Amaç: Bu çalışmanın amacı, kök kanal tedavisi sırasında sodyum hipoklorit ve klorheksidin solüsyonlarının etkileşimi sonucu oluşan turuncu-kahverengi para kloroanilin çökeltisinin (PKA) uzaklaştırılmasında askorbik asitin (AA) etkisini belirlemektir.
Gereç ve Yöntem: PKA, laboratuvar koşullarında cam tüplerde 1.25 mL %2.5'lik sodyum hipoklorit ve 1.25 mL %2'lik klorheksidin çözeltileri karıştırılarak elde edildi. %5-30 arasında değişen farklı konsantrasyonlarda AA çözeltileri hazırlandı ve bu çözeltilerin kök kanalındaki PKA çözünürlüğü üzerindeki etkisi gravimetrik yöntemle belirlendi. Ayrıca, belirli mol oranlarında AA, gliserin ve deiyonize suyun (AA: Gli: H2O) 70 °C'de 1 saat karıştırılması ve sürenin sonunda oda sıcaklığına soğutulmasıyla derin ötektik bir çözücü sistemi (DÖÇ) elde edildi; bu sistemin AA çözeltisine göre daha etkili bir çözücü sistemi olduğu düşünüldü. DES'in PCA çözünürlüğü üzerindeki performansı aynı yöntem kullanılarak değerlendirildi.
Bulgular: 25 °C'de sabit hacimde sodyum hipoklorit ve klorheksidin ile hazırlanan PKA'ya belirli hacimde serum fizyolojik uygulanarak hazırlanan kontrol grubunda, PKA'nın yaklaşık %27 oranında çözündüğü belirlendi. Aynı şekilde hazırlanan PKA'ya belirli hacimde AA uygulandığında, AA konsantrasyonundaki artışla bu oranın yaklaşık %55'e çıktığı belirlendi. Ayrıca, belirli hacimde DÖÇ uygulanan PKA'da %80'in üzerinde bir çözünürlük elde edildi.
Sonuç: Kanal içerisinde oluşan PKA’nın uzaklaştırılmasında irrigasyon çözücüsü olarak yüksek konsantrasyonlu AA solüsyonunun kullanılabileceği, ayrıca DÖÇ sisteminin AA’ya kıyasla PKA’nın çözündürülmesinde daha etkili bir çözücü olma potansiyeline sahip olduğu bulunmuştur.

Objectives: To determine the effect of ascorbic acid (AA) on the removal of orange-brown precipitate (PCA) formed by the interaction of sodium hypochlorite (SH) and chlorhexidine (CHX) during root canal treatment.
Materials and Method: PCA was obtained by mixing 1.25 mL of 2.5% SH and 1.25 mL of 2% CHX in glass tubes. Different concentrations of AA ranging from 5-30% were prepared and the effect of these solutions on PCA solubility was determined by gravimetric method. In addition, a deep eutectic solvent system (DES) was obtained by mixing certain mole ratios of AA, glycerin and deionized water at 70 °C for 1 h and cooling to room temperature at the end of the time. The performance of DES on the solubility of PCA was evaluated using the same method.
Results: In control group prepared with a certain volume of physiological saline applied to PCA at constant volume at 25 °C, it was determined that PCA dissolved approximately 27%. When a certain volume of AA was applied to the PCA the same way, it was determined that this rate increased to approximately 55% with the increase in the concentration of AA. In addition, a solubility of over 80% was achieved in PCA to which a certain volume of DES was applied.
Conclusion: High concentrations of AA can be used as an irrigating solvent for the removal of PCA and it was also found that DES system has the potential to be a more effective solvent for PCA solubilization compared to AA.
