Effects of Low-Level Laser Therapy on Oral Mucosal Wound Healing and Systemic Oxidative Stress in Diabetic Rats: An In Vivo Experimental Study

What the authors concluded

LLLT significantly accelerated oral ulcer closure and showed between-group differences in redox markers. In healthy rats, LLLT increased wound closure on day 7 (p = 0.018). In diabetic rats, LLLT improved closure on day 3 (p = 0.035) and on day 7 (p = 0.001). Across groups, oxidative markers differed significantly (e.g., TOS on day 10 overall, p = 0.011; OSI on day 10 overall, p = 0.047; SOD p

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 6 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
