The invention relates to a dental adhesive film for the local treatment of teeth by remineralisation. Said film consists of a support material that adheres to the teeth and is soluble or swellable in water and of active ingredients stored in said material. The film contains as its active ingredient a fine-particle calcium salt that is poorly soluble in water, selected from the group containing phosphates, fluorides, fluorophosphates and mixtures thereof, preferably hydroxyl apatite and/or fluoroapatite, with an average particle fineness of between 10 and 300 nm (nanometers). In addition, the support material preferably contains a protein component, preferably in the form of a fine-particle composite material consisting of a calcium salt that is poorly soluble in water and protein components.
L'invention concerne une feuille adhésive dentaire destinée au traitement local de reminéralisation dentaire. Cette feuille adhésive est constituée d'un matériau support, soluble ou gonflant dans l'eau et adhérant à la dent, ainsi que de substances actives contenues dans ledit matériau. Selon l'invention, la substance active est un sel de calcium en fines particules, difficilement soluble dans l'eau, sélectionné dans le groupe comprenant des phosphates, des fluorures, des fluorophosphates et leurs mélanges, de préférence l'hydroxylapatite et/ou la fluorapatite de granulométrie particulaire moyenne variant entre 10 et 300 nm (nanomètres). En outre, le matériau support comporte de préférence un composant protéique, notamment sous forme de fin matériau composite alliant du sel de calcium difficilement soluble dans l'eau à un composant protéique.
