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.

Brittani's Story

  • May 13, 2015

My TMJ problems started when I was 13 years old. We're not 100% sure what started it, but my doctors think it was a combination of me already having Juvenile rheumatoid arthritis and the fact I had my fourth open heart surgery and I was intubated for a long amount of time.
 
After the surgery my jaw started clicking and it started to hurt a lot. About three months later, I was back to school, eating lunch with my friends and my jaw locked open. I started freaking out, my friends rushed me to the school nurse and she drove me to the ER. This would soon become my life.
 
From the ages of 13 to 17 my jaw locked open about 300 times. A part of my jaw bone formed a chip and when it would lock, it would lock right into the chip. I would have to be sedated at the ER each time it would lock. My head was wrapped with Co-flex [flexible bandages] days after, just to keep it in place. Off and on it would get so bad I had to be home-bound, because I was going to the ER so often and the pain was so bad. I was on Vicodin and a muscle relaxer.
 
I've had my mouth wired shut two times. I've had both sides shaved down twice and then my most recent surgery was three years ago when implants were put into each side. They worked well for three years; but as of the past six weeks, my implant on the right side is now moving.
 
I live in Illinois and, as of July 1st, dental isn't covered either by Medicare or Medicaid. Everything I ever had with my TMD was always covered, which I'm thankful for, but now I'm worried what’s going to happen. I don't want to know what the pain is like when my jaw locks with the implant still in, and I don't agree that TMD is dental. I have a heart and lung illness− one lung and a long list of issues with that. Even with all of this, TMD is the most annoying.
 
I didn't do a lot from the ages of 13 to17, because I was afraid of having fun. I'd laugh and it would lock. Now it is starting again and my doctor won't give me any good pain meds, other than Advil. I guess she doesn't get that a titanium implant moving inside my jaw is quite painful. Eating anything other than soft foods and soup is out of the question. I'm hoping so much I can get this fixed ASAP!
