The successful endodontic treatment always has strong back bone of thorough irrigation of root canal system. It is absolutely clear that a three-dimensional cleaning shall pave the way for three dimensional obturation of the root canal system. Of all the irrigants which have been used in endodontics, the role of sodium hypochlorite holds paramount importance. Various percentages of this magical solution have been advocated by researchers all across the globe, but the use of 5.25% remains popular. Different techniques of irrigation also have a detailed mention in the literature and the use depends on the individual’s preference. Whatever percentage or technique is used, thoroughness is the key behind the success. This article presents case reports of few such successful cases of Endodontics, where irrigation had a major role to play.
