Previous research has suggested a relationship between migraine pain and oral habits. The present study was designed as a replication of a prior study that found self-reported higher frequencies of certain oral habits in migraine as opposed to tension headache and non-headache groups. Three groups of subjects (common migraine, tension headache and non-headache) were given a single questionnaire in which five oral habits (i.e. teeth clenching, jaw jutting, cupping the chin in the hand, and resting the right and left side of the face on the hand) were rated on a 0 (not at all) to 10 (almost always) scale. Significant main effects were obtained for groups and oral habits in a 3 (groups) X5 (oral habits) ANOVA. Post hoc Tukey tests revealed the common migraine group reported significantly more frequent oral habits than did the tension headache group. The non-headache control group did not differ significantly from either headache group. Discussion focuses on the need for continued research in this area.
