Mechanisms of oral somatosensory and motor functions and their clinical correlates

Abstract

This article provides a review of somatosensory and motor pathways and processes involved in oral sensorimotor function and dysfunction. It reviews somatosensory processes in peripheral tissues, brainstem and higher brain centres such as thalamus and cerebral cortex, with a particular emphasis on nociceptive mechanisms. It also outlines some of the circuits and processes involved in reflexes and motor control. In addition, it emphasizes the concept of neuroplasticity and its applicability to oro-facial pain, to motor control and motor learning, and to adaptation to changes in the oral sensory environment such as may occur with the placement of dental implants. © 2006 Blackwell Publishing Ltd.
