Fibromyalgia (FM) is a syndrome characterized by chronic widespread pain, stiffness, nonrestorative sleep, fatigue, and comorbid conditions. Fibromyalgia has undergone a major paradigm shift in recent years. It is no longer considered a musculoskeletal disorder per se; rather, it represents one end of a spectrum of disorders characterized by chronic widespread pain. Hence, oral health care providers may be the first to recognize signs and symptoms of this complex disorder and are often consulted to participate in the management of FM patients. This medical management update will review the epidemiology, classification, etiology and pathophysiology, clinical presentation, and therapeutic advances in FM. This review will also highlight issues that are important to the oral health care provider, including orofacial manifestations and dental considerations for patients with FM.
