PHOTOGRAPHING METHOD TO TOOTH ADJACENT SURFACE, AND OCT DEVICE FOR PHOTOGRAPHING TOOTH ADJACENT SURFACE

摘要

PPROBLEM TO BE SOLVED: To provide an OCT device for photographing tooth adjacent surfaces, enabling right examination of dental decay on tooth adjacent surfaces. PSOLUTION: The device includes a light source 110, an OCT probe 140 including a sheath 150 and a probe body 131, a light guide means, and an image display part 125. The probe body 131 injects light to the tooth adjacent surface as an observation object 200, and sweeps reflection light to the light guide means to display an image based on the reflection light on the image display part 125. The OCT probe 140 includes a rotation means 160 to drive rotation of the probe body 131, and a moving means 171 to move the probe body 131 forward and back in the sheath 150. The OCT probe 140 is inserted to a drum-shaped hollow between teeth to be at least either rotated or moved forward and back to photograph the tooth adjacent surfaces. PCOPYRIGHT: (C)2011,JPO&INPIT
