A dental article includes a shell defining a volume, the shell including a circumferential base and an incisal/occlusal region distal from the circumferential base. A hardenable dental composition is located within the volume of the shell, and an isolation film is located at the circumferential base of the shell.

A borate bioactive glass is described, and may be used in the form of particles in an acidic mixture to form a borate bioactive glass paste. The borate bioactive glass paste may be used for the restoration of dentin and enamel on a tooth surface by the precipitation of calcium phosphate. The borate bioactive glass may also be used as a bone grafting material.

Endodontic instruments are described which have at least a section with a center of mass offset from an axis of rotation so that when the instrument is rotated, the section bends away from the axis of rotation.

The invention relates to a method for contructing at least one dental prosthetic part (20) or a bracket, with at least one adhesive surface (2), in which a 3D model (1) is made of the dental prosthetic part (20). Recesses (3,9,12,15,29,31) are constructed on the adhesive surface (2) of the 3D model (1).

Radically polymerizable dental material which contains (a) at least one polyfunctional radically polymerizable monomer, (b) at least one further radically polymerizable monomer which can be monofunctional or polyfunctional, (c) at least one photoinitiator for the radical polymerization and (d) at least one filler. The material is characterized in that the mixture of the monomers (a) and (b) has a refractive index of from 1.50 to 1.70 and in that the refractive index of the monomer mixture before the curing corresponds to the refractive index of the filler used or is higher by up to 0.013 and after the curing is higher than the refractive index of the filler by at least 0.02.
