Could a vibrating massager take the sting out of dental needles for kids?
NCT ID NCT07682181
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study tests whether a vibrating facial massager, used alongside numbing gel, can reduce pain and anxiety from dental injections in children aged 4 to 12. The idea is that vibration distracts the brain from pain signals, based on the Gate Control Theory. Children will report their pain using a faces scale, and heart rate will be measured as a sign of stress.
