Abstract
|
|
|
|
An ideal irrigant should have fulfill several abilities to lubricate root canal spaces, dissolve organic and inorganic remnants, kill planktonic and biofilm microbes. Concurrently, it should have non-toxic to periapical tissue and non-allergenic characteristics. There have been many efforts to develop the better irrigants, however, there is not an ideal irrigant until now. Sodium hypochlorite (NaOCl) have been used as main irrigants for root canal treatment for a long time. Additionally, ethylenediaminetetraacetic acid (EDTA) can be used for removal of inorganic remnants like smear layer and chlorhexidine digluconate (CHX) for getting better antimicrobial effect. Irrigation is essential and important part for successful root canal treatment. For the anatomical structures like fin and isthmus, and un-cleaned area by mechanical instrumentation, chemical irrigation can be the only way to clean those area. We always have to make an effort to do irrigation on all of intracanal area thoroughly. This article is focused on NaOCl, and aimed to know the mechanism of action, find the methods for increasing the efficacy, and interaction with other irrigants for cautious application.
