An inorganic-organic composite medical material includes a two-phase co-continuous structure of an inorganic substance having open pores and an organic polymer filling the open pores, wherein the open pores have an average pore diameter of 1 nm or more and 100 nm or less, and the inorganic substance has a specific surface area of 100 m/g or less.

Inorganic-organic composite medical material and method for producing inorganic-organic composite medical material

The present invention provides a dental material, a dental material composition and a dental restorative material that exhibit small polymerization shrinkage particularly during curing and are producible at low cost on the industrial scale. The dental material of the present invention includes a specific urethane (meth)acrylic compound represented by Formula (1) described below. 

Dental material, dental material composition, dental restorative material, and cured product

The present invention provides a novel compound and a composition including the compound that exhibit small polymerization shrinkage particularly during curing and are producible at low cost on the industrial scale. The compound of the present invention is represented by Formula (1): 

Compound, composition comprising the compound and cured product

A kit for dental adhesive comprising a radical polymerizable monomer having an acid group in the molecule, a photosensitizer and/or a peroxide, a water-soluble organic solvent, an organic sulfinic acid and/or a salt thereof or a barbituric acid and/or a derivative thereof, and water. The kit may further comprises a radical polymerizable monomer which has no acid group and is insoluble or hardly soluble in water, an amine compound, a silane coupling agent and a 1,3,5-triazine-2,4-dithion derivative. By using this kit, the adhesive composition can be applied directly to a dentine without conducting a pretreatment.
