Abstract: (5672 Views)
The purpose of this study was to evaluate the effect of pulsed Nd:YAG laser on the dentin surface by scanning electron microscope (SEM) in order to determine the optimum time and power of radiation to seal the exposed dentinal tubules. Horizontal sections were taken from newly extracted impact third molar teeth. Smear layers from the dentin surfaces were removed by phosphoric acid and all samples were treated with the pulsed Nd:YAG laser in different powers and times. The results of this study showed that the laser pulsed Nd:YAG with power: 1.7 w during 60 seconds was able to seal the exposed dentinal tubules.
