25G SUS304 Stainless Steel Dental Irrigation Needle Tube , Lateral Notched Blunt Tip

A Dental Endodontic Irrigation Needle Tube is a precision micro-component used in root canal therapy (endodontics). It is a slender, cannulated tube designed to be attached to a syringe to deliver irrigation solutions into the pulp chamber and root canal system. The primary purpose is to flush out debris, disinfect the canal, and dissolve organic tissue without damaging the delicate dentin walls or extruding irrigants into the periapical tissue. This dental needle tube is manufactured from SUS304 Medical Grade Stainless Steel. It features a Lateral Notched design with a Blunt Tip. Unlike traditional open-end needles that spray directly from the tip, the lateral notch features a closed, rounded, and blunt tip with a laser-cut opening on the side of the cannula. This design is engineered for safety and efficiency, directing the flow of the irrigant laterally along the canal walls while preventing the high pressure that can force fluid through the apex of the tooth.

Main Using Areas:

  • Root Canal Irrigation
  • Debridement: Flushing out dentin chips and pulp remnants created during filing and reaming.
  • Lubrication: Applying to lubricate files and soften dentin.
  • Drying: Used with air or paper points to dry the canal before obturation.

Different Needle Points and Their Applications:

Needle Tip Type Design Primary Application
Lateral Notch (Side-Vent) Closed tip with one or two laser-cut side holes. Deep, safe irrigation. Best for delivering irrigants to the apical third without pressure buildup. Ideal for curved canals.
Open End (Bevelled) Standard hypodermic needle cut at an angle. High-flow flushing. Used in the coronal part of the canal. Not recommended for deep insertion due to risk of extrusion.
Double Side Ports Closed tip with two opposing side holes. Balanced irrigation. Provides even distribution of fluid to both lateral walls, preventing unilateral pressure.
Multi-Vented Closed tip with multiple small holes along the last few mm. Diffused irrigation. Spreads the fluid over a wider area, minimizing pressure on any single point of the canal wall.

Different Applications:

  • 30G (Thinnest): Used for fine and curved canals. Allows the needle to reach within 1-2mm of the working length for deep positive irrigation.
  • 27G / 25G: Standard sizes used for larger, straight canals (e.g., distal roots, premolars, anterior teeth). They offer a good balance between flow rate and accessibility.
  • 23G (Thickest): Used primarily for coronal irrigation to flush out gross debris before fine negotiation of the canal begins.
