Dental Syringe

BusinessMed® Dental Syringes are reusable cartridge syringes for dental local anesthesia: a cartridge of anesthetic goes into the barrel, a needle is threaded onto the tip, and the thumb ring drives the plunger. Most cartridges hold 1.8 ml, the size named on several of our syringes, with handle and grip variations between models.

How a dental cartridge syringe works

In the most commonly used design, the breech-loading aspirating syringe, the cartridge is loaded through an opening in the side of the barrel. A harpoon on the end of the plunger engages the rubber stopper of the cartridge, so the stopper can be drawn back as well as pushed — this is what makes an aspirating dental syringe. Check each product listing for its loading and aspiration type.

How to choose a dental anesthetic syringe

  • Cartridge size. Match the syringe to the cartridges the practice stocks; most hold 1.8 ml, some 1.7 ml.
  • Aspirating or not. A harpoon on the plunger is needed for aspiration; check the product listing before ordering.
  • Grip. Thumb ring and finger-grip shapes differ between dental syringes; pick the one that sits best in the hand.

Care of reusable syringes

Reusable syringe dental teams use are cleaned and autoclaved after each patient; the harpoon and piston are replaced when they wear.
