Effects of Dexamethasone and Low-Level Laser Therapy on Pain, Swelling, and Quality of Life After Buccal Fat Pad Removal: A Clinical Trial

What the authors concluded

There were no differences between the LLLT and DXM groups in pain or edema. In terms of the QOL, the LLLT group was significantly more comfortable when chewing than the DXM group (P < .05). The use of LLLT at a power of 100 mW and 2 J/cm2 per point had similar effects to oral DXM for the control of pain and edema, as well as in the QOL, except for masticatory function, which was significantly be

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 2 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.
