Abstract

La présente invention concerne un système de soin buccal qui quantifie la quantité de plaque sur la base des valeurs de pixel obtenues en soumettant la capture des données d'image d'une cavité buccale d'un utilisateur au traitement d'image, et qui surimpose et affiche les données quantifiées de quantité de plaque sur les données d'image capturées des dents à l'intérieur de la cavité buccale pour permettre à l'utilisateur de reconnaître, de manière exacte et avec précision, la quantité de plaque accumulée sur les dents à l'intérieur de la cavité buccale de l'utilisateur et le site d'accumulation de plaque. Ce système de soin buccal est caractérisé en ce qu'il comprend une brosse à dents de détection de plaque dotée d'un moyen d'imagerie susceptible de capturer une image intrabuccale d'un utilisateur, soumettant l'image intrabuccale de l'utilisateur capturée par la brosse à dents de détection de plaque au premier traitement d'image et second traitement d'image pour quantifier la plaque et les gencives sur la base des valeurs de pixel classées en plaque, dents, gencives et similaires, et pour afficher les résultats du premier traitement d'image et du second traitement d'image comme données d'image sur un moyen d'affichage pour permettre à l'utilisateur de reconnaître l'état des gencives et de brosser les dents tout en reconnaissant le site et la quantité d'accumulation de plaque sur les dents à l'intérieur de la cavité buccale.
