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

An object of the present disclosure is to provide a dental composition that can exhibit sufficient curability even in a state where moisture is excessive as in the oral environment. The dental composition of the present disclosure contains component (a): monomer containing (meth)acrylamide group represented by formula (1): (In formula, R represents a hydrogen atom or a methyl group and Rs may be the same or different from each other. R2 is an alkyl group having 2 to 6 carbon atoms and R2s may be the same or different from each other.)

Low water-sensitive dental composition

The present invention relates to a polymerization catalyst having storage stability under an oral cavity environment. Furthermore, the present invention relates to a dental material cured by use of the present polymerization catalyst. The polymerization catalyst for use in the dental material is achieved with including 1-cyclohexyl-5-propylbarbituric acid and trioctylmethylammonium chloride.

Dental material including propylbarbituric acid polymerization catalyst

The present invention relates to a dental curing composition to restore a lost portion of a tooth generated due to dental caries, tooth fracturing, etc. The dental curing composition has packability suitable for restoring a posterior tooth; has a paste character of avoiding stickiness to a filling instrument; has excellent shaping properties; has very little paste character over time; and has a low polymerization shrinkage property. The dental curing composition comprises: (a) a matrix resin whose viscosity at 25&#xb0; C. is 10,000 to 17,000 mPa&#xb7;s, (b) an organic-inorganic composite filler, (c) an inorganic filler, and (d) a polymeric initiator.

Dental curing composition

A dental resin temporary sealing material composition that is excellent in adhesion to the tooth substance and removability of the hardened material and has a preventive function of releasing various ions including a fluoride ion is provided. The adhesion to cavity walls can be improved and, since there is little dimensional change during hardening, excellent sealability in a cavity can be attained.
