Patient Preparation

Regardless of technique, the patient must be prepared prior to the procedure. The first step is to explain the general aspects of the procedure to the patient. Additional pre-exposure instructions are necessary to avoid the production of unwanted artifacts and ensure patient cooperation. For intraoral radiography, the patient must be instructed to remove facial jewelry in the beam path (for instance, nose rings or large earrings), eyeglasses and intraoral prostheses. In addition with panoramic radiography, all metallic objects from the head and neck region must be removed including those items described above (Figures 10 & 11). Examples include tongue rings, necklaces, napkin chains, barrettes, hairpins, intraoral prostheses and hearing aids must be removed. The clinician should take care to safely store these items and return them to the patient when the procedure is complete.
