Efficacy of Low-level Laser Acupuncture and Microcurrent Electrical Stimulation on Gag Reflex on Children

This study is testing two non-invasive techniques — low-level laser acupuncture and microcurrent electrical stimulation — to reduce the gag reflex in children who need dental impressions taken. A strong gag reflex can make routine dental procedures very difficult for some children. **You may be eligible if...** - You are a child without any systemic (whole-body) medical conditions or special health care needs - You show moderate-to-severe gagging during dental impressions - You score 2 or 3 on the Frankle behavioral rating scale (somewhat cooperative) - Your parent or guardian provides written consent **You may NOT be eligible if...** - You are currently taking anti-nausea medication - You have a known sensitivity to alginate (the material used in dental impressions) Talk to your doctor to see if this trial is right for you.
