales mesurée d'après la diminution des angles de contact avec l'eau ou d'après un accroissement de la charge de surface anionique et de la densité de charge de surface, et (b) diminution de l'épaisseur de pellicule sur les surfaces. L'invention concerne en outre des procédés visant à assurer les effets de traitement de surface susmentionnés, sur les dents et les surfaces de muqueuse, ainsi que des procédés relatifs à la prévention et au contrôle du tartre et des colorations dentaires par l'administration d'une composition orale renfermant un agent polymère actif pour le traitement de surface.
