The invention relates to a method and a preparation for cleaning tooth root surfaces and surrounding tissue (periodontal pockets). The preparation is a two-component liquid of the type that has previously been used for chemical-mechanical treatment of carious lesion. The active component in the liquid is a hypochlorite, preferably sodium hypochlorite, and the other component in the liquid is a component which reduces the aggressiveness of the hypochlorite on healthy tissue and which also increases the viscosity of the liquid. The preparation is applied on the tooth root surface in question by means of a brush or an applicator instrument. After 10-15 seconds the root surface is cleaned by means of a scraping instrument.

Method and a preparation for cleaning tooth root surfaces and surrounding tissue

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 &plus;1, Cl(&plus;1), which chloride has a somewhat lower reactivity than sodium hypochlorite and then also a somewhat reduced dissolving effect on the carious substance.

Preparation for dental treatment

A dental instrument is provided for removing caries attacked dentine in connection with chemical-mechanical treatment of caries by means of a caries-dissolving solution applied to the caries for loosening the caries tooth substance. The instrument comprises a tool head with a number of scraping edges or bristles for scraping away the loosened caries tooth substance. In the spacings formed therebetween drops of the gel solution used for the chemical-mechanical treatment can be carried (transported) up to the tooth treatment site. The instrument is power-driven in order to provide the tool head with a predetermined scraping motion.

Dental instrument

The invention relates to a preparation for use in chemical-mechanical treatment of caries in the form of a two-component caries dissolving liquid in which one of the components consists of sodium hypochlorite and the other component of amino acids, preferably three amino-acids with different charge states; one neutral, one with a negative net charge and one with a positive net charge. A viscosity increasing substance in the form of 3% carboxy methyl cellulose, or any other polysaccharide, as well as a coloring agent, 0.04% Erythrosin, which is able to interact with carious tooth substance has been added to the amino acid component. This means that less liquid is spent, the liquid becomes easier to control and handle and the suspended material becomes more visible.

The invention relates to a preparation for use in chemical-mechanical treatment of caries in the form of a two-component caries dissolving liquid in which one of the components consists of sodium hypochlorite and the other component of a substance with the ability to reduce the aggressive influence of sodium hypochlorite on mucous membranes. The other component is a gel component which consists of a gel substance without any amino acids or a gel substance mixed with one or more amino acids.
