摘要： A radiation device comprises: a housing comprising: a base portion; a head portion connected to the base portion; a radiation emission window in the head portion; a radiation source arranged in the region of the base portion in the interior of the housing for emitting electromagnetic radiation, the radiation source having an emission intensity maximum at a wavelength in the range from 350 to 600 nm; and a mirror arranged in the region of the head portion in the interior of the housing. A radiation path extends between the radiation source and the mirror. Electromagnetic radiation emitted by the radiation source arrives at the mirror via the radiation path. The electromagnetic radiation arriving at the mirror via the radiation path is reflected by the mirror, such that the reflected electromagnetic radiation exits the housing through the radiation emission window.

摘要： Disclosed herein are methods for creating opalescence in dental materials and restorations, compositions used in such methods, and the resultant dental materials and restorations. More particularly, the opalescence may be created by directly embedding opalescent particles into a matrix material. In some embodiments, photonic crystals are embedded in the dental material to achieve the opalescent effect. Photonic crystal particles may be embedded in dental materials matrices such as ceramics, composites, and polymers, and can generate opalescence in the materials. Some embodiments disclose compositions for applying the opalescence to a dental restoration.

摘要： The present invention provides a method that enables production of a surface-treated colored inorganic particle with which the desired color tone can be consistently reproduced as intended with no variation occurring in the color tone of the compositions produced with the particle, within each production and over multiple production runs. The invention relates to a method for producing a surface-treated colored inorganic particle, comprising spray drying a mixture of a dispersion [I] and a solution [II], wherein the dispersion [I] is a dispersion of inorganic particles having an average particle diameter of 0.005 to 5 μm dispersed in a solvent with a pigment, and the solution [II] is a solution of a surface treatment agent hydrolyzed in the presence of a hydrolysis aid.
