[Comparative evaluation of antimicrobial activity of root canal irrigation agents].

A comparative study of the antimicrobial activity of different antiseptics for root canal irrigation: chlorhexidine bigluconate solution in 6 concentrations (2.0-1.0-0.5-0.2-0.1-0.02%), two sodium hypochlorite formulations: "Parcan" (France) and "Hypochloran-3" (Russia), and stabilized EDTA solution (EDTA Solutions (Korea)) was carried out. The results indicate that the level of antimicrobial activity of chlorhexidine is directly proportional to its concentration. Sodium hypochlorite tends to be more effective in compare with chlorhexidine. EDTA Solutions has a pronounced antimicrobial activity against all strains.
