Abstract

Abstract: Objective: To determine the efficacy of bioactive glass air polishing on the dentine hypersensitivity. Methods: In the double-blind randomized control study, 11 subjects with periodontal diseases who need supragingival scaling and air polishing were enrolled. The left and right half mouth teeth were divided into test group (bioactive glass air polising) and control group (sodium hydrogen carbonate air polishing). A visual analogue scale (VAS) was used to evaluate the dentin hypersensitivity at baseline, 1 week, and 4 weeks. Results: At baseline, the test group and the control group VAS were 1.8±2.4 and 1.7±1.9. 1 week, the test group decreased to 1.0±1.3, the control group increased to 2.0±1.4 (P>0.05). The patients in test group (0.9±1.4) reported more comfortable experience than the control group (1.0±0.8), However, the difference was not significant (P>0.05). Conclusion: Bioactive glass air polishing showed a trend of reducing dentin hypersensitivity. The patients had more comfortable experience in the treatment.
