ASPIRATING  SYRINGE  
This syringe is used in dentistry to inject a local anesthetic.  The aspirating  syringe  differs  from  most syringes in that it is designed to inject anesthetic from a carpule. The parts of an aspirating syringe consist of a threaded tip where the needle attaches, a barrel  where  the  carpule  is  placed,  a  piston  rod (plunger)  with  a  harpoon  attached  that  embeds  itself into the rubber stopper of the carpule, a finger grip, and a thumb ring . The harpoon allows the dentist to aspirate (draw back) the injection site to see if the needle tip is located in a blood vessel before injecting the anesthetic solution. Once the harpoon is engaged into  the  rubber  stopper  of  the  anesthetic  carpule,  the dentist  can  apply  inward  or  outward  pressure  on  the stopper by exerting pressure on the thumb ring. Pulling the thumb ring outward also pulls the plunger outward producing  an aspirating  effect;  whereas,  pushing inward   forces   the   anesthetic   solution   through   the needle.

ASPIRATING  SYRINGE  NEEDLE
The   aspirating   syringe   needles   used   in dental  treatment arrive sterile and are disposable. They are designed for a single use, and are available in different gauges and lengths. The gauge of a needle refers to the diameter of the hollow shaft of the needle. The larger the  gauge,  the  smaller  in  diameter  the needle.   The   lengths   of   the   needles   vary,   and   are classified as long (L) or short (S). Each needle  has  either  a  plastic  or  metal  hub designed to screw onto the threaded end of the syringe. This hub is positioned to permit the needle to extend inward to penetrate the rubber seal portion of a loaded anesthetic carpule. The  plastic  caps  covering  the  sterile  needle  are easily  removed  from  both  ends.  When  placing  the needle  onto  the  syringe,  remove  only  the  cap  that covers the syringe end on the needle. This maintains the sterility  of  the  needle  portion  used  to  inject  the patient. Normally, you prepare the anesthetic syringe with a  short  needle  (13/16  inch  in  length)  for  maxillary injections, and a long needle (17/8 inches in length) for mandibular  injections.  The tip of  the  needle  has  a beveled angle, which is turned toward the alveolus to accurately deposit the solution.
