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