COMT (Catechol-O-methyl transferase) role in TMD – Wheaton dentist


New research has shown one of the genes that increases the likelihood of development of chronic pain.  COMT (Catechol-O-methyl transferase) enzyme degrades catecholamines such as dopamine, epinephrine, and norepinephrine in our brain and there are multiple variants of this enzyme.  COMT is associated with pain responsiveness and contains some combination of amino acids valine and […]

Placebo effect and why it works for some

Chemical reason some are more prone to placebo Scientists don’t know all the details but we do know that placebo treatments work for some issues (especially those that involve brain chemicals like dopamine and endorphins).  Examples of health problems that are altered by those chemicals include chronic pain (in my field that means TMD) and […]

Temporomandibular disorder TMD

Classification of TMD

Temporomandibular disorder TMD Temporomandibular disorders (TMDs) are characterized by pain in the muscles of mastication, the temporomandibular joint (TMJ), and/or the muscles associated with mastication in the head and neck.  Patients typically experience pain, limited opening, and/or clicking/popping of the TMJ joint.  This condition is much more common in females.  The severity of TMD ranges […]

TMD/TMJ surgery


TMD surgery seems to be making a resurgence after developing a poor reputation in the field many years ago. I think this is do to an advent of more and better microsurgical techniques. Arthroscopic lysis and lavage and arthroscopy showed excellent results in pain reduction and range of movement in 610 cases.  González 2011 Joint […]

TMD Research


Pre-orthodontic patients MRI study Ikeda JPros 2014 85% girls and 60% boys had some amount of disc displacement Correlated with age (longer alive means more chances for trauma) This was a pool of young patients so the high number is surprising TMD patient pool Dias 2012 Disc displacemnt in 59% TMJ’s (what is non-TMD percentage?) […]

Occlusal Dysesthesia or Phantom Bite Syndrome


Occlusal Dysesthesia or Phantom Bite Syndrome Occlusal Dysesthesia, also known as Phantom Bite Syndrome and Occlusal Hyperawareness, is not that uncommon.  Until I learned of this diagnosis these were just the “crazy” people that I would struggle to try to appease, without success.  I can personally think of 3 of my  patients that exhibit all […]

NTI Information


The NTI is an FDA approved occlusal splint (nightguard) designed to reduce muscle tension headaches and migraines.  All the information one would ever be interested in can be found on their website here.  Here is some research These are the muscles that are most effected by clenching and grinding Chronic symptoms of the head and […]

Orofacial pain


Orofacial pain experts A newer sub-specialty that I have great respect for.  They treat chronic patients without the dental blinders and are more in line with how the medical field treats chronic pain. Chronic pain arises due to the nervous systems neuroplasticity (Greene JADA June 2009).  Neuroplasticity is what allows us to learn and adapt […]

Night Guard Types – Different classes of Night Guards Classification of the night guard or occlusal appliance is shown below. 1. Anterior midline stop device (AMPS) This appliance is a small one that only contacts in the anterior.  Care needs to be taken that in protrusive and excursives the posteriors never can hit and the […]

Jay Shah and MTrPs


MYOFASCIAL PAIN: INTEGRATING OBJECTIVE PHYSICAL FINDINGS WITH TREATMENT STRATEGIES Jay P. Shah, MD 8:00 AM–4:00 PM (Break: 10:30–10:45 AM, Lunch: 12:00–1:30 PM, Break: 2:45–3:00 PM) Chronic pain states are characterized by profound changes in neuronal excitability and architecture in the pain matrix. This workshop integrates emerging knowledge the pain sciences in a clinically accessible way. […]
