[The contribution of standard radiographs in the evaluation of masticatory system dysfunction].
Conventional x-ray films (orthopantomogram, teleradiogram) visualize many signs of dysfunction of the manducatory apparatus (DAM). Progress in our knowledge of the pathophysiology of DAM has brought new light to these radiographic signs. The orthopantomogram allows an assessment of modifications in muscle insertion zones secondary to their dysfunction and, more difficulty, the articular remodeling of the TMJ, mainly of the mandibular condyle and the articular space. The lateral teleradiogram studied by architectural and structural analysis provides information on the biomechanical balance of the cranio-facial structures and, especially, on the position of the mandibular rami. These standard radiograms are indispensable in the differential diagnosis, useful in the etiological diagnosis and are preliminary examinations prior to using other imaging techniques (MRI, CT). Standard films are easily reproducible for post-therapy follow-up.
