Orofacial pain disorders Orofacial pain is a frequent form of pain perceived in the face and/or oral cavity. It may be caused by diseases or disorders of regional structures, dysfunction of the nervous system, or through referral from distant sources (IASP 2013) Prevalence up to 22% of the general population. On an average, A patient with orofacial pain condition has been evaluated by three clinicians prior to arriving at an accurate clinical management of the condition. (c) 2016 Subha Giri BDS MS 3

Clinical evaluation of Orofacial pain Vital signs and cranial nerve evaluation Vision and Ear evaluation and exclusion of infectious or inflammatory disease. Cervical evaluation with range-of-motion and pain referral. Palpation of the muscles of mastication and temporomandibular joints. Range of motion of the temporomandibular joints. (c) 2016 Subha Giri BDS MS 6

Clinical Evaluation Range of Mandibular Movement a. Average mandibular range of motion inter incisally is at least 40 mm. b. open slowly until pain is first felt ; open slowly to the maximum. c. Mandibular deviation and deflection. (c) 2016 Subha Giri BDS MS 8
Clinical Evaluation TMJ evaluation a. Palpation of the lateral aspect of the joints simultaneously. b. Palpating the lateral poles of condyles with medially directed force. c.

Absence of local infectious or inflammatory disease upon clinical evaluation (c) 2016 Subha Giri BDS MS 14
Neurovascular Orofacial Pain disorders Concurrent presentation of headache not sufficiently treated with gold standard headache management. Headache duplicated with the palpation of orofacial structures particularly the TMJs and Muscles of mastication Abnormal Lab with elevated sed rate for Arteritis. (c) 2016 Subha Giri BDS MS 15
