The effect of a fluorocarbon surfactant on the surface tension of the endodontic irrigant, sodium hypochlorite

Abstract

Abstract A fluorochemical surfactant was used to reduce the surface tension of 4 per cent sodium hypochlorite from 70 mN/m to 27 mN/m. The solution was stable for more than one month when tested for reduced surface tension, available chlorine, and protein solvent ability. No chemical residue remained on the root canal wall when viewed using scanning electron microscopy.
