Abstract

Objective: To evaluate the effectiveness of dentin hypersensitivity treatment with varnish fluoride on a group of students. Subjects and methods: Study on 96 patients with 183 teeth diagnosed with DH and treated with varnish fluoride on study subjects who were students from the 2^nd February 2023 to 4^th June 2023 years at the Ha Noi Univercity of Business and Technology who visited the Odonto-stomatology department. Evaluate the effectiveness of treatment for dentin sensitivity according to Yeaple score and VAS scale after 30 minutes, 1 month, 3 months of treatment. Results: Sensitivity according to the Yeaple scale at the time after treatment compared to before treatment significantly improved sensitivity (p<0.05). After treatment, at the following time points, there was an improvement compared to the previous time, reflected in the effectiveness index at the time of 30 minutes, 1 month, and 3 months of treatment, which was 69.01 ± 41.09%; 76.63 ± 44.17% and 84.03 ± 46.52%. The level of sensitivity according to the VAS scale at the time of 30 minutes, 1 month, and 3 months after treatment was 11.87 ± 7.90mm higher than before treatment, respectively; 20.66 ± 9.27mm and 29.53 ± 8.54mm (p<0.05). After 3 months of treatment, there was a marked improvement in both the scale value and the clinical effect; the average efficiency index was 83.29 ± 9.93%. Conclusion: Treatment of dentin hypersensitivity with varnish fluoride showed a significant effect, especially after 3 months of treatment.
