[Pulsed ND:YAG laser irradiation and 2% NaF treatment in caries-like lesion formation in enamel:an in vitro study]
The purpose of this in vitro study was to determine the combined effects of ND:YAG laser irradiation and 2% NaF on caries-like lesion formation in human enamel.There were four groups:(1)control;(2)Nd:YAG laser only;(3)2%NaF only;(4)Nd:YAG laser before 2% NaF.The result show the lesion body depths were significant differences between the control group and all treatment group,and between Nd:YAG laser before 2% NaF group and both Nd:YAG laser group and 2% NaF group(P<0.05).The surface zone depths between Nd:YAG laser before 2% NaF group and both 2% NaF group and both 2% NaF group and control group were also significantly different(P<0.05).
