Primary outcomePrimary: Pain Perception Measured by the Wong-Baker FACES Pain Rating Scale — 1.04; 4.24 score on a scale

Summary

The goal of this randomized clinical trial is to compare two different injection methods in children. The main question it aims to answer is: Is the needle-free injection method more painless than the traditional dental method? Two different methods will be used for children to perform anesthesia for extraction permanent molars.
