Effect of Different NanoScaffolds on Pulp Regeneration in Non-Vital Immature Permanent Teeth (Randomized Clinical Trial)

platelet rich fibrin is obtained by removing the middle layer from a centrifuged blood sample and is rich with platelets that plays an important role in tissue regeneration mesoporous silica nanoparticles are high surface area and excellent biocompatibility and enhance the outcome hyalurnic acid nanoparticles are high water capacity and involved in cell proliferation and adhesion and help in tissue regeneration pomegranate nanoparticles has anti-inflammatory and antibacterial effect and also help in tissue proliferation and regeneration
