Causes of persistent joint pain after arthrocentesis of temporomandibular joint.
PURPOSE The present study was undertaken to elucidate the factors responsible for the failure of arthrocentesis to cure persistent joint pain in patients with nonreducing articular disc displacement in the temporomandibular joint (TMJ). PATIENTS AND METHODS Thirty-six patients with internal derangement of the TMJ were selected. Magnetic resonance imaging was used to examine the configuration ...
متن کاملMedullary dorsal horn neuronal activity in rats with persistent temporomandibular joint and perioral inflammation.
Studies at spinal levels indicate that peripheral tissue or nerve injury induces a state of hyperexcitability of spinal dorsal horn neurons that participates in the development of persistent pain and hyperalgesia. It has not been demonstrated that persistent injury in the orofacial region leads to a similar state of central hyperexcitability in the trigeminal system. The purpose of the present ...
متن کاملNociception and Conditioned Fear in Rats: Strains Matter
When using rats in pain research, strain-related differences in outcomes of tests for pain and nociception are acknowledged. However, very little is known about the specific characteristics of these strain differences. In this study four phylogenetically distant inbred rat strains, i.e. Wistar Kyoto (WKY), Fawn Hooded (FH), Brown Norway (BN) and Lewis (LE), were investigated in different tests ...
متن کاملThe Interface of Mechanics and Nociception in Joint Pathophysiology: Insights From the Facet and Temporomandibular Joints.
Chronic joint pain is a widespread problem that frequently occurs with aging and trauma. Pain occurs most often in synovial joints, the body's load bearing joints. The mechanical and molecular mechanisms contributing to synovial joint pain are reviewed using two examples, the cervical spinal facet joints and the temporomandibular joint (TMJ). Although much work has focused on the macroscale mec...
متن کاملCharacteristics of temporomandibular joint in patients with temporomandibular joint complaint.
INTRODUCTION This study was to investigate whether there was statistical difference between the bilateral temporomandibular joint (TMJ) in patients with unilateral TMJ pain or joint sounds, using cone beam computed tomography (CBCT). METHODS TMJ CBCT images of 123 cases were used to preliminarily determine the indicators suitable for the measuring method. TMJ CBCT image reconstruction was per...
