Background: Eggshells are the rich sources of minerals since it contains calcium, phosphorous, magnesium, strontium and fluoride. Hence, it can be used as remineralizing agent.

Aim and Objectives: To evaluate the effect of Chicken eggshell paste on surface microhardness of bleached enamel surface in comparison with commercial CPP-ACP paste using Vickers microhardness test.

Materials and Methodology: 96 extracted permanent anterior teeth were decoronated at CEJ and embedded into self-cure acrylic with the labial enamel surface exposed. All samples were randomly divided into the following groups: Group A: No bleaching was done for samples. Group B: Bleaching was done by using 35% Hydrogen peroxide. Group C: Bleaching was done with 35% Hydrogen peroxide followed by application of CPP-ACP. Group D: Bleaching was done with 35% Hydrogen peroxide followed by application of Chicken Eggshell paste. All the samples including those of Group A were stored in artificial saliva at 37°C. The baseline surface microhardness was measured, followed by surface microhardness measurement of posttreatment done at the end of 2 weeks. Data was analyzed using Kruskal Wallis test and Wilcoxon Signed Rank test.

Results: Statistically significant differences were observed between the group B followed by bleaching which decreased microhardnesss values. There were no significant differences between both remineralizing agents used i.e. eggshell paste and CPP-ACP.

Conclusion: Chicken eggshell paste can be used as an alternate to commercially available remineralizing agents.
