Since the temporomandibular joints are components of the stomatognathic system that dentist is most familiar with problems relating to this joints must be recognized, understood and treated by dentists. A comprehensive evaluation of this joint problems must include the radiographic examination. Transcranio lateral is the most commonly used of all conventional TMJ radiographic projection from the lateral aspect that shows the condyle, fossa and eminence as well as the condylar fossa relationship in selected functional movements, but which is not free from superimposed of the adjacent structures. A modified positioning device has been developed over this past years to overcome these superinposition problems. The use of "Condy ray" and "Accurad 200" apparatus that have some advantages over the standard transcraniolateral radiographic projection will be discussed in this paper.
