Abstract:
In order to study the effect of pulse Nd:YAG laser on hypersensitive dentin and inner wall of root canal.The morphologi- cal changes were observed with a SEM.The results showed that the low power with high energy density.Laser irradiation did not do harm to normal teeth tissue.The melted layer of dentin matrix extended to dentinal tubles,and the dentinal tubles were sealed to a depth of 15 um.The conventional preparation of root canal with laser irradiation provided much advantage in clearing the stained layer of inner wall in comparison with conwentional preparation of root canal alone.
