Objective To observe and compare the therapeutic effects of Hybrid coat and Gluma desensitizer in treatment of dentine hypersensitivity of posterior teeth occlusal surface. Methods One hundred and twenty teeth from 60 patients with dentine hypersensitivity randomly received Hybrid coat desensitive treatment (Hybrid coat group, n=60) or Gluma desensitizer desensitive treatment (Gluma group, n=60). Air conditioning stimulation and stimulation probing method were used to detect and record the sensitive condition of teeth before treatment, immediately after treatment, 1 month after treatment and 3 months after treatment, and the desensitization valid rates were calculated and compared between groups. Results The desensitization valid rates of Hybrid coat group immediately after treatment, 1 month after treatment and 3 months after treatment were 91.7%, 90.0% and 81.7% respectively, and those of Gluma group were 88.3%, 75.0% and 65.0% respectively. Statistical analysis indicated that there was no significant difference in the desensitization valid rates between two groups immediately after treatment (P>0.05), while the desensitization valid rates of Hybrid coat group 1 month after treatment and 3 months after treatment were significantly higher than those of Gluma group (P<0.05). Conclusion Both desensitizers have favorable immediate therapeutic effects on dentine hypersensitivity. The mid-term therapeutic effect of Hybrid coat is better than that of Gluma desensitizer, while the long-term effect leaves room for further investigations.
