The purpose of this review is to assess the efficacy of different irrigating solutions in the removal of the smear layer from the ischolar_main canal. Irrigating solutions are used in ischolar_main canal treatment for the removal of the infected tissue which may still be present especially in the accessory canals. There are other uses for irrigating solutions like anti microbial property and lubrication .The removal of smear layer is vital for the adaptation of the obturation material to the ischolar_main canal walls and the prevention of reinfection as some micro organisms penetrate deeper into the dentinal tubules. The most commonly used irrigating solution in day to day use are sodium hypochlorite and chlorhexidine gluconate which are said to have very good anti microbial efficacy but inefficiency in the removal of smear layer. This review focuses on the establishment of irrigants in the removal of smear layer and its use in routine procedures.
