The present invention addresses the problem of providing an auxiliary instrument for dental treatment capable of being easily removed from a tooth restored while hardly causing pain to a patient when removing the auxiliary instrument for dental treatment after curing a curable composition for tooth restoration. One aspect for solving the above problem is an auxiliary instrument for dental treatment, the auxiliary instrument having a body part having a recessed opening part capable of accommodating at least a portion required to be restored of a tooth restored of a patient, wherein: a portion at least accommodating the portion required to be restored has an inner surface shape corresponding to a preliminarily designed outer surface shape of the portion required to be restored of the tooth after restoration; in a state in which the body part is elastically deformed and attached to the tooth restored, a cavity is formed by the inner surface shape and the outer surface shape of the tooth restored; the auxiliary instrument for dental treatment restores the tooth restored by irradiating a dental photocurable composition introduced into the cavity with light in a state of being attached to the tooth restored to cure the dental photocurable composition; and a resin material having a tensile elongation in accordance with JIS K6251 of 10%-60% is used.

To improve the storage stability of paste properties of "a dental shade-matching confirmation material which comprises a polyhydric alcohol (a), water (b) and a filler (c) each contained at a predetermined ratio, and optionally blended with a pigment (d) to adjust the shade to a predetermined color tone", which is known to have a paste property similar to that of a dental cement and to exhibit excellent removability by water washing after trial fitting work.SOLUTION: In the dental shade-matching confirmation material, an inorganic salt (e) having a solubility in water of 10 g or more is blended, where the content ratio of (a) in a liquid component composed of (a) and (b) is set to 38-62 mass% {the content ratio of (b) being 62-38 mass%}, and the blending amounts of (c) and (e) relative to 100 pts.mass of the liquid component are set to 5-13 pts.mass and 3-13 pts.mass, respectively.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 present invention relates to a dental disclosing composition and a screening method therefor, and more specifically, to a dental disclosing composition comprising cacao pigment or gardenia blue pigment, and a screening method therefor. Containing a natural material that has stable chemical properties, food-grade usability, and dyeability, the composition is ingestible and suitable as a substitute for conventional disclosing solutions. Moreover, the composition is expected to be widely applicable as a means for evaluating the effectiveness of dental disclosing materials.

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.

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.
