Bone repair assessment of critical size defects in rats treated with mineralized bovine bone (Bio-Oss®) and photobiomodulation therapy: a histomorphometric and immunohistochemical study

What the authors concluded

At 60 days, groups L and C displayed the highest proportion of bone neoformation. However, group B+L had more than twice as much bone neoformation as group B at 30 days. These findings indicate the positive role of PBM in the early stages of bone regeneration. In addition, TRAP immunostaining occurred later in group L, demonstrating a possible association of PBM with positive bone metabolism.

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 45 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.
