Effectiveness of low-level laser therapy in reducing pain perception of children during dental local anesthetic administration using laser acupuncture pen on the LI4 point: a randomized clinical trial.

Purpose: Laser acupuncture, a non-invasive variant of acupuncture, has been proven effective in the medical and dental fields. Hence, the present study aims to determine the effect of low-level laser therapy on the LI4 point, using a laser acupuncture pen, in reducing children's pain during local anesthetic (LA) administration.

Methods: Children in the age range of 8-12 years, in need of LA administration, were randomly assigned to two groups: Group I: laser acupuncture, Group II: control.
