Although electromyography (EMG) has been used extensively in dentistry to assess masticatory muscle impairments in several conditions, especially temporomandibular disorders (TMDs), many investigators have questioned its psychometric properties and accuracy in diagnosing TMD.

Surface electromyography (sEMG) is a diagnostic tool that ensures reliable and valid evaluation of muscle activity. sEMG detects electrical potentials and on this account may conceivably be employed in the TMD recognition.

An EMG evaluation of masticatory muscle function in TMD subjects provides a basis for diagnosing the disease, monitoring its progression and measuring the effectiveness of treatment. Numerous studies have shown that patients with TMD exhibit alterations in masticatory muscle EMG activity either as a result of the disorder itself or due to a ...

2022年2月1日 · The EMG signal is analysed in order to identify an instability disorder in TMJ. A methodology based on SOM combined with Cross-correlation is proposed. The approach allows one to classify subjects based on TMJ muscles activity.

The Authors have described a clinical case involving a patient with a classical TMJ syndrome and a full range of typical symptoms, both dental and non-dental. The patient underwent a set of EMG tests before his occlusal plane was restored using a …

A new approach for the detection of Temporomandibular joint disorders (TMDs) from the recorded electromyography (EMG) signals from the muscles around the temporomandibular joint (TMJ) has been presented in this paper. Multivariate Autoregressive (MVAR) modelling has been applied to a six-channel set …

One of the primary uses of EMG in dentistry is to diagnose and monitor TMJ (temporomandibular joint) disorders. TMJ disorders affect the jaw joint and can cause pain, clicking, or restricted movement. By measuring the electrical activity of the muscles around the jaw, dentists can identify abnormal patterns that contribute to TMJ issues.

Nineteen patients with unilateral TMJ osteoarthritis without masticatory muscle pain and 20 control subjects were evaluated. We measured EMG amplitudes at maximum voluntary contraction, median frequency from the EMG power spectrum during sustained clenching at 70% and PPTs before and after the clenching in both temporalis and masseter muscles.

2014年1月31日 · Electromyography (EMG) of masseter and anterior temporalis muscles was performed during mandibular rest position. In the treated group, the occlusal appliance reduced the electrical activity of the analyzed muscles at right and left sides (p<0.0001), and equilibrated muscular activity between right and left sides (p<0.0001), reaching values ...

EMG has several uses in general dentistry within our practice, including orthodontics, implants, occlusion or bite correction, and TMJ disorder or sleep disorders. In dentistry for the last few decades, EMG are used in several purposes such as assessing muscles of the head and neck at rest and in function.
