Introduction: Preparation and disinfection of the root canal aims to remove organic and inorganic tissue from within the root canal, reduce the number of microorganisms, neutralize endotoxins inside the dentin, and prepare the root canal for proper obturation. These aims can be achieved in many cases to a degree that promises a high chance of success through a combination of mechanical preparation and chemical disinfection.
Results and Conclusions: Preparation and disinfection both physically and chemically act on the lumen of the root canal itself, trying to remove as much infected material as possible, but also act on the surrounding dentin and all of its components including the dentinal tubules.
