ABSTRACT
Introduction:Apical extrusion of necrotic tissues to the periapical area may cause postoperative pain and flare-ups and provoke an acute inflammatory response. The purpose of this study was to evaluate the apical debris extrusion after preparing root canals with different single-file Ni-Ti systems.
Methods:A total of 45 extracted mandibular molar teeth were selected and the mesial root canals of the specimens were used for this study. The specimens were randomly divided into three groups (n = 15). 
Group 1: Glide-path preparation was performed using OneG file and the root canals were instrumented with HyFlex EDM (Colténe/Whaledent).
Group 2: The root canals were prepared with OneCurve (Micro-Mega) file after creating a glide-path with OneG.
 Group 3: OneG was used for glide-path preparation before preparing root canals with WaveOne-Gold primary file (Dentsply Maillefer).
The root canals were irrigated with 8 ml NaOCl during the preparation procedure. Apically extruded debris and irrigation solution during instrumentation was collected into pre-weighed Eppendorf tubes. The tubes were then stored in an incubator at 68 °C for 5 days for the evaporation of irrigation solution. The amount of extruded debris was calculated by subtracting the pre-instrumentation weight from the post-instrumentation weight of the Eppendorf tubes. The obtained data were analyzed using Kruskal-Wallis Test.
Results: The amount of extruded debris was not statistically different among the tested groups (P > 0.05). All tested files caused the extrusion of debris.
Conclusion: Under the conditions of this in-vitro study, there was no statistically significant difference among the HyFlex EDM, One-Curve and WaveOne-Gold primary files used with different kinematics and had different thermal treatments.  All different single Ni-Ti file systems were associated with apical extrusion of debris.
Keywords: Apical Debris extrusion, dental instruments, endodontics, HyFlex EDM, OneCurve, root canal preparation, WaveOne-Gold,.

Farklı Tek Eğe Sistemlerinin Eğri Kök Kanallarından Taşan Debris Miktarına etkisi
ÖZ
Amaç: Nekrotik dokuların periapikal bölgeye taşması post-operatif ağrı ve provoke akut enflamatuar yanıta neden olabilir. Bu çalışmanın amacı kök kanallarının farklı Ni-Ti (Nikel-Titanyum) eğe sistemleri ile şekillendirilmesi sonrasında apikal bölgeye taşan debris miktarını karşılaştırmaktır.
Gereç ve Yöntem:Bu çalışma için toplam 45 adet mandibular molar diş seçilmiş ve örneklerin mezial kök kanalları kullanılmıştır. Örnekler rastgele üç gruba ayrılmıştır (n=15).
Group 1: Kanal içerisinde OneG eğesi ile rehber yol hazırlandıktan sonra, şekillendirme işlemi HyFlex EDM OneFile ile yapılmıştır. 
Group 2: OneG eğesi ile rehber yol hazırlandıktan sonra kök kanalları OneCurve eğesi ile genişletilmiştir. 
 Group 3: Kök kanalları OneG eğesi ile rehber yol hazırlandıktan sonra WaveOne-Gold primary eğesi ile şekillendirilmiştir. 
Şekillendirme sırasında kök kanalları 8ml NaOCl solüsyonu ile yıkanmıştır. Apikalden taşan debris ve irrigasyon solüsyonu ağırlığı önceden ölçülmüş olan Ependorf tüplerinde biriktirilmiştir. Tüpler daha sonra irrigasyon solüsyonunun buharlaşması için inkübatörde 68C°’de 5 gün boyunca bekletilmiştir. Apikalden taşan debris miktarı şekillendirme sonrası tartılan Ependorf tüplerinin ağırlığından şekillendirme öncesi ağırlıkları çıkartılarak hesaplanmıştır. Elde edilen veriler istatistiksel olarak Kruskal-Wallis testi ile değerlendirilmiştir.
Bulgular:Deneysel gruplar arasından apikalden taşan debris açısından istatistiksel olarak fark bulunmamıştır (P > 0.05). Bütün gruplarda apikal debris çıkışı gözlenmiştir. 
Sonuç: Bu in-vitro çalışmanın koşulları altında farklı kinematiğe sahip ve farklı ısıl işlemler uygulanan HyFlex EDM, One-Curve ve WaveOne-Gold primary eğeleri arasında anlamlı bir fark bulunmamıştır. Bütün Ni-Ti eğe sistemleri apikalden debris taşmasına sebep olmuştur.
Anahtar Kelimeler: Apikal debris çıkışı, Endodonti, HyFlex EDM, kök kanalını hazırlama, OneCurve, WaveOne-Gold.
