Item “Concentración de cloro activo en presentaciones comerciales de hipoclorito de sodio de uso endodóntico”(Universidad Nacional de Trujillo, 2022) Fuentes Arteaga, Carlos Alberto; Guillén Galarza, Manuel FernandoObjective: To determine if there is a variation in the concentration of active chlorine in the commercial presentations of sodium hypochlorite for endodontic use with respect to what is indicated on the packaging. Methodology: This present work is a cross-sectional, quantitative rational, observational and laboratory study developed in the Laboratory of the Faculty of Chemical Engineering of the National University of Trujillo (LASACI). Material and method: A total of 33 samples of sodium hypochlorite for endodontic use, of 3 different concentrations (1%, 3% and 5%) were evaluated, being 11 containers of sodium hypochlorite for each concentration. Each sample was evaluated with the same procedure, whose instrument is a formula that allows determining the concentration (%) of active chlorine present in each sample studied. Results: The real active chlorine concentration of the 1% sodium hypochlorite containers on average 0.781%, with a standard deviation of 0.148%; while the real active chlorine concentration of the 3% sodium hypochlorite containers is on average 0.767%, with a standard deviation of 0.072%, and the real active chlorine concentration of the 5% sodium hypochlorite containers is on average 0.877%, with a standard deviation of 0.063%. Conclusions: There is variation in the concentration of active chlorine in commercial presentations of sodium hypochlorite for endodontic use with respect to what is indicated on its packaging.
