A SHORT VIEW ON NANO HYDROXYAPATITE IN TOOTHPASTE PREPARATION

Nanotechnology is the ability to product, control and use matter in nanometer dimensions. The size of the particles is very important in nanotechnology, because in the nanoscale, the dimensions of the material are very effective in its properties and the physical and chemical properties of individual atoms and molecules are different from the properties of the mass of matter. Nano Hydroxyapatite has been widely used in jaw and facial surgeries due to its unique properties such as the ability to bond chemically with bone, not causing toxicity or inflammation and stimulating bone growth. Hydroxyapatite is a network of calcium that is found naturally in the network of teeth and bones. By covering the teeth and causing slippage in small cracks in response to the acid, this substance decomposes before the enamel of your teeth and protects the teeth against decay and cavities. Studies have shown that these crystals begin to restore the enamel material in less than ten minutes and perform the restoration and strengthening of teeth better than toothpaste containing fluoride. Due to the fact that the preparation of toothpaste using nanotechnology has a high cost and is not accessible to the public, in this research an affordable toothpaste that protects teeth from decay has been prepared using available materials. Hydroxyapatite can be a substitute for fluoride because fluoride eliminates bacteria, while hydroxyapatite prevents bacteria from sticking to teeth. Since, Hydroxyapatite is naturally present in our body, unlike fluoride, it is non-toxic and biocompatible, and it is not harmful for children and pregnant women.
