The tooth surface treating agent imparts strong adhesion to the enamel and dentin of teeth through simultaneous treatment thereof. The invention is mainly intended for use in the field of dentistry, but is also applicable as a treating agent for vital hard tissues in such fields as surgery, and orthopaedic or plastic surgery. ## Claims ### Claim 1 A tooth surface treating agent, comprising: 0.01 to 30% by weight of a polymerization catalyst selected from the group consisting of ascorbic acids, a barbituric acid derivative, an organic peroxide, sulfinic acids, salts thereof and photo polymerization catalysts and a mixture thereof, 1 to 70% by weight of an acidic compound which is nonpolymerizable and selected from the group consisting of phosphoric acid, tartaric acid, maleic acid, citric acid, ferric chloride, and polyacrylic acid, or a mixture thereof, and 10 to 98% by weight of water, the tooth surface treating agent not containing a monomer and being suitable for cleaning tooth surface. ### Claim 2 (depends on 1) A tooth surface treating agent as set forth in claim 1, which may contain a solvent such as ethyl alcohol or acetone. ### Claim 3 (depends on 1) A tooth surface treating agent as set forth in claim 1, which may contain an oxidation inhibitor and/or a viscosity modifier. ### Claim 4 (depends on 1) A tooth surface treating agent of claim 1, comprising: 0.1 to 25% by weight of a polymerization catalyst, 1 to 35% by weight of an acidic compound, and balance of water, on the basis of the total amount of the polymerization catalyst, acidic compound and water, and being suitable for cleaning tooth surface. ### Claim 5 (depends on 1) A tooth surface treating agent as set forth in claim 1, wherein the polymerization catalyst is selected from the group consisting of L-ascorbic acid, 1, 3, 5-trimethylbarbituric acid, 1-cyclohexyl-5-ethylbarbituric acid, 5-butylbarbituric acid, 1-benzyl-5-phenylbarbituric acid, 1-butylperoxy maleic acid, succinic acid peroxide, t-butyl hydroperoxide, benzenesulfinic acid sodium salt, p-toluenesulfinic acid sodium salt, and camphorquinone and mixtures thereof. ### Claim 6 (depends on 2) A tooth surface treating agent as set forth in claim 2, wherein the polymerization catalyst is selected from the group consisting of L-ascorbic acid, 1, 3, 5-trimethylbarbituric acid, 1-cyclohexyl-5-ethylbarbituric acid, 5-butylbarbituric acid, 1-benzyl-5-phenylbarbituric acid, 1-butylperoxy maleic acid, succinic acid peroxide, t-butyl hydroperoxide, benzenesulfinic acid sodium salt, p-toluenesulfinic acid sodium salt, and camphorquinone and mixtures thereof. ### Claim 7 (depends on 2) A tooth surface treating agent as set forth in claim 2, which may contain a solvent such as ethyl alcohol or acetone. ### Claim 8 (depends on 2) A tooth surface treating agent as set forth in claim 2, which may contain an oxidation inhibitor and/or a viscosity modifier. ### Claim 9 (depends on 1) A tooth surface treating agent as set forth in claim 1, wherein the polymerization catalyst comprises L-ascorbic acid, 1, 3, 5-trimethylbarbituric acid, 1-cyclohexyl-5-ethylbarbituric acid, 5-butylbarbituric acid, 1-benzyl-5-phenylbarbituric acid, 1-butylperoxy maleic acid, succinic acid peroxide, t-butyl hydroperoxide, benzenesulfinic acid sodium salt, p-toluenesulfinic acid sodium salt, and camphorquinone, or a mixture thereof. ### Claim 10 (depends on 1) A tooth surface treating agent as set forth in claim 1, which may contain a solvent such as ethyl alcohol or acetone. ### Claim 11 (depends on 1) A tooth surface treating agent as set forth in claim 1, which may contain an oxidation inhibitor and/or a viscosity modifier.
