Lab analysis compared antibacterial efficacy of sodium hypochlorite and chlorhexidine in root canals, suggesting enhanced treatment outcomes.
The antibacterial efficacy of different root canal irrigants against Enterococcus faecalis, a resilient pathogen often implicated in post-treatment infections is of interest. The effectiveness of sodium hypochlorite (NaOCl), chlorhexidine gluconate (CHX), and cetrimide was compared, both individually and in combination. The results suggest that while each irrigant has its merits, sequential use of NaOCl followed by CHX with distilled water as intermediate offers enhanced bacterial eradication. However, further research is needed to determine optimal dosages, application methods, and the most effective combinations to improve clinical outcomes and minimize post-treatment complications.
