ABSTRACT:
A dental panoramic X-ray photographing apparatus including a rotary arm having an X-ray generator disposed at one end thereof and having an X-ray film cassette holder disposed at the other end thereof in an opposite relation with each other around an object disposed therebetween. The apparatus comprises a first control means for controlling the rotation speed of the arm by detecting the rotation position of the arm and a second control means for controlling the tube voltage and the tube current of the X-ray generator by comparing the feeding speed of the X-ray film at the X-ray film cassette holder with the residual X-ray dose which has passed the object and the film, whereby it is intended to provide the simultaneous control function of the tube voltage and the tube current, the function for automatic exposure throughout the entire teeth and the function for compensating for the density of the central portion of the front tooth region of a dental arch at the same time.
