Abstract

Objectives: To evaluate the preliminary outcomes of using varnish patients with  dentin  hypersensitivity.  Methods:  A  clinical  interventional, uncontrolled study was conducted on 89 patients with a total of 158 hypersensitive teeth at the Department of Odonto-Stomatology, Military Hospital 103, from June 2024 to February 2025. All patients received treatment with varnish fluoride. Treatment outcomes were assessed using the Yeaple probe and the Visual Analog Scale (VAS) at three time points: 30 minutes, 1 month, and 3 months post-treatment. Results: Among the 89 patients, 23.6% were male, and 76.4% were female. The highest rate of dentin hypersensitivity was observed in the 35 to < 50 age group (46.1%). The most common etiology of hypersensitivity was cervical tooth wear (41.6%). A significant improvement in hypersensitivity was observed following treatment (p < 0.05). According to the Yeaple probe, the treatment efficacy at 30 minutes, 1 month, and 3 months was 60.81 ± 43.93%, 62.25 ± 30.73%, and 73.90 ± 25.75%, respectively. VAS scores also showed a corresponding reduction in sensitivity: 11.66 ± 2.33mm, 19.16 ± 3.47mm, and 24.41 ± 4.56mm (p < 0.05). Conclusion: Varnish fluoride demonstrated significant efficacy in reducing dentin hypersensitivity, particularly after 3 months of treatment. However, as this is only a preliminary study, further clinical comparisons with other treatment modalities are recommended.
