作者： Barry j. SESSLE Department of Physiology Faculty of Dentistry University of Toronto Canada BDS BSc MDS PhD FRSC

Difficulties with the diagnosis and management of acute and chronic pain conditions stem largely from uncertainties of the aetiology or pathogenesis of the conditions. Recent studies have provided some important new insights into the peripheral and central processes underlying pain, and this presentation will review some of the recent advances in our knowledge of the neural processes involved in pain of the orofacial region.
