Abstract
The invention relates to intraoral radiological dental image sensors, i.e. sensors placed in the mouth of a patient, an X-ray source being located outside the cheek of the patient in order to emit X-rays in the direction of the sensor. According to the invention, the image sensor is attached to a first end of a short electrical cable () of around 5 to 20 cm, a second end of which leaves the patient's mouth when the sensor is in the mouth, the second end carrying a light source () comprising light-emitting diodes that can be digitally modulated as a function of information coming from the sensor, the electrical cable being able to transmit an electrical control signal from the sensor to the diode for modulating the latter.
