The importance of natural resources in human general and dental health
Dental erosion can be defined as a localized chemical dissolution of tooth surfaces without bacterial involvement. As enamel lacks an inherent ability to restore itself if it is affected by fracture, abrasion or dental caries, hence the reconstruction of initial, superficial layer of enamel is governed by the saliva composition along with utilization of tooth pastes, mouth washes and other products having elements, for instance; calcium or fluoride as in eggshell and fluoride products. 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. Chicken eggshells have nowadays many applications; for example as a dietary calcium supplement, Bone substitute, also to assist in healing of damaged tissues, besides; as a natural source for calcium oxide, calcium hydroxide and calcium carbonate, moreover; in synthesis of experimental dental materials and artificial hydroxyapatite. Aim of this study was to 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 water.
