Abstract

Amaç: Bu çalışmanın amacı, dört farklı final irrigasyon aktivasyon yönteminin—standart iğne irrigasyonu (SNI), pasif ultrasonik irrigasyon (PUI), EndoActivator (EA) ve EDDY—simüle immatür apeksli dişlerde irrigasyon solüsyonlarının apikal ekstrüzyonu üzerindeki nicel etkilerini değerlendirmektir.
Materyal ve yöntemler: Tek kanallı, tek köklü 60 diş ProTaper Next sisteminin X3 eğesine kadar genişletildi. İmmatür apeks simülasyonu için Gates Glidden frezleri (#1–#6) kullanılarak apikal çap 1,5 mm’de standartlaştırıldı. Kanallar sırasıyla %2 NaOCl, %17 EDTA ve distile su ile irrige edildi. Her bir diş, kök ucuna yerleştirilen 27G iğne aracılığıyla drenaja izin verecek şekilde bir Eppendorf tüp kapağına monte edildi. Tüpler NaOCl ile dolduruldu. Örnekler, irrigasyon aktivasyon yöntemine göre rastgele dört gruba ayrıldı (n=15): SNI, PUI, EA ve EDDY. Tüm gruplarda toplamda 6 ml %2 NaOCl, 3 dakika süreyle aktive edildi. Ekstrüze olan irrigasyon solüsyonu, insülin şırıngası ile toplandı ve mililitre cinsinden kaydedildi.
Verilerin dağılımı Kolmogorov-Smirnov testi ile değerlendirildi. İstatistiksel analiz Kruskal-Wallis testi kullanılarak gerçekleştirildi (p<0,05).
Bulgular: En yüksek irrigasyon solüsyonu ekstrüzyon ortalaması SNI ve PUI gruplarında gözlenirken, EA grubu diğer yöntemlere kıyasla daha düşük ekstrüzyon sergiledi. Bununla birlikte, ekstrüze irrigasyon solüsyonu hacmi açısından yöntemler arasında istatistiksel olarak anlamlı bir fark bulunmadı (p>0,05).
Sonuç: Bu çalışma, immatür apeksli dişlerde test edilen tüm irrigasyon aktivasyon yöntemlerinin apikal ekstrüzyon kontrolünde benzer performans gösterdiğini ortaya koymaktadır.

Efficacy of Different Irrigation Activation Methods on the Amount of Extruded Irrigation Solution in Teeth with Simulated Immature Apex

Abstract

Objective: The study aimed to quantitatively evaluate the effects of four final irrigation activation methods—standard needle irrigation (SNI), passive ultrasonic irrigation (PUI), EndoActivator (EA), and EDDY—on apical irrigant extrusion in teeth with simulated immature apex.

Materials and Methods: Sixty single-rooted teeth with single canals were prepared up to the X3 instrument of the ProTaper Next system. To simulate open apices, Gates Glidden burs (#1–#6) were used, standardizing the apical diameter to 1.5 mm. The canals were irrigated with 2.5% NaOCl, 17% EDTA, and distilled water. Each tooth was mounted in the cap of an Eppendorf tube, allowing drainage through a 27G needle positioned at the root tip. The tubes were filled with NaOCl. Samples were randomly divided into four groups (n=15) based on the irrigation activation method: SNI, PUI, EA, and EDDY. In all groups, 6 ml of 2.5% NaOCl was activated over 3 minutes. The extruded irrigant was collected using an insulin syringe, and the volume was recorded in milliliters.

Results: Data normality was assessed with the Kolmogorov-Smirnov test. Statistical analysis was performed using the Kruskal-Wallis and Mann-Whitney U tests (p<.05). The highest mean irrigant extrusion occurred in the SNI and PUI groups, while the EA group exhibited lower extrusion compared to others. However, no statistically significant difference was found among the methods regarding the mean volume of extruded irrigant (p>.05).

Conclusion: This study highlights that all tested irrigation activation methods perform similarly in controlling apical extrusion in teeth with immature apex.
