insert fluid in the device and follow the color coded instructions that allow for efficient use of the dental instrument. The device is so intricately sized that doctors are able to grip it well enough to get the job done. Some anesthetic syringes also include a power handle that gives the doctor less of a responsibility over the amount of pressure needed to push in the medicine because the power handle has settings that let the dentist set an amount for how much anesthetic they want to be produced. Dental handpieces Dental handpieces come in many various types which include: High-speed air driven (also known as an airotor), slow-speed, friction grip, and surgical handpiece. Dental laser A dental laser is a type of laser designed specifically for use in oral surgery or dentistry. The use of a laser can decrease morbidity after surgery, and reduces the need for anesthetics. Because of the cauterization of tissue there will be little bleeding following soft tissue procedures, and some risks of alternative electrosurgery procedures are avoided. Dental torque wrench A dental torque wrench or restorative torque wrench is a torque wrench used to precisely apply a specific torque to a fastener screw for fixation of an abutment, dentures, or prosthetics on a dental implant. Burs The cutting surfaces of dental burs are made of a multi-fluted tungsten carbide, a diamond coated tip, or a stainless steel multi-fluted rosehead. There are many types and classifications of burs. Some of the most common are: the round bur (sizes ¼ to 10) or inverted cone (sizes 33½ to 90L). Burs are also classified by the type of shank. For instance a latch type, or right angle bur, is only used in the slow speed handpiece with contra-angle attachment. Long shank or shaft is only used in the 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. There are many bur shapes that are utilized in various specific procedures. Operative burs Flat fissure, pear-shaped, football, round, tapered, flame, chamfer, bevel, end cut, bud bur, steel, inverted cone, diamond, brown stone, and green-stone Restorative instruments Excavators Spoon excavator: Used to remove soft carious decay Half hollenbach: Used to test for overhangs or flash Dental hatchers: Used to widen the entrance of the tooth cavity and slice away the thin carious
