Dental pulp capping materials: modulators of stem cell behavior and regenerative potential

Area of Science:

• Biomaterials Science
• Stem Cell Biology
• Regenerative Dentistry

Background:

• Pulp capping aims to preserve pulp vitality and avoid root canal therapy by promoting dentin bridge formation.
• Success depends on dental stem cell behavior and the chosen pulp capping material.
• Understanding material-stem cell interactions is vital for optimizing treatment outcomes.

Purpose of the Study:

• To review the effects of various pulp capping agents on dental-derived stem cells.
• To explore molecular pathways activated during pulp capping procedures.
• To assess the influence on stem cell differentiation, proliferation, and dentin bridge formation.

Main Methods:

• Comprehensive literature review.
• Evaluation of pulp capping materials' effects on dental-derived stem cells.
• Focus on molecular pathways regulating stem cell fate and reparative responses.

Main Results:

• Pulp capping materials have diverse effects on dental stem cells, based on their composition.
• Specific molecular pathways are activated, regulating stem cell differentiation and repair.
• Calcium hydroxide and MTA activate distinct pathways promoting odontogenic differentiation.

Conclusions:

• Material-stem cell interactions are crucial for successful pulp capping.
• Targeted therapies modulating molecular pathways can enhance pulp regeneration.
• Further research should refine materials and protocols for better stem cell responsiveness.
