Dentine hypersensitiveness treated by Nd∶YAG laser combined with enamel cement / 中国康复理论与实践

@#ObjectiveTo observe the effect of Nd∶YAG laser combined with enamel cement on dentine hypersensitiveness (DH).Methods120 DH cases (totally 182 teeth) were randomly divided into two groups. The experiment group (92 teeth) was treated with Nd∶YAG laser and enamel cement. The control group (90 teeth) was only treated with Nd∶YAG laser.ResultsEffective rates of the experiment group at the moment of treatment, 3 months and 6 months after treatment were 97.8%, 96.7% and 90.2 % respectively, and that of the control group were 95.6%, 91.1% and 84.4%. There was a significant difference between two groups (P<0.05).ConclusionNd∶YAG laser combined with enamel cement has an obvious effect on DH.
