Pain Reduction Using Vibration and Topical Anesthesia

Participants in this group received 20% Benzocaine Gel applied to the injection site for 5 minutes prior to local anesthesia administration. The gel acts as a topical anesthetic to numb the area and reduce pain perception during the injection procedure.

Participants in this group received vibration stimulation using a powered toothbrush applied to the injection site for 1 minute before the local anesthesia injection. The vibration works on the principle of gate control theory, aiming to disrupt pain signals and reduce discomfort during the injection procedure.
