%5.25 Sodyum hipoklorit ile setrimit ve polipropilen glikol içeren sodyum hipokloritin pH düzeylerinin incelenmesi

AMAÇ: Bu çalışmanın amacı, %5.25 sodyum hipoklorit (NaOCl) ile setrimit ve polipropilen glikol içeren NaOCl’nin pH değerlerinin 1, 2, 5 ve 7 gün zaman aralıklarında değerlendirilmesidir.GEREÇ VE YÖNTEM: %5.25 NaOCl ve setrimit ile polipropilen glikol içeren NaOCl solüsyonları, 1’er mL hacimlerde 1.5 mL’lik Eppendorf tüplere ayrı ayrı koyuldu. Değişik zaman aralıklarında (1, 2, 5 ve 7 gün) pH değerleri pH-metre ile ölçüldü. Ölçümler her bir örnek için 3 kez tekrarlanarak ortalama değerler kaydedildi. Her ölçüm öncesi pH-metre kalibre edildi.BULGULAR: Setrimit ile polipropilen glikol içeren NaOCl karışımının pH değerleri, %5.25 NaOCl’ye göre istatistiksel olarak anlamlı şekilde daha yüksek çıktı (p<0.05). Her iki solüsyonda da 1, 2, 5 ve 7. günlerdeki pH değerleri arasında istatistiksel olarak farklılık bulunamadı (p>0.05). Setrimit ve polipropilen glikol içeren sodyum hipokloritin 1. ve 7. günlerdeki pH değerleri sırasıyla, 12.67±0.25 ve 12.65±0.30 iken; %5.25 NaOCl’nin aynı günlerdeki pH değerleri sırasıyla, 11.98±0.22 ve 11.95±0.24 olarak saptandı.SONUÇ: Sonuç olarak setrimit ve polipropilen glikol içeren NaOCl solüsyonunun pH değeri, %5.25 NaOCl solüsyonuna göre daha yüksek bulundu.

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

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.
