Investigating The Antimicrobial Activity Of Different Root Canal Filling Pastes In Deciduous Teeth.

Background: The antiseptic property of root canal filling materials is very important for the removal of residual pathogens from root canals. The aim of the current study was to investigate the antimicrobial activity of mineral trioxide aggregate (MTA), calcium hydroxide (CH), Metapex, zinc oxide eugenol (ZOE), and CEM-cement.

Materials And Methods: Four standard bacterial strains including (ATCC 6538), (ATCC 29212), (ATCC 27853), and (ATCC 6633) and (ATCC 10231) were used.
