Results of a dental fear survey in Japan: implications for dental public health in Asia.

The purpose of this investigation was to initiate the study of dental fear in Japan. 415 college students, aged 18-22 yr were surveyed. A standardized questionnaire which has been used in the United States was translated into Japanese and was administered to the students. More than 80% of those surveyed reported some dental fear. Six to 14% of the students reported extreme fear of the dentist. The majority of the subjects admitted that they delayed making dental appointments due to fear. Muscle tension was the most common physiological symptom reported. The dental drill and needle were the most fear-provoking stimuli.
