Hydroxyapetite Nanoparticles and Tricalcium Phosphate Nanoparticles Loaded on Platelet Rich Fibrin Membranes for Treatment of Gingival Recession

The "Glossary of the American of Periodontology" defines gingival recession (GR) as the apical movement of the gingival margin beyond the cement-enamel junction. Therefore, root surface exposure brought on by gingival recession results in cosmetic impairment, fear of tooth loss, increased susceptibility to root caries, and dentin hypersensitivity. The use of free gingival grafts, sliding pedicle grafts, subepithelial connective tissue grafts, envelope or tunnelling techniques, the use of acellular dermal, connective tissue allografts, guided tissue regeneration, and coronally advanced flap (CAF) are the surgical methods that have been developed to treat gingival recession. The medical area has been invaded by nanotechnology, and the findings are highly promising. Nanomaterials perform far better than conventional materials thanks to their superior surface, size, and quantum effects. Hydroxyapatites (HAs) are a family of materials used for bone grafting that have a high level of biocompatibility, which is partly due to their inclusion in naturally calcified tissue. The aim of the present study was to compare between nanocrystalline hydroxyapatite and tricalcium phosphate carried on PRP membrane in treatment of Miller's class 1 gingival recession in human.
