The invention relates to a process for the preparation of a citrate-coated amorphous calcium phosphate nanoparticle which comprises the following steps: 1) providing a first solution of a salt of calcium and a citrate salt wherein the molar ratio of citrate ion to calcium ion is in the range from 1 to 2 thus obtaining a clear first solution; 2) providing a second solution of a salt capable to give phosphate anion and a carbonate salt; 3) mixing together the first and the second solution at a pH in the range from 8 to 11; 4) precipitating the nanoparticle; and 5) drying the nanoparticle obtained from step 4). Preferably and advantageously the invention provides for the addition of a fluoride compound in step 2) for obtaining a fluorine-doped citrate-coated calcium phosphate nanoparticle or a nanoparticle agglomerate. The nanoparticle/nanoparticle agglomerate of the invention has a peculiar superficial area and a diameter that allow to use it as a biomaterial for dentistry application.

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.
