  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 A3B2C3O12 containing 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 A3B2C3O12, 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.

  本发明提供了一种牙科可固化组合物，可轻松识别口腔中是否存在该牙科可固化组合物。牙科可见光固化组合物含有一种荧光物质，当可见光照射时会产生荧光。该荧光物质是一种含 Ce 的式 A3B2C3O12 化合物，可吸收峰值波长在 380 至 500 纳米范围内的可见光，并产生峰值波长在 550 至 780 纳米范围内的荧光。在式 A3B2C3O12 中，A、B 和 C 分别是十二面体八配位 Y 元素、八面体六配位 Al 元素和四面体四配位 Al 元素。

  A single-paste, self-adhesive dental curable composition that has strong self-adhesion to biological hard tissues (such as enamel and dentin of teeth) and good color tone adaptability suitable for use for aesthetic restoration is provided. A dental curable composition contains: an inorganic particle (A) with an average grain size in the range of 0.1 to 50 µm; an inorganic particle (B) with an average grain size in the range of 0.1 to 50 µm; a polymerizable monomer (C); and a polymerization catalyst (D). The refractive index na of the inorganic particle (A) and the refractive index nb of the inorganic particle (B) meet the relationship of na > nb. A cured resin material (E), which is obtained by curing a polymerizable composition containing the polymerizable monomer (C) and the polymerization catalyst (D), has a refractive index ne that meets the relationship (1): 0≤na-ne<0.01≤ne-nb≤0.05

  本发明提供了一种对生物硬组织（如牙齿的珐琅质和牙本质）具有很强的自粘性和良好的色调适应性，适合用于美学修复的单贴自粘牙科固化组合物。牙科固化组合物包含：平均粒径在 0.1 至 50 微米范围内的无机颗粒（A）；平均粒径在 0.1 至 50 微米范围内的无机颗粒（B）；可聚合单体（C）；以及聚合催化剂（D）。无机颗粒（A）的折射率 na 和无机颗粒（B）的折射率 nb 符合 na > nb 的关系。通过固化含有可聚合单体（C）和聚合催化剂（D）的可聚合组合物得到的固化树脂材料（E）的折射率 ne 符合关系式（1）：0≤na-ne<0.01≤ne-nb≤0.05
