No-Needle dental shot could spare kids pain and fear
NCT ID NCT07548892
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares a needle-free injection system to a traditional dental syringe for numbing children's teeth before extraction. About 60 healthy kids aged 6 to 12 will be randomly assigned to one method. Researchers will measure their anxiety, pain, and vital signs to see if the needle-free approach is less stressful.
