Abstract: Proposed are a method of preparing new biomaterials for dental pulp regeneration and a composition of new biomaterials prepared accordingly. The composition of new biomaterials prepared according to the method of preparing new biomaterials for dental pulp regeneration by mixing a first precursor containing calcium silicate-based cement (CSC) at an appropriate concentration and a second precursor containing a secretome of dental pulp-derived mesenchymal stem cells in an appropriate ratio and then drying the resulting mixture under appropriate drying conditions is characterized by further improving the osteogenic differentiation ability of dental pulp stem cells compared to existing materials while maintaining the microhardness of the composition to an appropriate standard. In addition, the composition is advantageous in that an aesthetic effect is excellent by not causing tooth discoloration.

Abstract: A laminate film comprising a retardation layer exhibiting blocking characteristics against specific ultraviolet rays even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The laminate film which can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The laminate film can also be formed with a lower thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the laminate film exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.
