This invention concerns a dental pin made of composite material, including a core made up of fibres embedded in a resin matrix. The pin is characterized by the fact that the fibres that have a refraction index (n) are radio-opaques, and that the refraction index (n') of the resin constituting the matrix has a value close to that (n) of the fibres.
