    • PROBLEM TO BE SOLVED: To provide a detecting liquid capable of simply and accurately detecting dental caries-infected part while suppressing dental caries by sterilizing the infected dentin or carrying out bacteriostasis of the infected dentin and having (recalcifying) effect of suppressing production of dental plaque which becomes a cause of dental caries/periodontal diseases of infected dentin part and the circumference of the dentin part and strengthening tooth quality in the applied part with passage of time.
      SOLUTION: The dental caries-detecting liquid is composed of (A) a pigment or dye for imparting color capable of identifying the dental caries-infected part from the dentin by dyeing the dental caries-infected part, (B) a compound having dental caries-suppressing effect and (C) an aqueous solvent capable of dissolving or dispersing the components (A) and (B). In the dental caries-detecting liquid, at least one kind of pigment selected from a group consisting of fluorescein sodium, basic fuchsin and acid red is contained as at least the component (A) or a polyphenol containing a fluoride compound and/or a chroman skeleton-based substituent group is contained as the component (B).

    • PROBLEM TO BE SOLVED: To provide a dental adhesive material, or more in details, to provide the dental adhesive material capable of bonding an abutment and an upper part structure together in a dental implant and, when separating the upper part structure as necessary, disassembling them without damaging the abutment and the upper part structure. SOLUTION: This dental adhesive material contains a copolymer (a) formed by copolymerizing a compound having unsaturated double bond and containing a long-chain alkyl(met)acrylate monomer (a1) with the number of carbons in the alkyl group of 5 or more and a short-chain alkyl(met)acrylate monomer (a2) with the number of carbons in the alkyl group of 1-4. The dental adhesive material is so formed that the glass transition temperature of the copolymer is -35°C-35°C, the weight-average molecular weight is 20,000-200,000, and the melting point is within the range of 40-60°C. The copolymer (a) contained in the dental adhesive material has the melting point within the range of 40-60°C and can easily bond the abutment and the upper part structure together by sticking them in its melted state.
