What size needle used to inject lidocaine?
Only approach the patient after you've got the lidocaine in the syringe with a teeny-tiny needle at the end. Ideally a 27-30 gauge needle is best to minimize pain.
Which needle size is less painful?
Fine Needles
A significant reduction in pain and bleeding from use of a 33-gauge needle compared to a 31-gauge needle has been demonstrated. However, patient satisfaction was improved only after application of a suitable lubricant to the 33-gauge needle, which presumably reduced insertion force and workload.
Does a 25 gauge needle hurt?
These results indicate that when it comes to injection pain and needle gauge, size does not matter. There is no statistically or clinically significant difference between perceived pain of injection based on the needle gauges commonly used in dentistry.
What is 25 gauge needle used for?
For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections. Different sized needles are used for different purposes.
