The main aim of the root canal treatment is to disinfect the entire root canal system. This can be achieved by mechanical instrumentation and chemical irrigation, with medication of the root canal. Microorganism and their byproducts are the major cause of pulpal and periodical pathos is. To reduce or eliminate bacteria and pulp tissue remnants, various irrigation solutions have been suggested to be used during treatment. Sodium hypochlorite (NaOCl), a reducing agent, is a clear, straw-colored solution containing about 5% of available chlorine. It is the most widely used irrigating solution. NaOCL is an excellent nonspecific proteolytic and antimicrobial agent, most common irrigant during root canal therapy. New equipment introduced into root canal irrigation includes the EndoActivator , Vibringe, and various ultrasonic devices where the irrigant is directed into the canal through the vibrating tip.It is indicated that these devices may facilitate irrigation, particularly in the difficult to reach areas of the canals, such as fins and isthmuses and in large lateral canals. With this background, the main aim of the study is to review the method and modification to improve the efficacy of sodium hypochlorite as root canal irrigant and thereby prevent the failure of root canal treatment.
