Root Canal Irrigants in Pediatric Dentistry – A Narrative Review

Abstract

The two main techniques used in endodontic therapy to get rid of all the germs, dead tissue, and microbial by-products from the canal are chemical and mechanical root canal debridement. Surface disinfection is a great use for sodium hypochlorite, a potent organic tissue dissolver with a wide range of antibacterial qualities. Conversely, the inorganic components on the smear layer may be eliminated using chelating agents. The smear layer can be removed with this irrigation technique, although the apical third is where it is least successful. Irrigating solutions must come into direct touch with the entire root canal wall surfaces when employing irrigant activation devices, particularly in the apical regions of small root canals. Irrigants play a crucial role in the canal system since they facilitate the seepage of medications into the system while cleaning the canal. Thus, prior to the obturation process, the canal must be in good health. These days, a lot of irrigants have been researched; as a result, a compilation of the different sources that are available and an examination of their effects in vivo and in vitro are necessary. Since the appropriate activation and features of the root canal system are critical to the effectiveness of endodontic root canal therapy, the relationship between irrigants and canal cleanliness is critical. As a result, the use of modern-day irrigating solutions along with benefits and drawbacks are included in this review.
