The greatest challenge to successful endodontic treatment is the elimination of microbiota. Mechanical instrumentation as well as auxiliary chemical substances are used to eliminate this microbiota. In addition to irrigating solutions, other complementary techniques such as passive ultrasonic irrigation (PUI) and laser are used to optimize elimination of microorganisms. Thus, the present study aimed at a bibliographic survey of different types of agitation of irrigating solutions in endodontic treatment. PUI has been suggested as a mean to improve canal debridement. Laser has been used for presenting therapeutic advantages to treatment. All techniques considered to better clean root canals showed some improvement. The most commonly used technique is ultrasonic agitation due to being an efficient and practical procedure. It could be concluded that efficiency of microbial decrease is better achieved when a higher concentration of irrigating solution is used, irrespective of the chosen final agitation.
