234 dentists and dental nurses were examined with a normal and a high-frequency audiometer in high standard clinical conditions. Their ordinary and high-frequency hearing as compared with the controls showed no significant differences. Thus, exposure to high-frequency noise from high-speed drills and other modern dental instrumentation does not appear to be harmful to one's hearing and does not necessitate audiologic screening procedures for dental personnel.
