To provide a fit checking material composition for dental use which facilitates checking of a fitting state.SOLUTION: Provided is a fit checking material composition for dental use containing a first paste and a second paste, wherein the consistency at 23°C of the mixed product 35 seconds after mixing the first paste and the second paste is 37 to 43 mm.SELECTED DRAWING: None

A glass composition includes gadolinium (Gd), cesium (Cs), or both; and silicon (Si). In the glass composition, in terms of respective oxides thereof, a total content of a gadolinium oxide and a cesium oxide is 1% by mass or more, and a content of a silicon oxide is 30% by mass or more.

The present disclosure relates to a plaque disclosing composition containing riboflavin 5-phosphate sodium, a method for disclosing a plaque, wherein the plaque is an acquired pellicle, and a method for collecting and analyzing an information about the amount and characteristics of dental plaque by analyzing the color and intensity of fluorescence emitted by riboflavin 5-phosphate sodium for effective treatment of dental plaque even at an early stage.

A phosphorous compound such as STMP is used as a cross-linking agent while making a starch nanoparticle in an emulsion process. Negative charge of the nanoparticle is reduced or reversed by adding cations and / or cationizing the starch optionally while forming the nanoparticles. Anionic active agents, such as fluoride or fluorescein, are optionally incorporated into the nanoparticle during the formation process. For example, a fluoride salt can also be used, which promotes the crosslinking reaction while also providing fluoride in the nanoparticle. The retention of both calcium and fluoride in the nanoparticle is improved when both salts are used. Alternatively, the nanoparticle may be used without added calcium and / or fluoride. The nanoparticles may be useful for tooth remineralization, the treatment of dentinal hypersensitivity, to treat caries, or as a diagnostic agent to locate carious lesions.

The disclosure is directed to compositions and methods related to colorimetric detection for dental uses (e.g., detecting the presence or absence of a dental caries, and / or cavity or cavities, or precursor thereof), including a rapid unambiguous color indicator that allows for visualization by an unassisted eye based on a localized oral pH reading.

Compositions for reducing / eliminating aerosolization during dental / surgical irrigation procedures are set forth. One or more of the compositions herein can be provided in substantially similar concentrations to reduce / eliminate aerosolization.

To provide a glass composition that is superior in both X-ray contrast and aesthetic properties.SOLUTION: A glass composition includes: gadolinium (Gd) and / or cesium (Cs); and silicon (Si). The glass composition has a total content of gadolinium oxide and cesium oxide of 1 mass% or higher and a content of silicon oxide of 30 mass% or higher, in terms of oxide.SELECTED DRAWING: None

There is provided herein a thickened dental Caries Status Disclosing Solution comprising a water-based thickened silver fluoride composition comprising a thickening agent for use in the initial application of the thickened silver fluoride composition to a carious lesion followed by the subsequent application of a reducing agent solution for the visual analysis of the status of the carious lesion wherein the water-based thickened silver fluoride composition comprises nitric acid to stabilize the water-based silver fluoride composition. The thickened dental Caries Status Disclosing Solution can also be used to treat teeth that are sensitive to at least one of heat, cold, sweet, acid and tactile pressure to thereby reduce sensitivity.
