Root Canal Disinfection Challenges & Solutions

Root Canal Disinfection Challenges & Solutions

Learning Objectives:

• Describe the challenges facing the operator during root canal disinfection.
• State the ideal requirements of root canal irrigants.
• Discuss the uses, advantages, disadvantages of different root canal irrigants.
• Describe different techniques for delivery and activation of root canal irrigants.
• Identify the role of different intracanal medicaments in endodontics.

Abstract:

Chemical disinfection of the root can system is now the gold standard of modern endodontic therapy. Even though we have new and sophisticated file systems in the market, the key to endodontic success is based on chemical disinfection. In this presentation I am going to review the properties, advantages, disadvantages of the most commonly used root canal irrigants and intracanal medications used for root canal disinfection.

Introduction:

 Mechanical debridement of the root canal system is done with the use of either hand instruments or rotary nickel-titanium instruments which helps in removal of vital and necrotic remnants of pulp tissue, microorganisms, and microbial toxins.

The root canal system has been found to be very complex with anastomoses, cul-de-sacs, and deltas which are difficult if not impossible to clean completely. This region may accumulate necrotic tissues, microorganisms, and their by-products resulting in persistent periradicular inflammation, Therefore, root canal irrigation by using various chemical agents and inter appointment medications is an essential part of debridement as it allows for cleaning more than what might be achieved by root canal instrumentation alone.
