Upon completion of this course, participants should be able to do the following:

1. Recognize the common pericoronal radiolucencies encountered around the crowns of impacted third molars and cuspids.
2. Identify the most common interradicular radiolucency adjacent to vital teeth.
3. Differentiate between lesions characterized by multilocular radiolucencies of varying sizes and shapes.
4. Identify the various radiopacities associated with teeth and the surrounding tissues.
5. Recognize lesions that manifest ground glass opacification characteristics.

Many diseases of the maxillofacial complex are localized, whereas others are manifestations of systemic or multisystem diseases. Regardless of their pathogenesis, diseases that affect teeth, bones, oral mucosa and salivary tissues result in clinically observable tissue changes that subsume many processes. Some diseases that arise central in the jaws are, in fact, odontogenic, while others do not involve the odontogenic tissues. Rather, they affect the osseous and marrow elements, much the same as diseases that arise in other areas of the skeleton. Some jaw lesions are symptomatic, some merely cause expansion or enlargement of the maxillofacial bones and yet others are detectable only on radiographs or other imaging systems. Because radiographs are routinely taken for dental diagnostics, most central jaw lesions are identifiable on the basis of radiography. Central jaw and sinus lesions are, therefore, classifiable according to radiographic features.
