Many dental and oral surgical procedures require the administration of regional (local) anaesthesia. Some may also require systemic sedation administered via intravenous methods. As such, dental needles are an intrinsic dentistry equipment requirement.
Administration of anaesthetics for dental or other types of medical procedures must be precise. Using the correct tool for the job is essential for patient safety, comfort, and optimal results. The selection of the needle to be used must be based on the practitioner’s expertise as well as the injection type and depth of penetration required.
Needles and syringes may be autoclavable or single-use – and modern clinics tend to generally favour single-use, disposable needles and syringes for optimal infection control.
Choosing the Right Anaesthetic Needle
The selection of the needle to be used must be based on:
- The type of injection to be performed
- The required depth of penetration
Dental needles are available in three lengths:
- Long – 32mm-41mm
- Short – average 22mm
- Ultra-short – as little as 12mm
The diameter of the lumen (or hollow tunnel) of the needle is its gauge. The gauge of the dental needle itself may vary, usually between 25G and 30G. (The higher the number, the smaller the gauge). The larger gauge needle is stronger, more rigid, and less prone to breakage or deflection within the deeper tissues.
Which needle is appropriate for use? The needle must be long enough so that it is never inserted to within 5mm of the hub. This point is the weakest part of the needle and it is more vulnerable to breakage here. (Furthermore, a broken needle without at least 5mm exposed outside the oral tissues is very difficult to retrieve.)
Mandibular blocks require the use of a long needle to obtain an adequate depth of penetration. Injections to the tissues and parts of the upper jaw near the tooth sockets and adjacent alveolar bone usually require shorter needles to avoid insertion too deep.
The choice of the correct needle is based on exacting medical science and human anatomy, and dentists are specifically trained in these intricacies.
Other types of Needles Dentists Use
Aside from the administration of anaesthesia, several other dental needles must be included when ordering dental supplies online. They include but are not limited to:
- Endodontic needles which are used for irrigation during root canal procedures
- Aspirating syringes are used to remove fluid and cells including blood, saliva, and pus; to create a vacuum, and to inject local anaesthetics. The plunger is pulled back after the needle is inserted and before the anaesthetic is injected, to ensure that the tip is positioned in the right place and has not punctured any blood vessels.
