Dental Syringe – Precision Aspirating Syringe for Local Anaesthesia Delivery

A Dental Syringe is a specialized metal syringe used to deliver local anaesthetic cartridges during dental procedures. Designed for precision, safety, and ease of use, this syringe is a critical tool in restorative dentistry, oral surgery, endodontics, periodontics, pediatric dentistry, and general practice.

Its stainless-steel, autoclavable body ensures durability and accurate control during injections, while the aspirating design improves safety by preventing accidental intravascular injection.

The dental syringe is typically made of high-grade stainless steel, featuring:

• Aspirating harpoon mechanism that engages with the rubber plunger of anaesthetic cartridges

• Finger and thumb rings for maximum control

• Smooth barrel for easy loading of 1.7–2.2 ml anaesthetic cartridges

• Autoclavable construction, ideal for repeated sterilization

• Compatible with standard dental needles (short/long)

It allows precise delivery of lidocaine, articaine, mepivacaine, and other dental anaesthetics.

Common types include:

1. Aspirating Syringe (Standard)

Most widely used; enables safe aspiration before injection.

2. Self-Aspirating Syringe

A spring mechanism automatically aspirates without pulling back.

3. Non-Aspirating Syringe

Simpler design; used less frequently in modern practice.
