Localization of maxillary third molar immobilized within an infected maxillary sinus.

Because a condition of this type could not be detected with intraoral radiographs, the panoramic radiograph was the logical choice for further diagnostic information without resorting to the specialized extraoral radiographs of the maxillary sinus (Waters' view or anteroposterior extraoral radiograph, for example). As the panoramic radiograph is a fast, simple, and relatively inexpensive procedure, all dentists should make use of this technique when a patient with these symptoms is involved.
