Join Us AT TMJ Cafe

The TMJ Association is pleased to partner with Inspire to bring you the TMJ Cafe, a free online support network and discussion community for those with Temporomandibular Disorders (TMD). We invite you to meet others like you, share experiences and tips for getting through the day, and give and receive support.

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.

THE TMJ ASSOCIATION, LTD.

  • Oct 17, 2014

Founded in August 1986 by Terrie Cowley and Sandra Geilfuss, both sufferers of TMJ disorders, the mission of The TMJ Association, Ltd. (TMJA) is to improve the quality of health care and lives of everyone affected by Temporomandibular Disorders. The TMJA achieves its mission by:

  • Advocating for the needs of patients.
  • Promoting awareness of TMD among the public, policymakers, basic and clinical research and health care communities.
  • Encouraging basic and clinical research on TMD to provide greater understanding and safer and more effective methods of diagnosis and treatment, based on scientific evidence.
  • Periodically convening international scientific meetings to explore new findings and recommend promising lines of research to further the understanding of TMD.
  • Serving as a resource for the collection and dissemination of information on advances in research, treatment, insurance practices, patients’ rights, and legal and ethical issues.
  • Communicating with elected officials, government agencies, professional organizations, community leaders and other policymakers concerning TMD issues.
  • Benefiting from a prestigious Scientific Advisory Board for collaboration and consultation.
  • Collaborating with other patient advocacy organizations whose members experience conditions that overlap with TMD.

The TMJ Association was organized under the laws of the State of Wisconsin and earned a 501(c)(3) status in December 1989. As a nonprofit organization, The TMJ Association established an all volunteer Board of Directors. The Board established an all-volunteer Scientific Advisory Board to provide technical insight into the complex issues addressed by the Association.
