Mini review on the synthesis of porous hydroxyapatite nanomaterials for dental tissue engineering

Hydroxyapatite is a ceramic material composed of calcium phosphate, the most abundant mineral in human bone and teeth. Its physical and chemical properties allow its applications in bone tissue engineering, particularly in dental tissue engineering. Nanostructured hydroxyapatite is not widely used for biomedical applications yet, but it is now of great interest to the scientific community. This work summarises different ways for the synthesis of hydroxyapatite nanostructures having versatile morphologies, with an emphasis on wet chemical methods, and shows the possible applications of hydroxyapatite in dental applications and dental tissue engineering.
