Sustained and Repeated Mouth Opening Leads to Development of Painful Temporomandibular Disorders Involving Macrophage/Microglia Activation in Mice

Temporomandibular disorder (TMD) is a set of heterogeneous musculoskeletal conditions involving the temporomandibular joint (TMJ) and/or the masticatory muscles. Up to 33% of the population has had at least one symptom of TMD with 5-10% of them requiring treatment. Common symptoms include limited jaw movement, joint sound, and pain in the orofacial area. Once TMD becomes chronic, it can be debilitating with comorbidities that greatly reduce one's overall quality of life. However, the underlying mechanism of TMD is unclear due to the multicausative nature of the disease.

Prevalence of TMD in Sjӧgren Syndrome Patients

Sjӧgren's Syndrome seems to play a role in temporomandibular joint disorders.

Early Molecular Response and Microanatomical Changes in the Masseter Muscle and Mandibular Head After Botulinum Toxin Intervention in Adult Mice

The Botox-injected masseters had greatly increased expression of genes involved in muscle atrophy at the 1 week time point compared to the control side muscles. At the end of the study, 2 weeks after injection, the Botox-injected masseters were about 20% smaller than the control side masseters, and the Botox-side condyles had lost about 40% of relative bone area compared to the control side condyles.

Centralized Pain in TMD: Is It All in the Head?

We are pleased to introduce Sophia Stone, a new contributor to The TMJ Association, whose passion is to separate TMD fact from TMD fiction. Sophia has a background in medicine and research and can draw on her personal experience as a TMD patient.

TMD and Burning Mouth Syndrome

A study in the International Journal of Dental Research reporting the latest update on Burning Mouth Syndrome (BMS) noted two thirds of BMS patients also had Temporomandibular Disorders (TMD).

Stem Cell Study of Jaw Development Could Offer Insight Into Craniofacial Flaws

Scientists in the USC Stem Cell laboratory of Gage Crump have revealed how key genes guide the development of the jaw in zebrafish. These findings may offer clues for understanding craniofacial anomalies in human patients, who sometimes carry a mutation in equivalent genes.

Pain in Your Head Hurts More Than Elsewhere in the Body

Terrie Cowley, Co-Founder and President of The TMJ Association, often remarks that patients tell her that the pain they feel in their jaws is worse than pain elsewhere in the body.

Hyperreactive Brain Network May Be Cause of Chronic Pain in Fibromyalgia, Study Suggests

Fibromyalgia is one of the overlapping pain conditions with TMD. This article appeared in Fibromyalgia News Today on January 15, 2018. A new study suggests a hyperreactive brain network may be the underlying cause of chronic pain in fibromyalgia.
