Abstract
The photographing of occluding surface needs that of superior maxilla and palate. It goes without saying the photographing of occluding surface is very important for diagnosis. In spite of this importance, any kasette used for the photographing of occluding surface has not been in use yet. Therefore, the treatment of film in dark-room is inconvenient and the photographing often gives much uncomfor-tableness to patients. But today only little attention is paid to this kasette in the area of dental surgery. This problem is noticed here. and a dark slide is designed, made and put to practical use.
