Assessment of the pH levels of 5.25% sodium hypochlorite and sodium hypochlorite with cetrimide and polypropylene glycol

26701

OBJECTIVE: The aim of this study was to evaluate the pH of %5.25 sodium hypochlorite (NaOCl) and NaOCl with cetrimide and polypropylene glycol at 1, 2, 5 and 7 days. MATERIALS AND METHOD: One mL of %5.25 NaOCl and NaOCl with cetrimide and polypropylene glycol solutions were added into 1.5 mL Eppendorf tubes. The pH values were recorded with a pH-meter at different time intervals (1, 2, 5 and 7 days). Measurements were repeated 3 times and average values were recorded. The pH-meter was calibrated before each measurement. RESULTS: The pH value of NaOCl with cetrimide and polypropylene glycol solution was significantly higher compared with the NaOCl solution (p 0.05). For each solution, the pH values at 1, 2, 5 and 7 days were not significantly different (p 0.05). The pH values of NaOCl with cetrimide and polypropylene glycol were 12.67±0.25 and 12.66±0.30 at 1. day and 7. days, respectively, and the pH values of NaOCl were 11.98±0.22 and 11.94±0.24 at 1. day and 7. days, respectively. CONCLUSION: NaOCI solution with cetrimide and polypropylene glycol exhibited higher pH levels than the %5.25 NaOCI solution.
