Clinical Trial Comparing Pain Perception in Children Using Two Different Local Anesthesia Tools

The goal of this clinical study is to learn whether the Super Pen (SP) device can reduce pain during local anesthesia (LA) infiltration for primary teeth compared to the conventional syringe (CS) in children aged 6-12 years. It will also explore factors that influence children's pain perception and their preferences for the anesthesia delivery method. The main questions this study aims to answer are: * Does the Super Pen (SP) reduce the pain experienced during LA infiltration compared to the conventional syringe (CS)? * How do factors such as age, sex, and arch treated (maxilla or mandible) influence children's pain perception when using the SP? * Which method-SP or CS-do children prefer during LA infiltration? Participants will: Receive local anesthesia using both the SP and CS techniques in a split-mouth design. Have their pain responses assessed using self-reported, behavioral, and physiological measures. Indicate their preference for either technique after both experiences.
