The effects of relaxation/imagery training on recurrent aphthous stomatitis: a preliminary study.

Abstract

Recurrent aphthous stomatitis (RAS) is one of the most common diseases of the oral mucosa. Although etiology remains unknown, immunological and emotional disturbances have been implicated in the pathogenesis of RAS. No consistently effective therapeutic regimen has been found. The present study investigates the voluntary modulation of RAS employing hypnosis-like relaxation/imagery training procedures. A multiple baseline design was used to evaluate change in frequency of ulcer recurrence. The role of psychological distress, ratings of perceived pain, and hypnotizability in the treatment of RAS were also examined. Results suggest that the relaxation/imagery treatment program was associated with a significant decrease in the frequency of ulcer recurrence for all subjects. Psychological distress was examined for relationship to ulcer recurrence and symptomatic changes with treatment, but no pattern was found. Finally, little support was found for the role of high hypnotic ability in the treatment of RAS.
