Dual-side Calasept Irrigation Needles are vented for irrigation during root canal therapy. These high quality, dual-side vented, luer lock irrigation needles are said to provide for safe and effective irrigation when performing endodontic treatment. Dual side vents optimize cleansing of canals, creating a “swirl-effect.” The closed tip safely protects the apex. They are available in a container packed box of 40 needles, choose 27g or 31g. Both sizes are bendable and have a luer lock hub.
