In this study, Y2O3:RE was prepared and applied for the composite resin (CR). Y2O3:RE contained CR was well cured with NIR irradiation and its Vickers hardness was higher than the CR with commercial spherical silica fillers. Also, Y2O3:RE contained dental fisher sealant showed good hardness and high visibility under UV irradiation. Thus, the feasibility of Y2O3:RE as the filler of dental CR and sealant was suggested.2010jpnengbook partVoRhttp://hdl.handle.net/2115/44532傾斜機能材料論文集vol24, p.76-81(ISBN978-4-9901902-6-2)https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/44532/1/FGM2010_UCFiller_HUSCAP.pdfapplication/pdf2.28 MB2010
