Abstract Aim: to assess the clinical effectiveness of Giomer varnish in comparison to sodium fluoride in reducing dentin hypersensitivity. Methodology: Using a Split mouth design, 66 participants (132 teeth) of the outpatient clinic in the Faculty of dentistry, Cairo University, were enrolled. Each participant should have at least two sensitive teeth in different sides of the same jaw, with a visual analogue scale score two or more.Teeth were examined by using different stimuli: Evaporative, thermal and tactile stimuli. Sides were categorized randomly into two groups according to the desensitizing agents used either sodium fluoride or Giomer varnish.Degree of Hypersensitivity was assessed by visual analogue scale (VAS) before the application of the agents T1, immediately after T2, 1 week T3 and one month later T4. Data were analyzed using Two way ANOVA, partial eta-squared, Kruskal-Wallis, Bonferroni-corrected Wilcoxon, Mann-Whitney test and Chi-square tests. Absolute risk, relative risk, relative risk reduction with 95% confidence interval of dentin hypersensitivity were calculated. vii Results: Sodium fluoride exhibited high VAS scale at T1 3.39(1.11), T2 3.21(0.99) and T4 3.13(1.01) with a non-statistical difference between them. While at T3 statistically lower VAS scale 1.30 (0.9) was shown in this group. Giomer exhibited high VAS scale at T1 3.79(1.5) followed by T2 2.17(0.57) and T4 2.56(1.87) with a non-statistical difference between them. While at T3 lower VAS scale 0.17(0.57) was shown in this group. Influence of different assessment times within each agent was statistically significant at P <0.0001. At T2 and T3, Giomer revealed statistically lower VAS scale and it exhibited a relative risk reduction by 83% at T3 and 24% at T4 |
