Resumo
Although laser radiation is electromagnetic, its electric field polarization is rarely considered in photobiomodulation. This study compared the effects of laser polarization (parallel or perpendicular to the wound axis) with an electric field from a non-laser device on fibroblast migration and alignment. Human dermis fibroblasts were cultured, and a wound was inflicted. Cultures were evaluated under five conditions: parallel electric field(E//), perpendicular electric field(Epp), parallel polarized laser(L//), perpendicular polarized laser(Lpp), and control. All treatments increased cell migration compared to the control. Cells in the L// were more aligned after six hours, and those in the Epp group after 12 hours.
