Background: Different therapeutic approaches have been proposed for the treatment of TMD. Myofascial and joint techniques, exercises, intraoral devices, thermal, electro and phototherapy applications, are among the most common. The combination of local treatments and adjacent structures such as the cervical region have also been studied in this area. It is believed that the anatomic proximity, neuronal interconnections and convergent afferents from the trigeminal and cervical areas can lead the understanding of the relationship of these structures. In order to assess the effects of these different forms of treatment studies have used different resources such as diagnostic imaging and biological signals, in order to complement the clinical diagnosis. Infrared thermography has been one of the resource assessment in the literature and it is interesting and stands out from other methods because it is functional, non-invasive and inexpensive.
