RADIOGRAPHIC EXPOSURE TECHNIQUES

TYPES OF INTRAORAL RADIOGRAPHIC FILM AND THEIR PURPOSES

a. Periapical. The periapical film provides information concerning the entire tooth and adjacent tissues.

b. Bite-wing (Interproximal). The bite-wing film aids in the detection and determination of depth of caries or other defects of the coronal two-thirds (the crown portion) of opposing teeth and the surrounding alveolar crest.

c. Occlusal. The occlusal film provides a means of examining larger areas of the jaws and does so from a different angle than is possible with other intraoral methods. It is valuable in locating and diagnosing fractures, salivary duct stones, and impacted teeth. Occlusal radiographs are used much less than periapical and interproximal radiographs.
