Un agent nettoyant est acheminé sous forme liquide et/ou gazeuse jusqu'à une zone fermée vers l'extérieur qui entoure toutes les dents d'une mâchoire supérieure et/ou inférieure et est soumis à des ultrasons. La durée du traitement ultrasonore, l'amplitude, la fréquence et la puissance ultrasonores sont réglées à des niveaux inférieurs à ceux risquant d'altérer les cellules/les tissus et la substance dure ou le segment dentaire. Le nettoyant utilisé est un liquide adapté à la plaque dentaire et qui contient des additifs dissolvant ladite plaque ou renforçant l'absorption des ultrasons, des substances tensioactives et/ou des inhibiteurs de catalase et/ou de peroxydase et/ou des composés sous forme micromoléculaire, ainsi que le cas échéant des substances protectrices, qui enrichissent la dent en tant qu'additifs.
