Summary

This study tests whether cooling the injection site with an ice pen, applying a numbing spray, or using both together can reduce pain from dental anesthesia needles. About 192 adults needing a standard dental injection will be randomly assigned to one of four groups: ice alone, spray alone, both, or no pre-treatment. Participants will rate their pain right after the needle goes in, and researchers will also observe their reactions.
