摘　　要：The canal walls of extracted human teeth, following Nd∶YAG Laser irradiation, were examined with a scanning electron microscope and compared with those prepared with conventional methods or pretreated with citric acid as control. The results showed that all the dentinal tubules were closed and smeared layer disrupted following laser irradiation, It was suggested that Nd∶YAG Laser irradiation would be expectablly applied to endodontics, especially in root canal therapy (RCT).The canal walls of extracted human teeth, following Nd∶YAG Laser irradiation, were examined with a scanning electron microscope and compared with those prepared with conventional methods or pretreated with citric acid as control.
