In vitro efficiency of endodontic irrigation solutions on protein desorption

摘要: Summary The use of irrigating solutions is widely accepted as a necessary adjunct to biomechanical preparation obtain adequate cleansing the root canal system. In this study, efficiency three was tested in an vitro experimental system for removal protein from apatite surfaces: Salvizol (a bis-dequalinium acetate solution) and sodium hypochlorite at 0.5, 1, 3 6% pH 7.4 11.5. Buffered Tris-HCl 11.5 were used controls. All chemicals showed rapid kinetic effects since no variation process could be detected after 5 min. least efficient solution it induced only 2% desorption. Sodium increased with concentration reach 70% desorption surface. In general, alkaline more than buffered ones, ionic strength did not appear have major effect on process.
