Dentine hypersensitivity often occurs in patients with conditions of periodontal disease, for example with different stages of generalized periodontitis. Although today there is a wide variety of treatments for dentine hypersensitivity, unfortunately there is still a need to optimize existing treatments in order to obtain long-term results in reducing dentine hypersensitivity. The purpose of this study was to evaluate the effectiveness of treatment of dentine hypersensitivity in patients with generalized chronic periodontitis by the proposed method of treatment using low-level laser therapy and bee products. Material and methods. The study included 104 patients with generalized periodontitis and dentine hypersensitivity. Patients were divided into 4 groups according to the received method of treatment. we used indices of intensity and prevalence of dentine hypersensitivity to assess the severity of dentine hypersensitivity. In the first group, varnish based on sodium fluoride was used for the treatment of dentine hypersensitivity, in the second it was ethanolic extract of propolis, in the third group we used low-level laser therapy (810 nm). In the fourth group, treatment was performed using a combined usage of ethanolic extract of propolis and low-level laser therapy (810 nm). The values of the obtained indices of intensity and prevalence of dentine hypersensitivity were evaluated before treatment, immediately after treatment, one week, 1 month, 3 months, 6 months and one year after treatment in each group. Statistical significance of the results was evaluated in IBM SPSS Statistics, V. 25.0 (Armonk, NY: IBM Corp.). Results and discussion. The mean values of indices of intensity and prevalence of dentine hypersensitivity did not differ significantly before treatment in all four groups. In each group, treatment was effective immediately after receiving it, as evidenced by a significant decrease in the average values of the indices. The mean values of indices of intensity and prevalence of dentine hypersensitivity did not return to the values obtained before treatment, but the lowest values were obtained in the fourth group. The results of comparisons between groups are statically significant (p <0.05). Conclusion. The analysis of the obtained results of the indices of evaluation of the effectiveness of the proposed method of treatment of dentine hypersensitivity indicates a high clinical stability of the obtained effect and its prolonged effect.
