Abstract
Objective: The researchers wanted to see whether ozonated water with ultrasonication and sodium hypochlorite can destroy Enterococcus faecalis bacteria in root canals. Materials and Methods: A total of 40 single-rooted human teeth were used. A total of 100 roots were harvested and mechanically prepared. The root canals were randomly divided into four classes (n = 10) after being infected with E. faecalis for 24 h. Each sample's MTT value was calculated. Conclusions: NaOCl and aqueous ozone provide antibacterial effects in in-vitro conditions in root canals.
