Irrigation and disinfection of the root canal

This lecture will discuss what we need to do to get adequate disinfection of the root canal system with subsequent healing of periapical lesions. The most important aspect in this context is neither new tools nor special disinfectants, but a thorough understanding of the actual case we are treating. It will be shown that not all endodontic cases are equal, and how we can address the more difficult cases by choosing our approach wisely. One core issue is timing. How much time are we prepared to spend on a case, and what is best for our patient? In this context, the effectiveness and compatibility of the means we use to debride and disinfect are key. The other core issue is anatomy. Whilst many clinicians are aware of the macro anatomy of root canal systems, fewer consider micro anatomy.

Learning objectives:

• Appreciate the importance of diagnostics and anatomy in current and future treatment concepts.
• Understanding the efficacy versus the effectiveness of different protocols under different conditions.
• Knowing the core characteristics and interactions of the main chemical agents used in root canal cleansing.
