To provide a dental composition wherein the acid buffering capacity can be attained and the acid resistance of the tooth substance can be improved while maintaining very high foul breath inhibition capacity. A dental composition including: ion sustained-release glass; and a carrier for supporting the ion sustained-release glass, wherein the ion sustained-release glass is fluoroaluminoborosilicate glass having a composition range of: 15% to 35% by mass SiO; 15% to 30% by mass AlO; 5% to 20% by mass BO; 20% to 45% by mass SrO; 5% to 15% by mass F; and 0% to 10% by mass NaO.

Dental composition containing ion sustained-release glass

A dental conditioning composition that enhances the adhesiveness of any dental material for a tooth surface by suppressing any excessive demineralization for the tooth surface and improving the polymerization activity of a dental adhesive composition by causing a polymerization catalyst included in the dental conditioning composition of the present invention to remain on the tooth surface. A dental conditioning composition having a gel character, that includes a polymerization catalyst, an acidic compound, water, and a thickening agent, and whose pH (the hydrogen ion exponent) is in a range from 0.1 to 0.9.

Dental conditioning composition

A dental curable composition that allows easily identifying the presence of the dental curable composition in an oral cavity is provided. A dental visible-light curable composition contains a fluorescent substance that generates fluorescence when irradiated with visible light. The fluorescent substance is a compound of formula ABCOcontaining Ce, absorbs visible light with a peak wavelength in a wavelength range of 380 to 500 nm, and generates fluorescence with a peak wavelength in a wavelength range of 550 to 780 nm. In formula ABCO, A, B, and C are a dodecahedral eight-coordinate Y element, an octahedral six-coordinate Al element, and a tetrahedral four-coordinate Al element, respectively.

Dental visible-light curable composition and method of identifying presence of same

The present invention relates to a dental adhesive primer composition for use in dental fields employed to bond dental materials, such as restoration materials, dental crown materials, prosthetic materials, esthetic materials, orthodontic materials, preventive materials, core build-up materials and root canal materials, to ceramics, metals, resins, composite resins, glass ionomer cements, and hard biotissues (enamel or dentin of natural tooth). The present invention also relates to a dental adhesive primer composition including a dental adhesive composition which can be used not only in combination with another adhesive composition but also alone.

Dental adhesive primer composition

The present invention provides a dental curable material suitable for a production of an artificial teeth having a strong toughness, wear resistance, transparency and moldability, which comprises a silane-treated silica uniformely dispersed in urethane (meth)acrylate (a): said silica has a 1 to 85 nm, with at least one silane compound represented by the formula (1):
