    Abstract: An oral composition and a method of delivering an oral composition to a dental structure are described. The oral composition can include a solvent; an acidic copolymer having acidic acrylate monomeric units, acidic methacrylate monomeric units, or a combination thereof; a neutral copolymer having neutral acrylate monomeric units, neutral methacrylate monomeric units, or a combination thereof; and optionally an active agent. The acidic and neutral copolymers can be dissolved in the oral composition and the oral composition can form a film on a surface when contacted with an aqueous solution.

    Abstract: The invention relates to a dental composition comprising polymerizable components, an initiator suitable for curing the polymerizable components, a Ca-ions releasing component having a Ca-ions releasing capability of 400 to 700 mg/l (ppm) if 2.5 g Ca-ions releasing component is steered in 50 ml de-ionized water having a pH of 2 for 24 hours; a F-ions releasing component having a F-ions releasing capability of 1,500 to 3,500 mg/l (ppm) if 2.5 g F-ions releasing component is steered in 50 ml de-ionized water having a pH of 7 for 24 hours. The invention also relates to a kit of parts comprising such a dental composition according and the following items alone or in combination: dental adhesive, dental milling block, prefabricated dental crown. The dental composition is suitable for use in a process of remineralizing a defect tooth in the mouth of a mammal, the process comprising the step of fixing a dental restoration to the surface of the defect tooth with the dental composition.
