Effectiveness of silver-graphene oxide nanoparticle against Enterococcus faecalis biofilms in the root canal.

Aim: This study aims to assess the effectiveness of silver-graphene oxide (AgGO) nanoparticles against Enterococcus faecalis biofilm and smear layer in comparison with 3% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX) using passive ultrasonic irrigation (PUI) technique.

Subjects And Methods: Eighty single-rooted teeth were collected, sterilized, and prepared for this study. E.
