Stem cells in dentistry--Part II: Clinical applications

Area of Science:

• Regenerative Dentistry
• Biomaterials Science
• Immunology

Background:

• Alveolar ridge augmentation is crucial for dental implants, driving demand for advanced regenerative techniques.
• Stem-cell-based therapies, particularly using Mesenchymal Stem/Stromal Cells (MSCs), are emerging as a leading approach for bone regeneration.
• Understanding the interaction between donor MSCs and the recipient's immune system is vital for treatment success.

Purpose of the Study:

• To review advancements in regenerative dentistry focusing on stem cell technology.
• To highlight current stem cell-based alveolar bone regenerative therapies.
• To discuss factors influencing stem cell-mediated bone regeneration, including immune responses.

Main Methods:

• Literature review of stem cell applications in regenerative dentistry.
• Analysis of pre-clinical studies on tooth and oral organ regeneration.
• Discussion of immunomodulatory roles of MSCs in bone regeneration.

Main Results:

• Autologous MSCs are the current standard for stem cell-based alveolar bone regeneration.
• The interplay between donor cells and recipient immunity significantly impacts regenerative outcomes.
• Emerging applications include MSC-based immunotherapy and dental stem cell banking.

Conclusions:

• Stem cell technology, especially MSCs, offers significant potential for esthetic and functional reconstruction in prosthodontics.
• Further research into the immunomodulatory aspects of MSCs is essential for optimizing dental regenerative therapies.
• Future directions involve clinical translation, immunotherapy, and commercialization through dental stem cell banks.
