Key elements of dental tissue engineering
• Cell attachment & migration
• Permit delivery of growth factors
• Enable influx of oxygen
• Porosity is critical
• Degradation is fundamental
• Should not be toxic
• Ceramics, natural or synthetic
Application of dental stem cells
Dental Pulp SC -Generate bone, dentin complex
-Repair damaged dental tissues
-Induce bone regeneration
Periodontal ligament SC
-Form cementum & alveolar bone
-Cures periodontal lesions in pig
Dental follicle SC -Forms cementum in vivo
SC from apical papilla -Osteoblasts & odondoblasts
-Regenerative endodontic therapy
Advantage of dental stem cells
• New promising therapeutic approach
• Great potential for discovering new treatments & cure
• Can regenerate a damaged tooth
• Differentiate -connective, neural, muscle, bone & dental
• Repair bone damaged by disease or trauma
More research required
