The irrigation of the root canal performs a very important role in endodontic treatment, it acts precisely on the cleaning and disinfection of the canal, eliminating necrotic remains, dentin debris, microorganisms and their disposal. Sodium hypochlorite (NaOCl) is considered to be the prime (SCR) irrigant because of its tissue dissolution and antimicrobial properties. There are areas in the canal that are anatomically complex, difficult to endodontic instruments access, such as, isthmus, and root apex. These hard to reach areas are difficult to clean, and when not reached can lead to endodontic failure. In order to prevent endodontic treatment failure, the penetration of the irrigant is crucial in all the areas of the root canal, especially in areas inaccessible to endodontic instruments. This study performs review of the various endodontic activation systems. It was observed that to optimize the properties of irrigants and to supplement their limitations there are several types of irrigation activation techniques, which can be divided into two categories: manual irrigation techniques and machine-assisted irrigation techniques. Manual irrigation techniques include: positive pressure through a syringe being able to be equipped with a variety of needles, manual dynamic agitation using gutta-percha cones and brushes. Machine-assisted irrigation techniques include: sonic and ultrasonic techniques, negative pressure, rotary brushes, and continuous irrigation during rotary instrumentation. With this literature review we could conclude that no research demonstrates the total efficiency of irrigation systems. It is crucial to know the various systems adjusting with individual competence and knowledge, consequently allowing a higher success rate in endodontic treatments
