Effects of an intraoral device (IOD) on electromyographic activity on the masseter and temporal muscles in Class III patients.

Objective: Class III malocclusion is characterized by a loss of vertical dimension associated with muscle imbalance. The present study was designed to determine electromyographic amplitude changes in temporal (T) and masseter (M) at rest and during clenching in Class III patients treated with an intraoral device (IOD) over a 24-hour period for 30 days with transcutaneous electrical nerve stimulation (TENS).

Methods: Twelve patients with Class III (mean age 27.

Non-invasive joint decompression: An important factor in the regeneration of the bone marrow and disc recapture in temporomandibular arthropathies.

Background: This article aims to demonstrate the importance of the TMJ (Temporomandibular Joint) decompression in the treatment of degenerative processes and disc displacements, reporting two clinical cases treated with orthopedic and decompressive correction of TMJ.

Material And Methods: The studies reported in this article show patients with muscle and joint pain who were evaluated pre and post-treatment through MRI (Magnetic Resonance Irradiation) to follow-up bone marrow regeneration and TMJ disc placement. Transcutaneous electrical stimulation (TENS), measurement equipment and IO (Intraoral Orthotic) were used to evaluate and treat the patients.

Autoimmune temporomandibular arthropathy: diagnostic considerations.

The etiology of degenerative processes of the temporomandibular joint (TMJ) remains unclear, as they could be the result of trauma, infection, or autoimmune disease. Improving the diagnosis of autoimmune disease, whether the TMJ is the primary site or secondarily affected by a systemic disease, is of fundamental importance in selecting treatment that will address the causes rather than just relieve the symptoms. The purposes of this article are to discuss autoimmunity as an etiologic factor in degenerative processes of the TMJ by presenting clinical cases and to highlight the importance of imaging and serologic examinations for diagnosis.

Structural lesions of the TMJ in relation to Mycoplasma pneumonia infections.

Aims: The presence of different types of bacteria in the temporomandibular joint (TMJ) is considered an etiological factor in TMJ pathologies. Mycoplasma pneumonia (MP), for instance, can be present in different joint pathologies. The aim of the present study is to correlate pathognomonic imaging of the TMJ in nuclear magnetic resonance with laboratory tests for MP.

Stomatognathic system involvement in rheumatoid arthritis patients.

Aims: Temporomandibular joint (TMJ) and stomatognathic system involvement are usually observed during the course of rheumatoid arthritis.

Methodology: This article presents the findings during examination of 190 TMJs from rheumatoid arthritis (RA) patients, and 44 TMJs from controls without RA, including a description of signs and symptoms related to the stomatognathic system, radiological findings in hands-, and TMJ, erythrocyte sedimentation rate (ESR) values, and scores obtained in the Disease Activity Score (Das 28) and the Health Assessment Questionnaire (HAQ).

Results: The sample included 57.
