Pulp Innate Immune Defense: Translational Opportunities

Area of Science:

• Endodontics
• Regenerative Medicine
• Immunology
• Dental Pulp Biology

Background:

• Successful regenerative endodontic procedures depend on understanding dental tissue behavior in health, disease, and repair.
• Collaboration between clinicians and basic scientists is crucial for advancing regenerative endodontics and improving patient outcomes.

Purpose of the Study:

• To review dentin-pulp biology.
• To explore the interplay between infection, inflammation, and regeneration in the dental pulp.
• To identify potential therapeutic targets for enhancing regenerative endodontic procedures.

Main Methods:

• Literature review focusing on dentin-pulp biology.
• Analysis of the role of neutrophil extracellular traps (NETs) in pulp inflammation and regeneration.
• Discussion of potential clinical applications based on current biological understanding.

Main Results:

• Neutrophil extracellular traps (NETs) in the pulp have a dual role: they attempt to control bacterial infection but can also increase cell death and chronic inflammation.
• Abnormal NET levels may result from immune system dysfunction, viral infections, or bacterial factors hindering clearance.
• A pro-inflammatory connection is proposed between NETs and the inflammasome, activated by pathogen- and damage-associated molecular patterns in the pulp.

Conclusions:

• Continued research partnerships between scientists and clinicians are vital for advancing regenerative endodontics.
• A deeper understanding of the inflammation-regeneration relationship in the dentin-pulp complex will benefit patients.
• Future clinical strategies may involve NET inhibitors, inflammasome modulators, phototherapies, and epigenetic approaches.
