Recent advances in Endodontic irrigation

This book provides a comprehensive overview of root canal irrigation, highlighting its critical role in successful endodontic therapy. It traces the historical evolution of irrigants from the 19th century to modern practice, emphasizing the shift from empirical methods to evidence-based protocols. The text outlines the ideal properties of irrigants-such as antimicrobial action, tissue dissolution, smear layer removal, and biocompatibility-while acknowledging that no single solution fulfills all requirements. Detailed discussions cover commonly used agents like sodium hypochlorite, chlorhexidine, and newer formulations such as MTAD and Tetraclean, along with their mechanisms, advantages, and limitations. The book also explores recent advances, including combination irrigants, natural alternatives, and innovative delivery systems like ultrasonic and negative pressure irrigation. Ultimately, it concludes that effective root canal disinfection relies on a judicious combination of irrigants and modern techniques, ensuring both microbial control and preservation of periapical tissue health.
