About

The aim of this study was to evaluate masticatory muscle electrical activity in patients with pain-related and pain-free temporomandibular disorders (TMD) as well as in subjects with no TMD. Ninety children with mixed dentition were recruited to the study. Of this total, 30 subjects were diagnosed with pain-related TMD, 30 with pain-free TMD, and 30 without TMD. We used Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD) to assess the presence of TMD in the examined children. The electromyographical (EMG) potentials of the temporalis and masseter muscles were measured with a DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) at rest and during maximum voluntary clenching (MVC).

Enrollment: 90 patients

Sex: All

Ages: 7 to 12 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• mixed dentition (the subjects should be aged between 7 and 12 years)
• consent to participate voluntarily in the study

Exclusion criteria

• subjects who had undergone orthodontic or masticatory motor system dysfunction treatment, had systemic or rheumatologic diseases, a history of mouth breathing, surgery, traumas or malformations in the head and neck region

Trial design

90 participants in 3 patient groups

TMD-pain group

Description:

The TMD-pain group consisted of 30 children aged between 7.1 and 12.3 with a pain-related TMD diagnosis. All the patients in the TMD-pain group had myogenous or arthrogenous TMD according to the RDC/TMD protocol.

Treatment:

Diagnostic Test: electromyography

pain-free TMD group

Description:

The pain-free TMD group consisted of 30 children between 7.3 and 12.6 years of age. To be included in the pain-free TMD group the participants had to meet Axis I of the RDC/TMD criteria for a pain-free diagnosis.

Treatment:

Diagnostic Test: electromyography

non-TMD group

Description:

The non-TMD group comprised 30 children aged between 7.2 and 12.5 without any recognised TMD based on RDC/TMD, Axis I.

Treatment:

Diagnostic Test: electromyography
