[Distinguishing temporomandibular pain from other types of orofacial pain based on a questionnaire].

This study investigated whether, apart from the usual tools for the diagnosis of temporomandibular pain, a questionnaire can distinguish between temporomandibular pain and other types of orofacial pain, based on the biopsychosocial model. 509 patients, who reported orofacial pain in an online questionnaire, were divided into 2 groups based on a clinical examination: patients with temporomandibular pain and patients with orofacial pain in whom temporomandibular pain was excluded. Logistic regression analyses showed that the 2 patient groups did not differ from each other with regard to the majority of biological and psychological aspects of the biopsychosocial model. However, patients with temporomandibular pain reported bruxism and non-specific pain more often, and reported a higher intensity of pain. This study showed that a questionnaire can aid in distinguishing patients with temporomandibular pain from patients with other types of orofacial pain.
