The effect of laser therapy on the proliferation of oral KB carcinoma cells: an in vitro study.

Objective: The aim of this study was to assess the proliferative effect of carcinoma cells, strain KB, submitted to laser therapy with wavelengths of lambda685nm (31 mW; Ø; 0.38 cm(2), 4 J/cm(2)) or lambda830nm (34.5 mW; Ø; 0.

Laser light is capable of inducing proliferation of carcinoma cells in culture: a spectroscopic in vitro study.

Objective: The objective of this work was to evaluate the influence of time, treatment, and wavelength, through the assessment of the cellular viability with MTT, on the proliferation of H.Ep.2 cells subjected to laser irradiation or not (lambda685 and lambda830 nm) with the same energy density (4 J/cm2).
