    Air turbine hand pieces can run up to 500,000 rpm, although they are rarely used at such high speeds. General operating speeds are 20,000–50,000 rpm varying with the diameter of the bur. The burs used at high speeds are mainly diamond coated or made of tungsten carbide. High speeds are used in the removal of enamel, dentine, and old fillings.

    Air is a mixture of gas, and solid and liquid particles. Energy from the sun heats up the atmosphere and the Earth unevenly. Cold air contains more air particles than warm air. Cold air is therefore heavier and sinks down through the atmosphere, creating high pressure areas. Warm air rises through the atmosphere, creating low pressure areas.
