This program is one of five programs that were presented in an all day seminar titled "From Tooth to Migraine: The Trigeminally Mediated Disorders; Diagnosis, Treatment and Prevention." The goal of this program is to take the mystery out of the cause and progression of TM disorders and to make the evidenced based information useful in this regard. From pratical and relevent anatomy and physiology to the important concept of trigeminally initiated and mediated parafunction and parafunctional control, this 5-part program will attempt to separate fact from fiction. Diagnostically driven concepts will be thoroughly reviewed. Specific injuries that lead to both acute and chronic pain patterns will be described in terms of causes, diagnosis and treatment. It will be demonstrated that dentists can play a key role in magraine headaches as well as obstructive sleep disorders. In this third program, Dr. Glassman discusses the use of EMGs as a diagnostic tool for TM disorders.
