A dental diagnostic OCT system capable of diagnosis of dental caries existing at the approximal surfaces of teeth, comprising a light source (10), a beam splitter (20), a mirror (62), a photo detector (40), a lens (51), an optical fiber (52), and a probe (60). A filler having a refractive index larger than the refractive index of air and smaller than that of an object of diagnosis is to be filled between the tip portion of the probe and approximal surfaces of teeth, i.e., objects of diagnosis. The light output from the tip portion of the probe is irradiated to the objects of diagnosis via the filler, and the sample light occurring upon such irradiation is input into the tip portion of the probe via the filler. The intensity of light which the beam splitter outputs by combining the sample light and the reference light is detected by the photo detector, and thereby the teeth as the objects of diagnosis are diagnosed.
