Abstract

This study investigates the relationship between reported bruxism, recurrent headaches and signs o f TMJ dysfunction. 244 consecutive patients attending the Examination and Emergency Primary Care Unit for dental treatment, were examined for signs of TMJ dysfunction. The patients also completed a questionnaire which determined the prevalence o f recurrent headaches and habitual bruxism. Results were analysed using cross-tabulation to obtain chi-square values to investigate associations between reported bruxism, recurrent headaches and TMJ dysfunction. There was a highly significant relationship between: TMJ and masticatory muscle pain and recurrent headaches (p<0.005); Reported bruxism and TMJ and masticatory muscle pain (p<0.001), and a significant relationship between: Reported bruxism and recurrent headaches (p<0.05). The frequency o f the signs and symptoms provides support for closer liaison between dentists and other disciplines to provide improved education, treatment and research in the fields of headaches and orofacial pain.
