久性を高めるための歯面清掃剤に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention cleans the enamel or dentin surface on which a cavity or abutment tooth has been formed using a cutting or grinding tool, thereby cleaning the tooth surface and the dental restoration. This invention relates to a tooth surface cleaning agent for increasing adhesive strength and durability.

ている。[Prior Art and Problems to be Solved by the Invention] In dental treatment, a method of adhesively fixing a dental restoration to a tooth using an acrylic resin adhesive is now widely used. However, this method requires etching the enamel or dentin surface of the adherend with an aqueous acid solution such as phosphoric acid or citric acid as a pretreatment for adhesion.

有効であり、かつ象牙質に対する作用が穏和な歯面清掃
剤を提供することにある。However, acid etching on the dentin surface causes pulp stimulation due to expansion of dentinal tubules and increased dentin permeability.
There is also concern about weakening of dentin collagen. Therefore, an object of the present invention is to provide a tooth surface cleaning agent that is effective in cleaning enamel and dentin and has a mild effect on dentin.
［課題を解決するための手段］

脂は粉末状で用いられ、その粒径は１５０メツシユ（約
１００μｓ）以下が好ましい。As the cation exchange resin, polystyrene-based gel type strongly acidic cation exchange resin, polystyrene-based macroporous type strongly acidic cation exchange resin, phenol-based strongly acidic cation exchange resin, etc. are preferably used. These exchange resins are used in powder form, and the particle size is preferably 150 meshes (about 100 μs) or less.
該陽イオン交換樹脂粉末を水中に分散させて懸濁液とす

The addition of dirosyl prevents the cation exchange resin powder from settling, eliminates the need for shaking or stirring the suspension during use, and also gels the suspension to improve its applicability to teeth.

Conventional acid aqueous solution type cleaning agent (pi11-3
) and is a safe cleaning agent for dentin and pulp. For clinical use, apply this cleaning agent to the enamel or dentin surface for at least 10 seconds, preferably 30 seconds.
It is left in contact with the tooth surface for more than a second and then removed by washing with water. As a result of this treatment, the cutting or grinding marks that occurred during cavity formation or abutment tooth formation disappear in the enamel, the enamel trabeculae are selectively etched, and the fine structure of the enamel is exposed. Afterwards, the smear layer and dentinal plug are removed from the dentin, and the dentinal tubules are opened.

Therefore, it is useful as a highly safe cleaning agent in place of conventional tooth surface cleaning agents containing an aqueous acid solution as a main component in many cases of dental treatment requiring tooth surface cleaning.
