  • Preparation for dental treatment
    Patent number: 6572842
    Abstract: The invention relates to a preparation for chemical-mechanical treatment of caries by means of a caries-dissolving two-component liquid. One of the components is an active, caries dissolving component and the other a component which reduces the aggressiveness of the active component to mucous membranes. The active component is a chloride compound comprising active chlorine, i.e. chlorine having a charge state of +1, Cl(+1), which chloride has a somewhat lower reactivity than sodium hypochlorite and then also a somewhat reduced dissolving effect on the carious substance.
