Dental syringe

From Wikipedia, the free encyclopedia

A dental syringe is a syringe used by dentists for the injection of an anesthetic. It consists of a breech-loading syringe fitted with a sealed cartridge containing anesthetic solution.

The ancillary tool (generally part of a dental engine) used to supply either water or air to the oral cavity for the purpose of cleaning debris away from the area the dentist is working on, is also referred to as a dental syringe. A 3-way syringe has separate internal channels supplying air, water or a mist of air and water, created by combining the pressurized air with the waterflow. The syringe tip can be separated from the main body and replaced when necessary.
