Amaç: Reciproc Blue (RPC Blue), K3XF ve ProTaper Universal Retreatment (PTR) nikeltitanyum (NiTi) eğe sistemlerinin gütaperka ve kanal patı uzaklaştırma kabiliyetini ve gütaperka ve sealer uzaklaştırmaları için gerekli zamanı karşılaştırmaktır. Gereç ve Yöntemler: Tek ve düz kök kanalına sahip toplam 60 maksiller santral diş NiTi döner eğeler ile #40,04 boyutunda enstrumenta edildi ve sürekli ısıyla kondensasyon tekniğine uygun olarak dolduruldu. Gütaperka ve kanal patının çıkarılması, test edilen 3 farklı NiTi sistemlerinden biri kullanılarak gerçekleştirildi: RPC Blue, K3XF ve ya PTR. Dişlerden kesit alındı ve dijital görüntüler elde edildi. Görüntüler AutoCAD (Autodesk, San Rafael, CA, ABD) yazılımı kullanılarak analiz edildi. Ayrıca, gütaperka ve kanal patı uzaklaştırmak için gereken toplam süre bir kronometre ile hesaplandı. Veriler 2-ways varyans analizi (ANOVA) ve Duncan testi kullanılarak %5 anlamlı düzeyde istatistiksel olarak analiz edildi. Bulgular: RPC Blue grubunda toplam yeniden tedavi süresi diğer gruplarla karşılaştırıldığında anlamlı olarak daha kısa idi. Toplam arda kalan gütaperka ve kanal patı açısından gruplar arasında anlamlı farklılık bulundu. RPC Blue ve PTR grupları, K3XF grubuna kıyasla anlamlı derecede daha az arda kalan gütaperka ve kanal patı bıraktı. Sonuç: Bu çalışmanın sınırları dâhilinde, RPC Blue ve PTR gruplarında K3XF grubuna kıyasla anlamlı derecede daha az arda kalan gütaperka ve kanal patı görüldü. RPC Blue grubunda, gütaperka ve kanal patının uzaklaştırılması için gereken süre içinde diğer gruplardan anlamlı derecede daha kısa olduğu belirlenmiştir.

Objective: To compare the gutta-percha and sealer removal ability of Reciproc Blue (RPC Blue), K3XF, and ProTaper Universal Retreatment (PTR) nickel-titanium (NiTi) systems and the time required for gutta-percha and sealer removal. Material and Methods: A total of 60 human maxillary central incisors with single and straight root canals were instrumented up to #40.04 using NiTi rotary files and obturated using the continuous wave of condensation technique. Removal of the gutta-percha and sealer was performed using one of the following NiTi systems: RPC Blue, K3XF, or PTR. The teeth were sectioned, and digital images were captured. The photographs were analyzed using AutoCAD software (Autodesk, San Rafael, CA, USA). Also, the total time required for gutta-percha removal was calculated by a chronometer. The data was analyzed statistically using 2-way analysis of variance (ANOVA) and the Duncan test at a 5% significant level. Results: The total retreatment time was significantly shorter in the RPC Blue group compared with the other groups. There was a significant difference among the groups according to the total residual gutta-percha and sealer. The RPC Blue and PTR groups left significantly less gutta-percha and sealer remnants than the K3XF group. Conclusion: Within the limitations of this study, the RPC Blue and the PTR groups showed less residual gutta-percha and sealer than the K3XF group. The RPC Blue group was significantly faster than the other groups in the time required for gutta-percha and sealer removal.
