Dental compositions and methods provide a flowable ceramic powder of a powdered component, wherein the compositions and methods comprise at least one dental glass, glass ceramics, metal oxide, mixed oxide selected from metal oxides and/or a mixture comprising at least two of said components, a printable dental ink. Moreover, the compositions and methods produce dental prosthetic form bodies.

Lithium silicate glass ceramics and glasses are described which can advantageously be applied to zirconium oxide ceramics in particular by pressing-on in the viscous state and form a solid bond with these.

A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g. sealant) composition for application to a tooth structure.

Provided is a fluoroaluminosilicate glass powder that can provide a dental glass ionomer cement hardened body excellent in acid resistance, the glass powder including sodium and potassium which have an effect of lowering the reflective index of glass. A mass ratio of potassium to sodium in the component is in the range of from 1.2 to 1.9 in terms of oxide.

Glass ceramics having SiO.sub.2 as main crystal phase and precursors thereof are described which are characterized by very good mechanical and optical properties and in particular can be used as restoration material in dentistry.
