摘要:
A dental adhesive composition comprising: (A) 100 parts by weight of a polymerizable unsaturated monomer containing 5% by weight or more of a radical polymerizable monomer having an acid group; (B) 35 to 100 parts by weight of an acid-reactive filler; (C) 35 to 100 parts by weight of water; (D) 5 to 100 parts by weight of a water-soluble organic solvent; and, (E) 0.1 to 10 parts by weight of a polymerization catalyst.
摘要:
The present invention provides a primer composition comprising (i) 0.5-90% by weight of water, (ii) 5-90% by weight of a polymerizable compound having hydroxyl group, (iii) 0.1-90% by weight of a polymerizable compound having acidic group, and (iv) 0.01-30% by weight of a curing agent. When dental adhesive restorative materials such as dental resin cements, composite resins, PMMA resins and the like are made to adhere directly or through bonding agents to substrates such as vital hard tissues, especially an enamel or a dentin of natural teeth, glass ionomer cements and the like, the primer composition is able to impart a strong and durable adhesive property between the both without treating said substrates with an acid and the like.
摘要:
A tooth surface treating agent is provided which comprises a polymerization catalyst and an acidic compound, both water-soluble, the treating agent being capable of enhancing tooth adhesion. The tooth surface treating agent imparts strong adhesion to the enamel and dentin of teeth through simultaneous treatment thereof. The invention is mainly intended for use in the field of dentistry, but is also applicable as a treating agent for vital hard tissues in such fields as surgery, and orthopaedic or plastic surgery.

摘要:
The present invention provides a one-liquid curable composition comprising micro- and/or nano-capsules. More specifically, the present invention provides a one-liquid curable composition characterized in that a substance encapsulated within each micro- and/or nano-capsule and a substance enveloping said micro- and/or nano-capsule contain a combination of more than one material that can coexist with one another, selected arbitrary from radically-polymerizable monomers, polymerization initiators, polymerization accelerators, electrolyte polymers, electrolyte polymer solutions, hydroxycarboxylic acids, hydroxycarboxylic acid solutions, acid-reactive fillers, and acid-inactive fillers, and also characterized in that a wall material of said micro- and/or nano-capsule is an organic compound, and/or an inorganic compound, and/or an organic/inorganic complex compound.
摘要:
There is provided a fluoride-ion sustained release pre-formed glass ionomer filler comprising a powdery reaction product of polyalkenoic acid with a fluorine-containing glass, and a method of producing the same. There is also provided a dental composition containing the filler. The fluoride-ion sustained release pre-formed glass ionomer filler is long capable of releasing fluoride ions in the presence of water without involving disintegration. The dental composition of the invention is useful particularly for prevention of dental caries and like trouble.
