The invention relates to a diagnostic apparatus with which diseased hard tissue, in particular carious dental tissue, can be examined through a small working channel, to see whether it can be made healthy again by remineralization. This diagnosis apparatus tightly (54) seals the working channel, produced in the tissue, from its environment, and places the cavity in the tissue under pressure, after which the pressurization is ended and a pressure drop is measured by means of a pressure measuring instrument (60). The speed of the drop in pressure is a measure of the extent of the changes to the diseased tissue. The invention also relates to a treatment device for supporting the remineralization or reinfiltration of diseased hard tissue and for preparing this, as well as to diagnosis and treatment agents and treatment substances.
L'invention concerne un appareil de diagnostic permettant d'examiner, à travers un petit canal de travail, du tissu dur malade, notamment du tissu dentaire carié, pour voir s'il peut être retransformé en tissu sain par reminéralisation. Cet appareil de diagnostic obture hermétiquement (54) vis-à-vis de l'environnement le canal de travail pratiqué dans le tissu et met sous pression la cavité tissulaire, la sollicitation en pression est ensuite supprimée et la chute de pression est mesurée par l'intermédiaire d'un manomètre (60). La vitesse de la chute de pression indique l'ampleur des modifications apportées au tissu malade. L'invention concerne également un appareil de traitement facilitant la reminéralisaation ou la ré-infiltration de tissu dur malade et permettant sa préparation à cet effet, ainsi que des moyens de diagnostic et de traitement et des substances thérapeutiques.
