Introduction: Use of fluoride compounds is one of the most effective ways of preventing decay and among these varnishes have high acceptance among different fluoride products.

Aim: Hence, the aim of this research was to evaluate the micro-hardness of tooth enamel after the usage of two different commercial products of fluoride varnish.

Materials and Methods: This in vitro experimental study was performed on 51 extracted premolar teeth. The teeth were divided randomly into three 17-membered groups. The first group received Duraflor varnish, the second group received Ariadent Iranian varnish while the third group received no treatment. Micro hardness of tooth enamel was measured utilizing Vickers method before and after the use of fluoride varnish. ANOVA, Tukey, and Wilcoxon statistical tests were utilized for statistical analysis of data.

Results: The comparison of mean change in micro hardness before and after the use of fluoride showed that increase in micro hardness in Duraflor varnish and Ariadent varnish group was significant when compared to control group (p<0.05) but no significant statistical difference was observed in terms of mean of micro hardness after intervention between two groups of Duraflor varnish and Ariadent varnish (p>0.05).

Conclusion: According to the findings, the use of fluoride significantly increased the enamel micro hardness which did not show a significant difference between two groups of Duraflor varnish and Ariadent varnish.
