SP-14 Pulp Regeneration: Challenges in Microbial Control

4.5 (2 votes)

CE Credits: 1.5

Course Description:   The regeneration of the pulp-dentin complex requires high-level disinfection of the root canal system prior to the application of tissue engineering principles. Indeed, previous work showed that the presence of microorganisms in the root canal system altered the patient’s innate regenerative capacity, resulting in ectopic tissue formation or a failure in regeneration. Current disinfection methods rely heavily on conventional antimicrobial irrigants and intracanal medicaments, including antibiotics and calcium hydroxide. However, there is palpable uncertainty about the efficacy of traditional microbial control for pulp regeneration. New disinfection tools, such as antibacterial nanoparticles and photoactivated disinfection, have been developed and investigated to overcome the limitations of traditional methods. This lecture will provide the current knowledge of antimicrobial treatment for pulp regeneration and its limitations as well as new antimicrobial therapies for enhanced disinfection. Additionally, the potential use of new disinfection methods in clinical regenerative endodontic treatment will be discussed for practitioners.  

At the conclusion, participants should be able to:

  • Recognize the importance of high-level disinfection in regeneration of the pulp-dentin complex.
  • Describe current antimicrobial protocols and their limitations in clinical regenerative endodontic treatment.
  • Discuss the new antimicrobial therapies for pulp regeneration.
