Outline of Final Research Achievements

Patients in dental clinics perceive the bone-conducted sound via the teeth in addition to the air-conducted sound from the ear during the drilling of their teeth. In order to reduce the discomfort during treatment, it is necessary to find the characteristics of both the air-conducted and the bone-conducted dental drilling sounds. the bone-conducted sound was measured during the drilling of the artificial teeth. As the result, high frequency components up to 20 kHz in the bone-conducted dental drilling sound were observed.
