Tissue engineering in periodontics is now well within reach. It is the complex interplay of cells such as osteoblasts, cementoblasts and fibroblasts, scaffolds - collagen, hydroxyapatite, synthetic material etc interwoven with the action of mediators such as growth factors, differentiation factors and adhesion molecules, in appropriate sequence and quantities that result in successful tissue generation. The future holds many a promise, with the rapidly expanding fields of stem cell research and tissue engineering converging to form the new discipline of regenerative medicine, the aim of which...
