Condition temporomandibular joint disorders
Treatments injection of 20% dextrose/ 0.2% lidocaine, injection of 1 ml of 0.8 sterile water /0.2% lidocaine
Phase phase 2/phase 3
Sponsor Chisel Peak Medical Clinic
Collaborator K. Dean Reeves, M.D.
Start date January 2013
End date March 2016
Trial size 40 participants
Trial identifier NCT01706172, TMJS


Dysfunction of the jaw, associated with pain in the jaw or about the jaw in the face can be quite long lasting and debilitating. Dextrose injection with a small needle has been notably helpful in preliminary studies in reducing pain and improving jaw function. This randomized trial will compare dextrose injection with sterile water injection for temporomandibular(jaw) dysfunction, also known as TMD.

Official title Treatment of Temporomandibular Dysfunction With Hypertonic Dextrose Injection: A Randomised Clinical Trial of Efficacy
Principal investigator W. Francois Louw, Doctor
Description Longitudinal studies of subjects with temporomandibular dysfunction show a general pattern of symptom diminishment, especially in the elderly. However studies out to 2-8 years show residual symptoms in many and nearly 25% with unabated symptoms. Dextrose injection has been utilized empirically for many years and a marked reduction in pain and luxation after intra-articular and pericapsular dextrose injection has been reported in a recent RCT. However, small study size and lack of a non injection control have prevented any definitive conclusions as the additional efficacy of including dextrose in the injectate. The mechanism of action of dextrose injection was originally thought to be via a brief stimulation of the inflammatory cascade with resultant production of growth factors. However, non-inflammatory dextrose effects on growth factor production have been demonstrated, and, more recently, dextrose has been found to treat neurogenic inflammation (pain from upregulation of the TRPV1 receptor on peptidergic nerves). This has the theoretical benefit of reducing pain, regardless of the status and position of the intraarticular cartilage or degree of degenerative change of the TMD. The primary goal of this study is to evaluate the ability of dextrose injection versus saline injection to reduce pain and improve functional complaints referable to the temporomandibular joint.
