PURPOSE:To enable identification of the dentin and the dental enamel by constituting a material for identifying the tooth substance of a high polymer material having a carboxyl group, org. titanate comp. and pH indicator having a discoloration region in 2-7pH. CONSTITUTION:A material for idensifying the tooth substance layer is constituted of a high polymer material having a carboxyl group, org. titanate compd. and pH indicator having a discoloration region in 2-7pH. The reagent component reacts with the dentin and enables discrimination of the dentin and the dental enamel when the reagent consisting of such specific compsn. is used. A method for mixing the high polymer material having a carboxyl group, org. titanate compd. and pH indicator in the presence of an org. solvent is most adequately used as a method for mixing these materials. Ethanol, ethyl acetate or aceton is adequately used as the org. solvent as said solvent is genrally low in b.p. and is easily removable. |
