Resumo
Little is known about the physiological mechanisms related to low-intensity laser therapy (LILT), particularly in acute inflammation and subsequent wound healing. The objective of this study was to verify the effect of LILT
on mast cell degranulation. Epulis fissuratum tissues from
eight patients were used. One part of the lesion was
irradiated with an AsGaAl laser (λ= 670 nm, 8.0 J/cm2,
5 mW, 4 min). The other part was not irradiated. Then, the
specimens were immediately removed, fixed and examined
by light microscopy. The number of mast cells was similar in
laser-treated samples when compared with non-irradiated
specimens. The degranulation indexes of the mast cells
observed in the irradiated samples were significantly higher
than those of controls (P<0.05). LILT with the parameters
used increased the number of degranulated mast cells in oral
mucosa.
