Debridement in the root canal. Dissolution of pulp remnants. Removal of smear layer. Facile movements of canal instruments. Microbicidal treatment within the canal. Clearance of dentin tubules and apical area. EDTA removes smear layer, softens dentin, and facilitates the removal of calcific obstruction. Urea Hydrogen Peroxide reacts with Sodium Hypochlorite to produce oxygen bubbles that flush out debris within the canal. The lubricant medium facilitates instrument movement within the canal to eliminate instrument binding or breakage. Unclogged dentin tubules and apical area permit better penetration of root canal medicaments and fillings. Rapid cleaning and enlarging of canals because EDTA softens canal walls and removes calcium deposits. EDTA paste is easier to place into canals than EDTA liquid solution.
