Can infrared thermography be a diagnostic tool for arthralgia of the temporomandibular joint?

This paper presents a review of the use of infrared thermography in diagnosis of temporomandibular joint (TMJ) arthralgia. The question examined was whether the infrared thermography could be reliably used as a tool to diagnose arthralgia by objectively assessing the site of origin and the degree of irritation. Controlled studies were performed by using advanced thermographic devices to show both diagnostic validity and reliability of infrared thermography as a screening test for selecting healthy subjects from patients with unilateral TMJ arthralgia.
