Description

Dental clinics must sometimes treat patients who complain of foul breath but do not in fact have it. They can be perplexing for dentists. Such patients typically have depression, delusion of reference and poor social adaptation in addition to this false conviction of the foulness of their own breath. Such patients are diagnosed as having “phobia of emitting foul odor (mouth odor type)”. In this report, we developed a screening test to identify patients with this syndrome from among those complaining of foul breath, and evaluated the usefulness of this test.<BR>The test consisted of a self-rating questionnaire, developed in cooperation with both dentists and psychiatrists. Composed of 10 items, it mainly rated the intensity of the belief in emitting foul breath, delusion of reference and disturbance of social adaptation.<BR>The total score in the test ranged from 10 to 45. The higher the score, the higher was the probability of the patient having the syndrome.<BR>This test was performed on 27 patients diagnosed as having “phobia of emitting foul breath” and the control subjects were patients who complained of foul breath and actually had it, (their mouth odors were diagnosed as being due to diseases of the oral cavity such as periodontitis). The average scores for each item and total scores of the patients were significantly higher than those of the control subjects.<BR>It was concluded that a cut-off point of 21/22, at which the sensitivity was 0.93 and specifi city 1.00, should be used.
