Autologous Stem Cell Application in Periodontal Regeneration Technique (SAI-PRT) Using PDLSCs Directly From an Extracted Tooth···An Insight

Periodontal regeneration represents the ultimate goal of periodontal therapy. The current regenerative techniques have limited success rates especially in advanced periodontal defects. Currently the research is focused on novel cell-based approaches for periodontal regeneration to overcome the limitations of existing treatment. The human clinical trial on stem cells based periodontal regeneration is promising. The plethora of animal studies provide sound evidence to support the belief that periodontal ligament stem cells (PDLSCs) can be used for periodontal regeneration. The direct application of autologous periodontal stem cells in treatment of intrabony defects is attempted for the first time in periodontal literature. Stem cell Application in Periodontal Regeneration Technique (SAI-PRT) using direct PDLSCs has overcome the limitations and concerns of ex- vivo stem cell culture methods like high cost, technique sensitivity, loss of stemness during cell passage, genetic manipulation and tumorigenic potential. Clinical feasibility, success and cost effectiveness over currently available techniques are encouraging. The clinical utility of this novel idea is recommended.
