Light Therapy Research – Inflammation

Research Banner

A collection of light therapy research articles on the benefits of light therapy use for inflammation.

NOTE: Researchers use several terms to describe “light therapy”. Photobiomodulation, low level light therapy (LLLT), phototherapy, photon therapy, photo energy, heliotherapy, and sometimes red, blue or (near) infrared (ir)radiation are synonymous; they all refer to light therapy.


Low-Level Laser Therapy After Wisdom Teeth Surgery: Evaluation of Immunologic Markers (Secretory Immunoglobulin A and Lysozyme Levels) and Thermographic Examination: Placebo Controlled Study.
