When there is a clinical absence of a number of teeth and the history indicates that they have not been extracted, partial anodontia and tooth impaction can be considered. Radiographic examination, however, may reveal multiple impacted teeth and partial anodontia can be rejected.1-3 Panoramic radiographs may show multiple impacted teeth or in some instances radiopacities scattered throughout the jaws. Periapical films enable the clinician to readily identify the radiopacities as impacted teeth.1 Details of the number and shape of the tooth roots, external resorption and initial stage cystic changes associated with the impacted teeth can be better visualized on periapical radiographs. Occlusal radiographs may be helpful in identifying the location and number of impacted teeth.
