Therapeutics of stem cells in periodontal regeneration

The structure and composition of the periodontium are affected in many acquired and heritable diseases, and the most significant among these is periodontal disease. Periodontal regeneration is considered to be organically promising but clinically capricious. The principal requirements for tissue engineering are the incorporation of appropriate numbers of responsive progenitor cells and the presence of bioactive levels of regulatory signals within an appropriate extracellular matrix or carrier construct. Stem cell therapy is a treatment that uses stem cells, or cells that come from stem cells, to replace or to repair a patient's cells or tissues that are damaged. And, recent progress in stem cell research and in tissue engineering promises novel prospects for tissue regeneration in dental practice in the future, with regeneration of a functional and living tooth as one of the most promising therapeutic strategies for the replacement of a diseased or damaged tooth.
