Pathophysiological mechanisms of persistent orofacial pain

Central mechanisms of orofacial pain.

The orofacial pain clinician must understand the difference between peripheral and central mechanisms of pain. Particularly, one has to understand the process of central sensitization as it relates to the various orofacial pain conditions to understand orofacial pain. Understanding leads to more effective treatment.

Assessment of the Psychological Comorbidity, Pathophysiological Mechanisms, and Treatment Implications in Patients with Chronic Orofacial Pain

Chronic orofacial pain is a multifaceted health problem that like many other forms ofchronic pain bears deleterious effects upon quality of life as well as psychological andphysiological well-being. Due to a poorly understood etiology, effective treatment strategies are lacking and tend to lack a guiding integrative conceptual framework toform the basis and development of intervention. This rev...

Neuropathic pain: diagnosis, pathophysiological mechanisms, and treatment.

Neuropathic pain develops as a result of lesions or disease affecting the somatosensory nervous system either in the periphery or centrally. Examples of neuropathic pain include painful polyneuropathy, postherpetic neuralgia, trigeminal neuralgia, and post-stroke pain. Clinically, neuropathic pain is characterised by spontaneous ongoing or shooting pain and evoked amplified pain responses after...

Transition to persistent orofacial pain after nerve injury involves supraspinal serotonin mechanisms.

The orofacial region is a major focus of chronic neuropathic pain conditions characterized by primary hyperalgesia at the site of injury and secondary hyperalgesia outside the injured zone. We have used a rat model of injury to the maxillary branch (V2) of the trigeminal nerve to produce constant and long-lasting primary hyperalgesia in the V2 territory and secondary hyperalgesia in territories...
