The utilization of contact liquid crystal thermography in the evaluation of temporomandibular dysfunction.
A previously diagnosed patient population of 109 volunteers having temporomandibular dysfunction agreed to undergo pretreatment and post-treatment thermographic examination. In 1988, at the time of this study, a contact liquid crystal thermographic unit was utilized in accordance with the protocol advocated by the Academy of Neuro-Muscular Thermography. The examination consisted of pretreatment and post-treatment thermograms repeated in a series of three sets, i.e., in triplicate, incorporating four different views per set, namely, frontal face, right lateral face, left lateral face, and posterior cervical. This study revealed that the application of contact liquid thermography in the evaluation of temporomandibular dysfunction was a reliable, valid, and efficacious diagnostic tool in approximately 95% of the cases. Resolution of thermographic asymmetry and/or decrease in Delta T was demonstrated in approximately 81% of the post-treatment population. Thermography also proved to be a reliable indicator of pretreatment duration of dysfunction (chronicity pattern) in approximately 78% of the cases.
