Temporomandibular Joint Disorders and Their Radiographic Diagnostic Criteria - L0775


About Course #L0775

Release Date: August 17, 2016

Expiration Date: December 31, 2019

Temporomandibular joint (TMJ) disorder is an umbrella term used to describe conditions with differing etiologies that cause pain and dysfunction of the TMJ and structures related to mastication. Pain is the most important symptom in TMJ dysfunction for both the patient and the clinician, and is the main reason why patients with TMJ disorders (TMJD) seek medical help. The multifactorial TMJD etiology may be related to trauma, masticatory muscular dysfunction, postural deviation, internal and external changes in TMJ structure, and the various associations of these factors.

This intermediate-level course provides dentists, hygienists, and assistants with a review of TMJ disorders, their etiologies, and proper imaging techniques for accurate diagnoses of these disorders. The course overviews the most common TMJ-related disorders and the most appropriate imaging techniques for each. The latest recommendation that imaging should be based on the clinical needs of the patient and not obtained routinely is discussed.
