27G 40MM Stainless Steel 304 Endodontic Irrigation Needle Tube , Notched Tip ISO9626
Dental Endodontic Irrigation Needle Tubes are slotted, side-vented needle tubes, which are mainly used to remove pulpal debris and microbes effectively from the root canal. The notched needle tips is designed for safe irrigation and tooth structure protection. These slotted irrigation dental needle tubes are suitable for using in root canal procedures and periodontal pockets, ranging from typically 27G, 30G. The flexibility of these dental needle tubes ensure the patient’s comfort. YUHONG GROUP is professional in medical grade stainless steel needle tubes and our needle tubes are an important metal part of medical needles, such as injection needles, infusion needles, veterinary needles, dental needles, AV Fistula needles, beauty needles, and so on.
