A questionnaire survey was conducted with 559 people and the relationship between the sound of a dental drill and dental anxiety level was examined. The following results were found. (1) There were individual differences in terms of unpleasant feeling to the sound of a drill and approximately half of the respondents felt the sound of a dental drill as unpleasant. (2) Those who answered that the sound of a dental drill was unpleasant tended to be more fearful of dental treatment than the other respondents. (3) The fear of the sound of a dental drill had a strong influence on dental anxiety level. (4) There were differences in unpleasant feeling for the sound of a dental drill between dental clinical students who were already trained to use the dental air turbine compared with the other respondents. These results suggest that it is necessary to take care of the sound of dental drills to reduce the fear of patients from visiting a dental clinic. The frequency spectra of airconducted sound and bone-conducted sound under dental treatment were previously measured and analyzed [8]. It was found that each sound included audible and ultrasonic frequencies. Ultrasound can be perceived through bone conduction [9]. Further research on the sound characteristics and quality of dental drills is being conducted.
