    Background: Chicken eggshell mainly comprises of calcium and phosphorous along with other minerals as trace elements, so it has been considered as a natural source of calcium for enamel remineralization. Aim of the study: Test and compare the efficacy of two various application intervals of chicken eggshell powder (CESP) solution on the microhardness of artificial erosion like lesion of enamel, compared with sodium fluoride and de-ionized. Materials and Methods: twenty sound permanent upper first premolars were used. Samples were distributed randomly as three study and one control groups, each one comprised of five teeth. Then all samples were subjected to demineralization by soft cola drink. The study groups are: Group A: untreated (demineralization followed by immersion in deionized water ,as control), Group B : ..
