The purpose of this investigation is to develop a screening system for the high risk group for halitophobia. In 1999, the following were carried out : Oral examination, questionnairing, self-estimation for the gingiva condition. As the result of statistical analyses, it was shown that the students who self-estimate their gingiva conditions severely had following features : PMA scores were high (p<0.05), frequency of realizing the bleeding at the gingiva by brushing and the anxiety for bad breath were high (p<0.05), and life satisfaction was low (p<0.05). In 2000, measurement of bad breath by HalimeterTM (the volatile hydrosulphide measuring meter), detection of the coating of tongue score, questionnairing were carried out, and the relation of objective and subjective evaluation for bad breath was analyzed. As the result, students who were judged objectively having bad breath (VSC value≧ 150 ppb) were seldom aware of toothache by sweeteners or cold stimulation, and life satisfaction was lower (p<0.05). However, their subjective evaluation was not so high (p<0.05). And, students who were judged objectively not having bad breath were divided into 2 groups, one was with the anxiety for bad breath in conversation, another was without that. It was shown that students with anxiety have tendency to complain of other's bad breath (p<0.05), often aware of dryness of their mouth (p<0.05), and feel their daily lives stressful (p<0.05).
It is recognized that the halitophobia patients complain of dryness of their mouth. In this study, students who has realized their own bad breath without any objective bad breath tended to be aware of dryness of their mouth frequently, self-estimate for their gingiva condition severely, and feel stressful in the daily life. It was indicated that such features were useful as screening items of the high risk group for halitophobia.
