Question

Quizplus · Accepted Answer

A long needle (usually 25-27 gauge and 32-42 mm in length) is commonly used to administer an injection of anesthetic on the mandibular arch for a block injection. This is because the injection site is located deeper in the tissues and requires a longer needle to reach the target area. A short needle may not be able to reach the required depth and may not provide adequate anesthesia.
