  • High-speed air turbine - British Dental Association

    2021-7-26 · High-speed air turbine. Prior to its development in the late 1950s drills had been driven by electricity. With the air turbine the burr is turned by air pressure and can reach speeds of up to 500,000 revolutions per minute. This speed generates a lot of heat which can cause irreparable damage to the pulp so the drill is always fitted with a ...
