[Experimental study on seal treatment of early root-surface caries in senile patients after irradiated by Nd:YAG laser].
OBJECTIVE
To study the curative effect of pulsed Nd:YAG laser on early root-surface caries in senile patients.


METHODS
Teeth with early root-surface caries removed from patients aged over 60 were irradiated with different energy output and sealant and observed under scanning electron microscope.


RESULTS
Surface layer on early root-face caries were seen to be honeycomb or nibbled before irradiation, melted after irradiated by Nd:YAG laser,and with a smooth surface of the lesion after sealed.


CONCLUSIONS
Early root-surface caries sealed with light-cured sealant after pulsed Nd:YAG laser irradiation is a safe and effective therapy.
