The outer diameter of the Octoplus needle is identical to that of a standard needle, but its inner diameter has been specially designed to inject the same dose of anesthetic liquid with lower pressure. This allows the dentist to better control their technique and the injected flow, resulting in a smoother injection experience for the patient. The Octoplus needle also offers additional advantages: thanks to a bevel indicator, the dentist can more accurately determine the injection site, reducing the risks of tissue damage as well as needle blockage.
