Abstract

Aim: to assess the clinical effectiveness of Giomer varnish in comparison to sodium fluoride in reducing hypersensitivity.
Methodology: Using a Split mouth design, 66 participants 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. Degree of Hypersensitivity was assessed by visual analogue scale (VAS) before the application of the agents , immediately after , 1 week and one month later . 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.
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. 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.
Conclusion: Giomer varnish is a promising desensitizing agent, which can replace sodium fluoride varnish in management of hypersensitivity.
