Aspirating syringes are used to inject a local anesthetic when performing surgical dental procedures. Unlike traditional syringes,the aspirating syringe injects anesthetic from a carpule, such as Septocaine, articaine, and epinephrine, and allows the dentist to aspirate the injection site by pulling the thumb ring outward. This important step ensures that you do not hit a blood vessel or artery when injecting the anesthetic. Inversely, pushing the thumb ring inward allows the anesthetic solution to pass through the needle. Henry Schein offers autoclavable, stainless steel aspirating syringes for both metal and plastic hub disposable needles.
