Objective: This study aimed to assess the accuracy of the Raypex 6 (VDW GmbH, Munich, Germany) and Root ZX mini (J.Morita Corp., Tokyo, Japan) electronic apex locators (EALs) with regard to detecting root perforations in dry conditions and in the presence of irrigation solutions [2.5% sodium hypochlorite (NaOCl), 17% ethylenediaminetetraacetic acid (EDTA) and Qmix].Materials and Methods: Twenty single-rooted human teeth were perforated artificially with a 1 mm diameter in the middle region.The actual canal lengths up to the perforation site were determined, and then the teeth were embedded in an alginate mold.The electronic measurements of the perforations were obtained using a size #20 K-file for each EAL in various conditions.Results: There were significant differences between the different canal conditions in the Raypex 6 group (p<0.05),but no significant differences in the Root ZX mini group (p>0.05).There was a statistically significant difference (p<0.05) between the two EALs in the presence of EDTA solution, but no statistically significant difference between the accuracy of two EALs in the presence of other solutions and in the dry canal condition (p>0.05).Conclusion: Under the conditions of this study, both apex locators detected root canal perforations within a clinically acceptable (range of -0.18 to 0.31mm) distance from the coronal border of the perforation region.Irrigation solutions within the root canal affected the accuracy of Raypex 6, but not of Root ZX mini.Amaç: Bu çalışmanın amacı kök perforasyonunu tespit etmede kuru koşullarda ve irrigasyon solüsyonları varlığında [%2,5 sodyum hipoklorit (NaOCl), %17 etilendiamintetraasetik asit (EDTA) ve Qmix] Raypex 6 (VDW GmbH, Münih, Almanya) ve Root ZX mini (J.Morita Corp., Tokyo, Japonya) elektronik apeks bulucularının (EAB) doğruluğunu değerlendirmektir.Gereç ve Yöntemler: Yirmi adet tek köklü insan diş kökünün orta bölümünde 1 mm çapında yapay perforasyon oluşturuldu.
