Comparative Evaluation of the Shaping Ability of Five Different Nickel-Titanium Rotary File Systems in Simulated Canals
Abstract
Objectives: The aim of this study was to compare the simulated canal shaping efficiencies of five different NiTi rotary file systems.
Materials and Methods: In the study, 100 transparent resin blocks with J-shaped canals were randomly divided into five groups (n=20). Simulated canals were shaped with VDW.Rotate (VR), TruNatomy (TRN), HyFlex CM (HF), EdgeFile X7 (EF), or ProTaper Next (PTN) files. Ten measuring points were detected on the pre- and post-preparation images taken from the blocks and superimposed. After preparation, the total canal width and the amount of transportation were calculated for the determined measuring levels. Zipping and ledge formation, instrument fracture and deformation, and change in working length were evaluated. The data were statistically analyzed with the Kolmogorov-Smirnov test, one-way ANOVA, Tukey test, Chi-Square test, and a Monte Carlo version of the Fisher Exact tests. The error level was taken as 0.05.
Results: There were significant differences between the groups at all measuring levels in terms of total canal width after instrumentation (p = 0.001). Significant differences in the amount of transportation were found between the groups (p = 0.001) except at levels 4 (p = 0.169) and 10 (p = 0.054). Zip and instrument fractures did not occur in any group. 3 EF size 25/.04 files were deformed (p = 0.021). There was no significant difference between the groups in terms of ledge formation and working length change (p > 0.05).
Conclusions: According to findings obtained in the study, transportation occurred at all 10 measuring levels with all file systems used. HF and EF systems were found to be more reliable in terms of transportation in the middle and coronal regions. Wider canal preparation was obtained with the PTN system in the middle and coronal regions.

Beş Farklı Nikel-Titanyum Döner Eğe Sisteminin Yapay Kanallarda Şekillendirme Etkinliklerinin Karşılaştırmalı Olarak Değerlendirilmesi
Abstract
Amaç: Bu çalışmanın amacı, beş farklı NiTi döner eğe sisteminin yapay kanalları şekillendirme etkinliklerinin karşılaştırılmasıdır.
Gereç ve Yöntem: Çalışmada 100 adet J şekilli kanala sahip şeffaf rezin blok, rastgele beş gruba ayrıldı (n=20). Yapay kanallar VDW.Rotate (VR), TruNatomy (TRN), HyFlex CM (HF), EdgeFile X7 (EF) veya ProTaper Next (PTN) eğeleriyle şekillendirildi. Bloklardan alınan ve çakıştırılan preparasyon öncesi ve sonrası görüntülerinin üzerinde 10 ölçüm seviyesi tespit edildi. Preparasyon sonrası toplam kanal genişliği ve transportasyon miktarı belirlenen ölçüm seviyeleri için hesaplandı. Zip, basamak oluşumu, alet kırığı, deformasyon ve çalışma boyunda meydana gelen değişim değerlendirildi. Veriler Kolmogorov-Smirnov testi, tek yönlü varyans analizi, Tukey testi, Khi-Kare testi ve Fisher Exact testlerden Monte Carlo modeliyle istatistiksel olarak analiz edilerek yanılma düzeyi 0,05 olarak alındı.
Bulgular: Tüm ölçüm seviyelerinde preparasyon sonrası toplam kanal genişliği yönünden gruplar arasında anlamlı farklar bulundu (p = 0,001). Seviye 4 (p = 0,169) ve 10 (p = 0,054) dışındaki ölçüm seviyelerinde gruplar arasında transportasyon miktarı açısından önemli farklılıklar bulundu (p = 0,001). Hiçbir grupta zip ve alet kırığı oluşmadı. 3 tane EF 25/.04 boyutlu eğe deforme oldu (p = 0,021). Basamak oluşumu ve çalışma boyu değişimi yönünden ise gruplar arasında anlamlı fark gözlenmedi (p > 0,05).
Sonuçlar: Çalışmada elde edilen bulgulara göre kullanılan tüm eğe sistemleriyle 10 ölçüm seviyesinde de transportasyon meydana geldi. HF ve EF sistem orta ve koronal bölgede transportasyon yönünden daha güvenilir bulundu. PTN sistemiyle orta ve koronal bölgede daha geniş kanal preparasyonu elde edildi.
