Chronic Orofacial Pain

Abstract

Chronic orofacial pain (COFP) is an umbrella term used to describe painful regional syndromes with a chronic, unremitting pattern. This is a convenience term, similar to chronic daily headaches, but is of clinically questionable significance: syndromes that make up COFP require individually tailored diagnostic approaches and treatment. Herein we describe the three main categories of COFP: musculoskeletal, neurovascular, and neuropathic. For many years, COFP and headache have been looked upon as discrete entities. However, we propose the concept that because COFP and headaches share underlying pathophysiological mechanisms, clinical characteristics, and neurovascular anatomy, they should be classified together.

Trigeminal autonomic cephalgias

“…-В 20% случаев головная боль может перемещаться между кластерами или между приступами одного кластера на другую сторону [41].…”

“…-Более 85% пациентов оценивают боль в 8-10 бал-лов по визуально-аналоговой шкале, некоторые характе-ризуют боль как «суицидальную» вследствие чрезвычай-ной ее интенсивности [41].…”

“…Приступ постоянной гемикрании провоцируют раз-личные факторы: наклоны головы, менструация, сильные запахи, стресс, алкоголь [41].…”

Neuropathic pain after dental treatment

“…Still, the incidence of persistent pain is not known. [12,38,49,50] IAN can be damaged due to over instrumentation during root canal treatment of the mandibular molar teeth, pressure in the IAN canal from endodontic point or sealant, and the neurotoxic effect of the medication used in the root canal. [51][52][53][54] After root canal therapy persistent pain was reported in 3-13% of cases [55] whilst endodontic surgery ends with painful phantom tooth in 2% to 3% of cases.…”

“…Typically dentists intend to solve the problem with traditional dental treatments which may cause the patient to lose their teeth found the jaw affected. [12] Pathophysiology of neuropathic pain Several types of sources, such as vascular compression, radiation, inflammation, trauma, infection, and exposure to neurotoxins to the peripheral nervous system can lead to pathologic damage. [3,13] Demyelination and axotomy (deafferentation with severance of the axon) are the ways to incur these damages.…”
