Methods: NDIS administers ¼ (0.45ml) of a cartridge volume at each step of injection.
Results: NDIS reduces the required injection force to 1/4th of conventional syringes. Lower injection rate and volume allow smoother administration of local anesthetics.
Conclusion: Patient’s pain is reduced since the balloon effect at site of injection is lowered. NDIS eliminates any possibility of the cartridge bursting during injection, which may happen when administrating conventional forceful injections. NDIS is autoclavable. It is registered as a new innovation in dentistry in Iranian National Patent Organization.
