2. To wash out or introduce fluid with a syringe.

air syringe

A syringe on a dental unit that delivers compressed air, water, or both through a fine nozzle to clear or dry an area or to evacuate debris from an operative field.


Use of high pressure may injure the tissues.

hand syringe

A hollow rubber bulb that is fitted to a nozzle and delivers air or fluid when squeezed; commonly called a bulb syringe.

hypodermic syringe

A syringe, fitted with a needle, used to administer drugs subdermally.

oral syringe

A syringe made of plastic or glass. It is not fitted with a needle but is graduated and is used to dispense liquid medication to children. The tip is constructed to prevent its breaking in the child's mouth. An oral syringe may also be used to deliver fluids to impaired patients with an intact swallowing mechanism.

water syringe

In dentistry, a syringe for delivering water spray to a localized area. The flow, pressure, and temperature are controlled.
Medical Dictionary, © 2009 Farlex and Partners


An instrument, consisting of a barrel and a tight-fitting piston with a connecting rod, used to inject or withdraw fluid. The barrel is usually calibrated in fluid units and the nozzle is shaped to fit a standard range of needles. Luer-lock syringes are designed so that the needle cannot be forced off by high pressure. Most modern syringes are plastic and disposable and are pre-sterilized and supplied in sealed containers.
