The study justifies the use of diabetic syringe with 30-gauge needle to be used for the delivery of LA using infiltration technique in child patients because smaller gauge needle is less painful; the size and the color of the syringe is such that it does not scare the child patient, cost-effective, and the calibrations at 0.025 mL intervals in insulin syringe provide a drug delivery control, which in turn reduces the pain caused and there is less tissue distension, less chances of local ischemia and necrosis. Here, INS is linked to ischemia.
