ANATOMIC RADIOGRAPHIC LANDMARKS

GENERAL

A number of anatomic landmarks are visible in dental radiographs. Knowledge of the location and normal appearances of these landmarks is important in identification and orientation of radiographs. This knowledge is valuable to the dental officer in determining whether the area is normal or abnormal. The landmarks that appear as dark areas on the film are radiolucent. The areas that appear as light areas on the film are radiopaque. Anatomic characteristics and the relationship between individual teeth are anatomic landmarks with which all dental specialists should be familiar.
