Abstract: Provided is a liquid mouthwash that is capable of maintaining a bactericidal effect over a long period, and uses electrolyzed water that inhibits metal corrosion. The liquid mouthwash contains electrolyzed water having a positive oxidation-reduction potential, a menthol, an anionic surfactant, and a water-soluble organic solvent, and has a pH of 6 to 8. The electrolyzed water, and the menthol or one or more anionic surfactants are accommodated without coming into contact with each other, and are preferably used in a mixed state at the time of use.

Abstract: A dental polymerizable composition comprising (a) a fluorine compound comprising a chain polymer having a main chain comprising a monomer unit having a hydrophilic group, and terminal groups comprising a fluoroalkyl group at each of both ends of the main chain; (b) a polymerizable monomer; and (c) a polymerization initiator.

Abstract: Provided is a dental restoration having improved conformity and bonding to a foundation. A method for producing such a dental restoration and a porcelain paste for the dental restoration are also provided. The dental restoration includes a ceramic framework and a porcelain layer deposited at least on the inner surface of the ceramic framework for being bonded by a dental adhesive to the outer surface of an abutment tooth in the mouth. In one preferred embodiment, the ceramic framework is formed of a zirconium oxide ceramic. In another preferred embodiment, the inner surface of the porcelain layer is silane-coupling-treated.

Abstract: The present invention provides a method of evaluating the risk of possible caries and the device, system, and program of the same, which is useful for the subjects to keep their mouth conditions best by measuring the chemical properties of saliva samples collected from the mouths of subjects to allow for easy and sanitary evaluation of the risk of possible caries in a short time and to help the subjects accurately recognize their risk of possible caries and closely consult their dentist. In the present invention, saliva from the mouth of subject is collected, a given ratio of acid is added to the saliva, and the chemical property of the saliva is measured to evaluate the risk of possible caries base on the measured value.
