1, 145 cases with halitosis who visited our clinic (Department of Oral Surgery, Tokyo Medical College) were classified into 2 groups (objective halitosis: OH and subjective halitosis: SH). SH was divided into 2 sub-groups according to social adaptation type; psychosomatic halitosis (PH) had good adaptation and neurotic halitosis (NH) had poor adaptation. SH (NH) was more frequent groups, and females outnumbered males in all age. Oral disorder were found in 27.5%, primarily consisting of periodontal diseases, dental diseases, and glonitis. Systemic diseases included gastrointestinal tract, hepatopan creatobiliary and otolaryngological diseases as well as asymptomatic cerebral infarction (4.3%). In a QOL questionnaire, answers concerning social role and the meaning of life were disturbed in NH. PEG A patient evaluation grid (PEG) for differential diagnosis and treatment was designed based on these data. To cure intractable SH cases (25%), almost all of whom showed anthropophobia (96.0%), cognitive behavioral therapy was effective in 68.0%. Cognitive behavioral therapy appear useful in the treatment of intractable SH.
