Dr. Eneas studied Dentistry at the Federal University of Paraiba, Brazil, and graduated in 2009 and became specialist in Endodontics in 2011. He is currently finishing his Master’s degree in Endodontics too, at the School of Dentistry São Leopoldo Mandic, in Campinas, Brazil. He is Endodontic practitioner since 9 years ago with a lot of cases, with continuing education and joined at Baiano Federal Institute in 2018.


One of most relevant questions in Endodontics currently is the importance of irrigation. The current instrumentation protocols recommend an ever smaller number of instruments objectifying reduce the surgical time of root treatment. So, this fact results other question because reducing the treatment time, we reduce the permanence of solution into the root canal.  This is specially critical when we use sodium hypochlorite, since its solvent and antimicrobial properties are time-dependents. Also, the irrigants reduct friction between instrument and dentin and cools the file and tooth. The traditional method with needle and syringe has been shown incapable of reaching areas like isthmus. A lot of researches show that even using modern protocols of instrumentation, a considerable percentage of dentin walls in the root canal remain untouched by the liquid or the instruments. It is so critical. So, that’s why is important know and use protocols and techniques that potentialize the effects of sodium hypochlorite, mainly against bacterial biofilm, strongly adhered to the walls of root canal. Passive Ultrasonic Irrigation, EndoVac, Endo Activator, XP Endo Finish and Easy Clean are some of example of instruments and devices used for potentialize the properties of solution to eliminate microorganisms and dissolve vital and organic tissues that could be determinant for endodontic unsuccess. It is important to note, however, that as important as taking the irrigating substance to the full extent of the root canal is to do so with levels of safety not to take it to the periapical tissues. This is because most irrigating chemicals, especially sodium hypochlorite, have cytotoxic properties, which can trigger undesirable flare-ups. Therefore, this presentation has the objective to discuss the importance of a good irrigation of describing the most modern and safe techniques of potentiation of root canal irrigation.
