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.

Chemical Material Composition:

Main Using Areas:

• Root Canal Irrigation: Delivering antimicrobial solutions deep into the root canal system.
• 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 (filling).

Different Needle Points and Their Applications:

Different Applications:

• 30G (Thinnest): Used for fine and curved canals (e.g., mesial roots of mandibular molars). 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.
