As the speed of a handpiece increases, its torque subsequently decreases (slow-speed handpieces have high torque, whereas high-speed handpieces, like the air turbine system, have a low torque) The free running speed of 1:5 gear ratio electric handpiece is the same as its cutting speed; thus, 40,000 motor speed x 5 = 200,000 rpm burr speed.
For instance, a latch type, or right angle bur, is only used in the slow-speed handpiece with contra-angle attachment. A long shank or shaft is only used in slow speed when the contra-angle is not in use, and finally, a friction grip bur, which is a small bur, is used only in the high-speed handpiece.
Prophylaxis: dental prophylaxis includes the removal of extrinsic staining using a slow-speed rotary handpiece and a rubber cup with abrasive paste, mostly containing fluoride. [21] The abrasive nature of the prophy paste, as it is known, acts to remove extrinsic staining using the action of the slow-speed handpiece and the paste against the tooth.

HCMOS ("high-speed CMOS") is the set of specifications for electrical ratings and characteristics, forming the 74HC00 family, a part of the 7400 series of integrated circuits. [ 1 ] The 74HC00 family followed, and improved upon, the 74C00 series (which provided an alternative CMOS logic family to the 4000 series but retained the part number ...
