Abstract: A method for simply predicting the degree of inflammation of periodontal tissue such as an inflamed area (PISA or CAPRS value), and a device (e.g., a DNA chip) used for the method are provided. The method is a method for estimating a periodontal pocket inflammation area by detecting bacterial loads of two or more types of bacteria in saliva and using the obtained detection results as indexes, wherein bacteria to be detected include: a bacterium having a positive correlation between the bacterial load of the bacterium and the periodontal pocket inflammation area and a bacterium having a negative correlation between the bacterial load of the bacterium and the periodontal pocket inflammation area.

Abstract: A dripping container cover includes: a bottom part; a first pressing part; and a second pressing part including a face facing the first pressing part, wherein the above described face and a face of the first pressing part which faces the second pressing part are provided with projections, and wherein a distance between an end of each of the projections, the end being apart from the bottom part further than the other end, and the bottom part is at least a predetermined value and the projections are arranged within both outermost ranges of the storing part assuming that the storing part is divided into four in a width direction thereof or wherein the above distance is less than a predetermined value and the projections are arranged within central ranges of the storing part assuming that the storing part is divided into four in the width direction.

Abstract: Provided is a dental floss that keeps cleaning performance thereof on one hand, and that is easy to handle because of a high rigid portion thereof on the other hand. Dental floss includes: a floss part that is formed by twisting a plurality of filaments together but not tying up the filaments; and tied-up parts that are provided continuously with the floss part, and are formed by tying up the plurality of the filaments, wherein each of the tied-up parts is formed in such a manner that filaments are covered with a contour part in a cross section thereof.

Abstract: Production of precipitates during storage of a composition for dentifrice that contains silica can be suppressed on the composition. The composition for dentifrice includes water; silica; and calcium chloride.

Abstract: One embodiment of the present invention relates to a dental composition including a (meth)acrylate, an ultraviolet absorber, and a fluorescent agent, wherein the ultraviolet absorber has free of a maximum absorption wavelength in a range of greater than 320 nm and less than or equal to 500 nm.

Abstract: There is provided a method of producing a polymerizable composition that includes a first polymerizable monomer; and a second polymerizable monomer, a polymer of the second polymerizable monomer, or both, the second polymerizable monomer, the polymer of the second polymerizable monomer, or the both being dispersed in the first polymerizable monomer, the method of producing a polymerizable composition includes dissolving the first polymerizable monomer; the second polymerizable monomer, the polymer of the second polymerizable monomer, or the both in a solvent to obtain a solution in a first step; and evaporating the solvent from the solution in a second step, wherein the first polymerizable monomer is a liquid, and wherein the second polymerizable monomer is a solid.

Abstract: A packaging container includes a body part, a lid part integrally engaged with the body part, an inner lid positioned between the body part and the lid part, a stored item containing part opening from an engaged portion of the lid part that is engaged with the body part, and configured to contain a stored item, a chemical agent containing part opening from the engaged portion of the lid part that is engaged with the body part, the chemical agent containing part being formed separately from the stored item containing part, and a ventilation path in which the stored item containing part and the chemical agent containing part are in communication, the ventilation path being formed in an inner space defined by the first member and the second member.

Abstract: A method for designing dentures according to which artificial teeth can be easily and accurately attached to a denture base, which is designed and shaped by CAD/CAM, when the artificial teeth are arranged on the denture base is provided. The method for designing a denture (10) on a computer based on data on an intraoral shape comprises: creating data on a shape of a denture base (20) based on the intraoral shape (S22); creating data on a position of an artificial tooth (30) to be arranged on the denture base (S23); and creating data on a shape of an occlusal guide (40) that is tabular and has a recess part corresponding to a shape of the arranged artificial tooth in an occlusal surface side (S24).

Abstract: A dental material container includes a cylindrical body that stores a dental material including a pair of opposing primary surfaces, and a rotatable cap covering the body. The cap includes an internal space capable of housing the dental material. The body includes a pair of first holders that are formed on an inner surface of the body to movably hold the primary surfaces of the dental material; the cap includes a pair of second holders formed inside of the cap to movably hold the primary surfaces of the dental material. When the cap is rotated in the circumferential direction relative to the body, a continuous space where the dental material is movable is formed by the first and second holders, the dental material located closest to the opening in the body moves into the cap, and the dental material moved into the cap is housed in the cap.
