It helps to remove the inorganic substances by chelation of calcium ions (EDTA-Ca). It helps to clean the canal wall by effectively removing the smear layer produced during instrumentation by endodontic files. It helps in the smooth instrumentation of canals because of lubricating properties. The lubricating action is because of the water-soluble base, which helps in minimizing the binding of Endodontic instruments during the chemo-mechanical shaping of canals. It provides a synergistic effect when used in combination with sodium hypochlorite. It releases oxygen from carbamide peroxide and produces the effervescent effect which helps in easy removal of vital & necrotic pulp tissue remnant, debris, and dentinal flakes.
