PROBLEM TO BE SOLVED: To provide a dental oral cavity radiographic device and the like which can obtain an X-ray image of a radiography target tooth easily and accurately.SOLUTION: The dental oral cavity radiographic device includes: an imaging part 10 including an imaging member having any one of an imaging plate, an X-ray film, and an X-ray imaging element; an X-ray irradiation part 70; and an imaging auxiliary tool 50 including a retention part retaining the imaging part in a rotatable state and a guide part connected with the retention part, arranged at a position facing the imaging member, and used for positioning of the X-ray irradiation part 70. The imaging auxiliary tool 50 or the imaging part 10 includes an angle sensor acquiring information on an angle formed by the imaging part 10 and the retention part. The guide part includes an actuator 65 retaining the X-ray irradiation part 70 and moving the X-ray irradiation part 70. Movement control of the X-ray irradiation part by the actuator 65 is performed based on the information on the angle acquired by the angle sensor.SELECTED DRAWING: Figure 3 |
