Sterilized single-use needles with gamma rays for dental anesthesia. Manufactured in accordance with European regulations and subjected to strict quality controls. The cannulas are made of stainless steel, ultrasonically welded with a triple-beveled tip and a silicone coating that allows for easier penetration into the tissue, while simultaneously reducing pain and trauma. The production batch, expiration date, and size are indicated on each needle for easy identification. An indicator point in the center allows the practitioner to quickly distinguish the orientation of the bevel.
