I read “Effects of the GaAlAs diode laser (780 nm) on the periodontal tissues during orthodontic tooth movement in diabetes rats: histomorphological and immunohistochemical analysis”. Gomes, M.F., da Graças Vilela Goulart, M., Giannasi, L.C., et al. Lasers Med Sci (2017) 32: 1479.  https://doi.org/10.1007/s10103-017-2268-9.

Congratulations on the publication of your article. I would like to make a comment as to energy density of 640 J/cm2 was applied in an exposition time of 40 s. Is this value correct? This parameter seems to be wrong. Low energy or high energy can express stimulatory effect or inhibitory effect on the rate of orthodontic tooth movement [1, 2].

Thank you for publishing this interesting paper.
