The invention relates to a dental X-ray device that includes an X-ray sensor (12) having a sensitive surface (22) capable of detecting the X-rays of an X-ray beam, the sensitive surface (22) being oriented towards a front surface (16) of the sensor, and a sensor positioning device including a receiver (32) for receiving the X-ray sensor (12) and an oblong arm (34) having an end (35) attached to the receiver (32), and a protruding portion (34B) located at the front of the sensor (12), which protrudes outside the mouth of a patient. The receiver (32) is contained in a cylindrical rear space (33B) extending at the rear of a rear surface (18) of the sensor (12) opposite the front surface (16), the cylindrical rear space (33b) being defined by the movement, along a side edge of the sensor (12), of a generatrix straight line perpendicular to the sensitive surface (22). |
