A collection of light therapy research articles on the benefits of light therapy use for teeth & dental applications.
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 radiation are synonymous; they all refer to light therapy.
LLLT After Wisdom Teeth Surgery: Evaluation of Immunologic Markers (Secretory Immunoglobulin A and Lysozyme Levels) and Thermographic Examination: Placebo Controlled Study.
May 16, 2017
This study investigated the effect of LLLT on pain & inflammation connected with surgical removal of impacted molars. It found that light at 830nm (infrared) penetrates to deep tissues and had a positive effect on pain & inflammation.
Evaluation of the effectiveness of the photobiomodulation in the treatment of dentin hypersensitivity after basic therapy. A randomized clinical trial.
May 1, 2017
This randomized clinical trial found that red light (660nm) significantly reduced dental discomfort immediately after treatment, and continued to demonstrate a decrease for the duration of the study without detrimental side effects.
Immediate and short-term effects of phototherapy on pain, muscle activity, and joint mobility in women with temporomandibular disorder: a randomized, double-blind, placebo-controlled, clinical trial.
June 11, 2017
This randomized, double-blind, placebo-controlled clinical trial found that a single session of phototherapy can reduce pain intensity in patients with TMD, indicating that light is an effective modality in the intervention of pain symptoms and increasing the comfort of patients immediately.
Light therapy stimulates dental stem cells
Light therapy has been used for decades in the field of dentistry for many different applications. This study looked at dental stem cells following the application of light therapy and found there to be a stimulatory effect on the proliferation of these cells.
