摘要： Provided is an oral composition containing particles that have properties to seal dentinal tubules and excellent adhesion properties in dentinal tubules. Specifically, provided is an oral composition containing hydroxyapatite particles, wherein the hydroxyapatite particles have a ratio of a diffraction peak intensity around 2θ=32° to a diffraction peak intensity around 2θ=26° of 0.8 to 1.6 in an x-ray powder diffraction pattern as measured with CuKα characteristic X-rays.
