摘要: A dental curable composition that allows easily identifying the presence of in an oral cavity is provided. visible-light contains a fluorescent substance generates fluorescence when irradiated with visible light. The compound formula A3B2C3O12 containing Ce, absorbs light peak wavelength range 380 to 500 nm, and 550 780 nm. In A3B2C3O12, A, B, C are dodecahedral eight-coordinate Y element, octahedral six-coordinate Al tetrahedral four-coordinate respectively.
