5.3 Patient position
Keep the patient in the correct sitting position, place film or digital imaging sensor, with the protection. Then adjust the angle and position between the X-ray generator and the patient.

The film or digital sensor placed in the mouth or on a film holder, and the film or sensor should be parallel to the long axis of the tooth.

Ask the patient to hold the film or digital sensor with their fingers on the exposure position in the mouth. Position the X-ray perpendicular to an imaginary line that bisects the angle between the film or digital sensor plane and the long axis of the tooth perpendicularly.

X-ray inclination average angle when shooting upper and lower teeth
