THE ROLE OF HYDROXYAPATITE EXTRACT AS A BIOACTIVE INGREDIENT IN DENTISTRY

Hydroxyapatite (Ca10(PO4)6(OH)2) is an inorganic mineral this material can be made from synthetic chemicals or natural biomaterials such as egg shells, fish scales, gypsum, and bone. Calcium contained in bone is 7.07% CaCO3, 1.96% CaF2, and 58.30% Ca3(po4)2. Hydroxyapatite is highly biocompatible and well tolerated by human oral tissues. Hydroxyapatite has osteoconductive properties, stimulating osteoblast development and bone production. The advantages of this biomaterial can be used in dentistry such as bone tissue reconstruction, soft tissue engineering, dental implant coatings, treatment of periodontal effects, and restorative materials such as composite resins and GIC. Purpose: Knowing about the application of hydroxyapatite extract as a bioactive ingredient in dentistry. Method: The design of this paper is a literature review. Conclusion: Currently the use of hydroxyapatite extract has been widely used in all fields of dentistry because hydroxyapatite has many advantages, one of which is its bioactive properties and biocompatibility.
