Dental-related tissue contains several types of stem cells collectively called dental stem cells (DSCs). In this stem cell family, there are 6 named members so far recognized and described. These include dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHED), periodontal ligament stem cells (PDLSCs), stem cells from apical papilla (SCAP) of developing tooth, dental follicle stem/progenitor cells (DFPCs) and gingival stem cells (GSCs). All these easily-accessible stem cells can be derived from dental tissue obtained from young and adult patients which is newfangled in the field of regenerative dentistry.
