A simple device for positioning intraoral x-ray sensors.

This article describes a simple technique for positioning an intraoral x-ray sensor in patients who are undergoing procedures such as endodontic treatment or post fitting for a crown. By placing a wooden tongue depressor and sensor inside an infection control barrier, the patient is able to hold the sensor comfortably in position without removing the rubber dam clamp, while the patient's fingers are kept out of the path of the x-ray beam.
