Dental conditioning composition

Abstract

An object of the present invention is to provide a dental conditioning composition that enhances the adhesiveness of any dental material for a tooth surface by suppressing any excessive demineralization for the tooth surface and improving the polymerization activity of a dental adhesive composition by causing a polymerization catalyst included in the dental conditioning composition of the present invention to remain on the tooth surface. The dental conditioning composition having a gel character, that includes a polymerization catalyst, an acidic compound, water, and a thickening agent, and whose pH (the hydrogen ion exponent) is in a range from 0.1 to 0.9.

Description

technical field [0001] The present invention relates to the use of a dental adhesive composition for orthodontic materials, pit and fissure sealing materials, restorative materials, crown materials, prosthetic materials, core build-up materials, root canal materials, etc. A dental conditioning composition used for tooth surface treatment before applying a dental adhesive composition when a dental material is bonded to the tooth surface. Specifically, it relates to unground tooth enamel to be bonded when bonding orthodontic materials, pit and fissure sealing materials, etc., or to bonding restorative materials, crown materials, prosthetic materials, post-core construction materials, root A dental conditioning composition that can be used for both enamel and dentin after cavity formation, such as a tube material, to be adhered. In further detail, it relates to a dental conditioning composition, characterized in that the tooth surface (unground tooth enamel, or tooth enamel and ...

Problems solved by technology

However, this technique has the following problem: Since the acidic aqueous solution with low viscosity (viscidity) with high permeability to dentin is used, the decalcification site is not limited to the surface layer of dentin but reaches deep, and as a result, damage to the pulp, etc., is likely to occur. damage

However, the invention of Patent Document 4, like the invention of Patent Document 3, has the following problems: since it is a low-viscosity treatment agent with high permeability to dentin, the decalcified site is not limited to the surface layer of the dentin but reaches the deep part. As a result, it is easy to cause damage to the pulp, etc.

In addition, in the invention of Patent Document 4, the adhesiveness to either dentin or enamel is significantly lowered depending on the type of polymerization catalyst used.
