Summary
This trial tests whether photobiomodulation—a type of low-level laser therapy—can reduce pain 24 hours after orthodontic spacers are placed. Twenty-five people aged 13 to 30 who need braces will receive the laser on one side of the mouth and a sham treatment on the other. Pain levels, temperature, and quality of life will be measured over three days.
