===Dental syringes===
A dental syringe is used by [[dentist]]s for the injection of an [[Dental anesthesia|anesthetic]].<ref name="auto">{{cite web|url=https://www.drugs.com/monograph/lidocaine-hydrochloride-local.html|title=Lidocaine Hydrochloride (Local) Monograph for Professionals - Drugs.com|url-status=live|archive-url=https://web.archive.org/web/20170729055253/https://www.drugs.com/monograph/lidocaine-hydrochloride-local.html|archive-date=2017-07-29}}</ref> It consists of a [[breechloader|breech-loading]] syringe fitted with a sealed cartridge containing an anesthetic solution.

In 1928, [[Bayer]] Dental developed, coined and produced a sealed cartridge system under the registered trademark Carpule<sup>®</sup>. The current trademark owner is [[Heraeus#Heraeus Kulzer|Kulzer Dental]] [[GmbH]].

The carpules have long been reserved for [[anesthesia|anesthetic]] products for dental use. It is practically a bottomless flask. The latter is replaced by an [[elastomer]] plug that can slide in the body of the cartridge. This plug will be pushed by the plunger of the syringe. The neck is closed with a rubber cap. The dentist places the cartridge directly into a [[stainless steel]] syringe, with a double-pointed (single-use) needle. The tip placed on the cartridge side punctures the capsule and the piston will push the product. There is therefore no contact between the product and the ambient air during use.

The ancillary tool (generally part of a [[dental engine]]) used to supply water, compressed air or mist (formed by combination of water and compressed air) to the oral cavity for the purpose of irrigation (cleaning debris away from the area the dentist is working on), is also referred to as a dental syringe or a dental irrigation nozzle.

A 3-way syringe/nozzle has separate internal channels supplying air, water or a mist created by combining the pressurized air with the waterflow. The syringe tip can be separated from the main body and replaced when necessary.

In the UK and Ireland, manually operated hand syringes are used to inject [[lidocaine]] into patients' gums.<ref>{{cite journal|title=Use of safety dental syringes in British and Irish dental schools|first1=J.
