TITLE: Reduced or Painful Jaw Movement After Collision-Related Injuries


CITATION: JADA, Vol. 138, January 2007


AUTHORS: Linda Carroll, PhD, Robert Ferrari, MD, FRCPC, J. David Cassidy, PhD, DrMedSci Department of Public Health Sciences, School of Public Health, University of Alberta, Edmonton, Alberta Canada.


The article was published in the Journal of the American Dental Association and is one of the most recent manuscripts on jaw dysfunction and Whiplash-Associated Disorders (WAD). This article examined data from a large, population-based group of people who filed collision-related personal injury claims to report the frequency of reduced or painful jaw movement after an injury related to a collision. The study identified personal characteristics, crash related factors and post injury symptoms associated with the onset of reduced or painful jaw movements with WADs.


The results of this study showed that within the WAD injuries, the onset of reduced and/or painful jaw movement was associated with:


1: Females

2: < 50 years of age

3: having hit one’s head in the collision

4: post injury symptoms of difficulty swallowing, ringing in the ears, dizziness and intense neck pain.


“It was determined that reduced or painful jaw movement was more common in people with WAD than in those with other collision-related injuries.” (Carroll, Ferrari, & Cassidy, 2007, p. 86)
