Legends

Fig.1 G2 representative sample image at medium third. 810nm diode laser irradiation at 1,5 W in cw in sodium hypoclorite wet canal - 5sec three times: Noticeable smear layer still remained on the treated surface with areas of partial occluded dentinal tubules. Remarkable superficial thermal effect with signes of recristallization of dentin surface.

Fig.2 G2 representative sample image at apical third. 810nm diode laser irradiation at 1,5 W in cw in sodium hypoclorite wet canal - 5sec three times: Noticeable smear layer still remained on the treated surface with some areas of partial occluded dentinal tubules. Evidence of vaporization of the collagen matrix and absence of collagen fibers and residual sodium hypoclorite crystals.

Fig.3 G2 representative sample image at medium third. 810nm diode laser irradiation at 1,5 W in cw in sodium hypoclorite wet canal - 5sec three times: evidence of signes of laser irradiation with complete superficial vaporization of organic matrix; root canal surfaces exhibit open tubules, some residual debris and smear layer still present.
