This review details root canal irrigation, recommending sodium hypochlorite for its antimicrobial and tissue-dissolving properties. Chelating agents are advised to manage the smear layer, optimizing root canal treatment outcomes.

Area of Science:

  • Endodontics
  • Microbiology
  • Biomaterials

Background:

  • Root canal treatment aims to eliminate intraradicular infection by debriding the diseased pulp space.
  • The pulpal microenvironment presents unique challenges for effective disinfection and tissue removal.
  • Understanding these challenges is crucial for selecting appropriate irrigating solutions.

Purpose of the Study:

  • To review the pulpal microenvironment and irrigant requirements for root canal therapy.
  • To evaluate the efficacy and safety of sodium hypochlorite and chelating agents.
  • To propose an optimized clinical irrigating regimen.

Main Methods:

  • Literature review focusing on the properties of irrigating solutions.
  • Analysis of antimicrobial spectra and tissue dissolution capacities.

  • Assessment of chemical and toxicological profiles of irrigants.

    • Main Results:

    • Sodium hypochlorite is recommended as a primary irrigant due to its broad-spectrum antimicrobial activity and necrotic tissue dissolution.
    • Chelating solutions are effective adjuncts for smear layer prevention and removal.
    • Strategies to enhance efficacy while minimizing toxicity are discussed.

    Conclusions:

    • An effective clinical irrigating regimen involves the combined use of sodium hypochlorite and chelating agents.
    • Optimizing irrigant use is key to successful root canal treatment and infection prevention.
    • Current trends in root canal irrigation are critically examined.
