Contemporary Microbial and Antimicrobial Considerations in Regenerative Endodontic Therapy

Area of Science:

• Endodontics
• Regenerative Medicine
• Microbiology

Background:

• Regenerative endodontic therapy (RET) is increasingly used, but outcomes are unpredictable.
• Bacterial persistence in root canals hinders healing and root maturation in RET cases.
• The complex oral microflora and biofilm maturation in immature teeth with necrotic pulp remain understudied.

Purpose of the Study:

• To discuss biological and clinical challenges in RET.
• To review contemporary microbial community analysis for clinical data.
• To explore effective root canal disinfection methods compatible with stem cells and dentin integrity.

Main Methods:

• Review of current literature on RET challenges.
• Analysis of microbial community assessment techniques.
• Evaluation of disinfection strategies for regenerative endodontics.

Main Results:

• Bacterial persistence is a major obstacle in RET.
• Advanced microbial analysis can yield clinically relevant data.
• Disinfection protocols must balance efficacy with preservation of stem cells and dentin.

Conclusions:

• Addressing microbial challenges is crucial for predictable RET outcomes.
• Further research is needed for optimized, customizable RET approaches.
• Technological advancements offer promise for future RET innovations.
