Light stimulation makes bones heavier — ScienceDaily

Osteoporosis is a disease in which bone loses mass as a result of age or other influences. This weakening is the leading cause of fractures in the elderly, often after trivial injuries, and makes treating these “pathological fractures” a challenge. Bone health is a dynamic process of continual remodeling controlled by multiple factors. Sclerostin, a glycoprotein coded by the gene SOST, is produced by bone cells and suppresses bone formation. Now, researchers at Tokyo Medical and Dental University (TMDU) have shown that laser irradiation, by inhibiting sclerostin expression without inducing inflammation, shows promise as a new treatment modality for osteoporosis.

Lasers have been used in medical and dental practice for their beneficial photo-biomodulation effects on tissue healing. The benefits of low-level laser therapy are now gaining increased attention in spheres of medicine and dentistry that require enhanced bone regeneration.

The team knew that in periodontal surgery, bone that underwent controlled
