Smaller-diameter nerve fibers are indeed more sensitive to local anesthetics, making them easier to block with supraperiosteal injections. Larger-diameter nerve fibers, such as those in the inferior alveolar (IA) and posterior superior alveolar (PSA) nerves, require a larger volume of anesthetic for effective blockage.
