Pain involving the facial and oral regions which may be of dental or non-dental origin. Pain from the dento-alveolar complex may be pulpal, dentinal, or periodontal in origin or may also arise from thermal sensitivity, cracked tooth syndrome, or maxillary sinusitis. Orofacial pain may arise from the musculo-ligamentous or soft tissues such as idiopathic orofacial pain, temperomandibular dysfunction, salivary gland disease, oral lesions, candidiasis, or malignancy. Orofacial pain of neurological or vascular origin may be associated with burning mouth syndrome, trigeminal neuralgia, cluster headache, post-herpetic neuralgia, cranial arteritis, or glossopharyngeal neuralgia. See also facial pain.
