ABSTRACT
 Objective: Since research on the effectiveness of replica-like files in shaping root canals is limited, this study compared the shaping effectiveness of the original WaveOne Gold (WOG) file system with the replica Scope RS Gold (SC) file system in J-shaped simulated resin blocks. Material and Methods: Root canal preparations were performed in 24 simulated J-shaped root canals using WOG (#25.07) and SC (#25.07) files (n=12). The pre- and post-operative images of the prepared root canals were superimposed. The root canals in the images were divided into 9 segments of 1 millimeter each, and a total of 18 measurements were obtained from both canal surfaces. The inner and outer root canal walls were named B and A, respectively. The total resin removal amount (TRR) (A+B), the transportation value and direction (TV) (lB-Al), and the centering ability (CA) (A/B or B/A) were calculated. One-way analysis of variance and posthoc Tukey tests were used for statistical analysis (p<0.05). Results: When TRR was evaluated, the SC instruments removed more resin in the apical, middle, and coronal thirds (p<0.05). When TV was evaluated, no difference was observed between the groups in the coronal third (p>0.05), while the SC instruments caused more transportation in the apical and middle thirds (p<0.05). Moreover, no statistically significant difference was found in terms of the instruments' CA in the apical, middle, and coronal thirds (p>0.05). Conclusion: The replicalike system exhibited significantly higher values in terms of resin removal and canal transportation.

ÖZET
 Amaç: Kök kanallarının şekillendirilmesinde replika eğelerin etkinliği ile ilgili bilimsel veriler yetersizdir, bu nedenle çalışmanın amacı, orijinal WaveOne Gold (WOG) eğe sistemi ile replika Scope RS Gold (SC) eğe sisteminin J-şekilli simüle rezin bloklardaki şekillendirme etkinliğini karşılaştırmaktır. Gereç ve Yöntemler: Yirmi dört adet simüle J-şekilli kök kanalında, WOG (#25,07) ve SC (#25,07) eğeleri kullanılarak kök kanal preparasyonları gerçekleştirilmiştir (n=12). Preparasyonu tamamlanan kök kanalların preoperatif ve postoperatif görüntüleri bilgisayar ortamında çakıştırılmıştır. Görüntülerde kök kanalları 9 adet 1 mm'lik segmentlere ayrılarak her iki kök kanalı yüzeyinden toplamda 18 ölçüm elde edilmiştir. İç ve dış kök kanal duvarları sırasıyla B ve A olarak adlandırılmıştır. Toplam rezin uzaklaştırma miktarı (TRR) (A+B), transportasyon değeri ve yönü (TV) (lB-Al) ve merkezleme yeteneği (CA) (A/B veya B/A) görüntü işleme programı kullanılarak hesaplanmıştır. İstatistiksel analizler için tek yönlü varyans analizi ve ''post hoc'' Tukey testleri kullanılmıştır (p<0,05). Bulgular: TRR değerlendirildiğinde, SC apikal, orta ve koronal üçlüde daha fazla rezin uzaklaştırmıştır (p<0,05). TV değerlendirildiğinde, koronal üçlüde gruplar arasında fark gözlenmezken (p>0,05), apikal ve orta üçlüde SC daha fazla transportasyona sebep olmuştur (p<0,05). CA değerlendirildiğinde ise SC ve WOG grupları arasında merkezde kalma oranı açısından apikal, orta ve koronal üçlüde istatistiksel olarak anlamlı farklılık bulunamamıştır (p>0,05). Sonuç: Replika sistemi rezin uzaklaştırma ve kanal transportasyonu açısından daha büyük değerler göstermiştir.
