Đánh giá hiệu quả điều trị nhạy cảm ngà bằng varnish fluoride

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 2nd February 2023 to 4th 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.
