Positioning the Radiograph

Positioning the radiograph vertically in the mouth for both periapical and bitewing radiographs reduces the distal extension of the radiograph and may result in greater tolerance by patients, especially those with a mild gag reflex. The vertical bitewing radiograph provides greater detail of the periapical area. A self-sticking sponge tab may also reduce impingement of the radiograph on the intraoral soft tissue.
