摘要

PROBLEM TO BE SOLVED: To provide a method for obtaining the images in a wide range from a root sharp part to an occlusion part and a photographing tool for obtaining the images excellent in reproducibility in the X-ray photographing of teeth using the CCD sensor of an insufficient height dimension. SOLUTION: This X-ray photographing tool for which a light receiving body mounting plate 6 is provided on one end part of a planar fixing base plate 1 at the angle of 20-45 degrees, 25-35 degrees preferably, to the vertical line of the fixing base plate l and an X-ray tube guide panel 9 is made to face the light receiving body mounting plate 6 at the other end part of the fixing base plate 1 is used. The CCD sensor is mounted to the light receiving body mounting plate 6 and the images for which the dimension in a vertical direction of the tooth is compressed to 70-90% are photographed.
