syringe (sirinj´),

n an apparatus of metal, glass, or plastic material consisting of a nozzle, or needle, barrel, and plunger or rubber bulb; used to inject a liquid into a cavity or under the skin.

syringe, air,

n a device by which air may be applied to a given area. An instrument supplied as part of the dental unit, consisting of a hand grip, nozzle, pressure-regulating valve, and hose connected to the compressed air supply.

syringe, air-water,

n a device that delivers pressurized streams of water and air for use in dental procedures.

syringe, aspirating,

n a type of hypodermic syringe used in local anesthesia that allows the user to confirm, in advance of delivering the anesthetic agent, that the needle has not entered a blood vessel.

syringe, aspirating, breech-loading,

n an aspirating syringe, used to deliver a local anesthetic agent, that is assembled by inserting the rubber stopper end of the anesthetic cartridge first toward the thumb ring, then the diaphragm end toward the needle opening before setting the harpoon and attaching the needle.

syringe, combination,

n a syringe that is usually part of the dental unit through which air, water, or a combination of the two may be delivered under pressure to the desired area.

syringe, hand air,

n an air syringe consisting of a metal tube bent at one end, terminating in a reduced diameter, and enlarged at the other end to engage a rubber bulb. The bulb is compressed by hand to supply a controlled spurt of air to a given area.

syringe, jet injector,

n a needle-free syringe that uses high pressure through small openings (jets) to administer a local anesthetic agent to oral mucosa.

syringe, nonaspirating

n a syringe that does not aspirate before the local anesthetic agent is deposited because it does not contain a harpoon at the end of the piston; this type of syringe should never be used during dental procedures because it is not possible to be certain of the exact location of the needle tip.

syringe, warm air,

n an air syringe equipped with an electric heating element to heat the air to any desired temperature.

syringe, water,

n a device, usually part of the dental unit, permitting controlled application of water to a given area. It has a flow control, pressure regulator, and heating element.
