Temporomandibular Joint Disorder with Electromyographic Evaluation in Different Age Groups.

Abstract

There are many subgroups of orofacial pain disorders. Temporomandibular disorders (TMD) are one of them, with identifiable signs like jaw opening and closing noises with small range of motion, or mandibular divergence during yawning as well as symptoms like tiredness in the muscle or jaw joint.Surface electromyography (SEMG) is a invasive and diagnostic tool that ensures effective evaluation of muscle activity of the external masticatory muscles called masseter and temporal muscles.Objective of this study is to  examine the muscular electrical activity recording of patients with temporomandibular joint disorder  is same for youngsters (below 30 years) and mid-age/old age (above 30 years).The number of statistically important pathological features in the stomatognathicsystemchanged with age in groups with TMJ disorders.
