[Clinical observation of semiconductor laster for treatment of hypersensitivity of the dentine]
OBJECTIVE: Observation of clinical results and SEM features in treatment of hypersensitive dentine by semiconductor laser.METHODS:Semiconductor laser was compared with conventional NaF method for the treatment of 100 teeth with typical hypersensitive dentine which were divided into two groups.RESULTS:The efficiency of the laser group was 96%,while that of NaF group was 76%.The laser irradiation could decrease hypersensitive dentive. There was marked difference between two groups.It was testified by SEM that the dentinal tubule was sealed by semiconductor laser irradiation.CONCLUSION:The safe,effective and easy methods was provided for treating the hypersentitive dentive by use of semiconductor laser.
