摘要： The present application discloses a fast-setting mineral trioxide aggregate (MTA) with fluoride release for practical treatment of diseases in teeth and bone, e.g. for caries treatment and/or prevention. The cariostatic MTA contain calcia-silica-alumina cement with moderately increased tricalcium aluminate content allowing high calcium hydroxide release. The MTA composition support remineralization and biomineralization, and it is suitable for stimulation of hard tissue regeneration. MTA embodiments contain superplasticizer and nanosilicate for improved mechanical properties. The MTA compositions include optional radiocontrast and nano-enriched leachable fluorine, nitrate, strontium, and phosphate. The fast-setting MTA paste exhibits flow-to-clay-like consistency, which allows new practical applications including cavity lining, temporary restoration, bonding, and cementations in one MTA embodiment. The high calcium hydroxide and high fluoride release are suitable for caries prevention and treatment, and per se inhibition of dental symptoms.

摘要： The present invention provides a one-part dental adhesive that exhibits excellent adhesive properties to both enamel and dentin and that has high storage stability and ambient-light stability. The present invention is a one-part dental adhesive including 1 to 30 weight% of a phosphoric acid group-containing monofunctional (meth)acrylate compound (a), 10 to 50 weight% of a water-soluble polymerizable monomer (b), 5 to 50 weight% of a hydrophobic crosslinkable (meth)acrylate compound (c), water (d), and a polymerization initiator (e). The water-soluble polymerizable monomer (b) includes a combination of a monofunctional (meth)acrylamide compound (b-1) having a particular structure and a water-soluble crosslinkable (meth)acrylic monomer (b-2). The weight ratio between the monofunctional (meth)acrylamide compound (b-1) and the water-soluble crosslinkable (meth)acrylic monomer (b-2) is 10 : 1 to 1 : 5.

摘要： A dental composite having high filler loading and low shrinkage thereby providing good strength and marginal integrity. Through the use of prepolymerized filler particles in combination with a structural filler and a nanofiller, the composite exhibits very low shrinkage and is useful in stress bearing restorations and in cosmetic restorations. The structural filler used is ground to a mean particle size of less than 0.5 mu m and the nanofiller has discrete particles of a mean particle size less than 100 nm to improve handling and mechanical characteristics. The prepolymerized filler particles also allow for less viscosity and better handling characteristics of the composite.

摘要： The present invention discloses an organic-inorganic composite filler that contains: inorganic aggregate particles formed by aggregation of inorganic primary particles with an average particle diameter of 10 to 1000 nm; an organic resin phase including a cured polymer of a polymerizable monomer covering surfaces of the inorganic primary particles and bonding the inorganic primary particles to each other, and a water absorbing resin; and aggregation gaps with a volume of micropores formed between parts of the organic resin phase of 0.01 to 0.30 cm 3 /g in pore volume measurement within a pore diameter range of 1 to 500 nm, as measured by a mercury intrusion technique. In a cross section passing through the centers of the inorganic aggregate particles, based on 100 measured inorganic particles, there are 10 or less inorganic aggregate particles having a macro void with a maximum width of at least 1 µm. The present invention also discloses a method for producing the organic-inorganic composite filler.
