【Abstract】 To evaluate the clinical effects of the self-made No.1 desensitizer on the treatment of dentin hypersensitivity. Methods:The experimental groups including 181 patients were treated with self-made No.1 desensitizer in 362 teeth;75% sodium fluoride pastes were used in 99 cases,198 teeth as the control group.The clinical effects were observed in the following 1 month to 3 years.The histological changes on the surface of extracted teeth induced by the medical effects were observed under SEM.Results:The successful rate of the experimental group was 95.6% while the control group was 61.1%.It reduced the hypersensitivity by obstructing the dentinal canaliculi.The results indicated that the self-made No. 1 desensitizer was safe to the oral cavity,no irritation of damage to oral mucosa.Conclusion:The clinical effect of self-made No. 1 desensitizer is much better than that of sodium fluoride.更多还原
