Abstract
Temporomandibular disorders (TMDs) comprise a number of clinical conditions
characterized by changes in masticatory muscles, temporomandibular joints (TMJ) and associated
structures. According to researches in the U.S. and Europe, chronic orofacial pain encompasses
40 % of all chronic pain conditions, of which 10-15 % is related to the TMD. Pain and
sensitivity of masticatory muscles and TMJ are most prominent symptoms of TMD. Although
the etiopathogenesis of TMD has not been fully elucidated, in patients with TMD were observed
changes in the processing of painful stimuli, indicating the importance of ion channels
in the development of craniofacial painful conditions. Ion channels seam to regulate neuronal
excitability. Since sensory inputs from craniofacial region are transmitted to higher neural
centers responsible for pain sensations through trigeminal ganglion (TRG) neurons, changes in
expression of various ion channels in TRG neurons might be causative in development of
TMD.
