ÖZET
 Amaç: Bu çalışmanın amacı, kök kanallarından kalsiyum hidroksidin (KH) uzaklaştırılmasında farklı irrigasyon solüsyonu kombinasyonlarının etkinliğini karşılaştırmaktır. Gereç ve Yöntemler: Seksen sekiz adet alt premolar dişin kök kanalları genişletildi ve kökler, diş uzun aksı boyunca ikiye ayrıldı. Kök kanal yüzeyinin apikal 1/3'lük kısmında standart bir yapay oluk hazırlandı. Oluklar, KH ile doldurulduktan sonra kök yarıları birleştirildi. Ardından kanallar tamamen KH ile dolduruldu. Örnekler, 4 deney (n=20) ve 2 kontrol grubuna (n=4) ayrıldı. Gruplarda; Grup 1: %1 fitik asit (IP6), Grup 2: %1 IP6 ve devamında %5 sodyum hipoklorit (NaOCl), Grup 3: %17 etilendiamintetraasetik asit (EDTA) ve Grup 4: %17 EDTA ve devamında %5 NaOCl olacak şekilde 30-G IrriFlex irrigasyon iğnesi ile irrigasyon yapıldı. Toplam irrigasyon solüsyonlarının hacmi, her grupta 20 mL olacak şekilde belirlendi. Köklerin tekrar ayrılmasından sonra yapay oluklarda kalan KH miktarı, bir stereo mikroskop (x40) altında değerlendirildi. Veriler, daha sonra Shapiro-Wilk ve Kruskal-Wallis H testleri kullanılarak istatistiksel olarak analiz edildi (p0,05). Sonuç: EDTA, IP6 ve bunların NaOCl kombinasyonları, KH uzaklaştırma konusunda tam bir başarı sağlamadı. Bu çalışmanın bulgularına göre KH uzaklaştırmada %1 IP6'nın, EDTA'ya alternatif bir şelasyon ajanı olabileceği görüldü.

ABSTRACT
 Objective: The aim of current study was to compare the efficacy of different irrigation solution combinations in removal of calcium hydroxide (CH) from root canals. Material and Methods: Root canals of eighty-eight mandibular premolar teeth were instrumented and split into 2 halves. A standard artificial groove was prepared on the apical third of the root canal surface. After the grooves were filled with CH, the root halves were combined. Then the root canals were filled entirely with CH. The specimens were divided into 4 experimental groups (n=20) and 2 control groups (n=4). The teeth were irrigated with a 30- G IrriFlex irrigation needle using the following irrigants: Group 1: 1% phytic acid (IP6), Group 2: 1% IP6 followed by 5% sodium hypochlorite (NaOCl), Group 3: 17% ethylenediaminetetraacetic acid (EDTA), Group 4: 17% EDTA followed by 5% NaOCl. The volume of the total irrigation solutions was 20 mL in each group. After the disassembling of the root halves, the amount of remaining CH in the artificial grooves was evaluated under a stereo microscope (x40). The data were then analyzed statistically using Shapiro-Wilk and Kruskal-Wallis H tests (p0.05). Conclusion: The combinations of chelating agents and NaOCI did not result in improvement in terms of cleanliness. According to the present study's findings, it can be proposed that 1% IP6 can be an alternative irrigation solution to EDTA in removing CH.
