It is a disease that can be preventedand if diagnosed in early-stage tooth decay can be stopped by applying various preventive materials. Theprimary prevention of dental caries mainly focused on young children. Fluoride has been widely used as apreventive measure against caries development. Fluoride is found in topical and systemic form, the topicalform is good, has a high life span. Recent advancements suggest that asymptomatic regimen of caries lesionhas the inherent of re-mineralization. In the field of dentistry, nanotechnology has been introduced which hasdeveloped substances ranging from 100nm or smaller in size. Nanotechnology replicates the natural dentalenamel by the process of bio-mineralization. Leading an integral part of bone and teeth is the hydroxyapatite.Since, nano-hydroxyapatite can provide preventive and therapeutic loom to caries in children worldwide,therefore various researches are performed to improve its capacity in clinics.]]>
