COMPARISON OF FOUR DIFFERENT ENDODONTIC ROTARY SYSTEMS IN TERMS OF CYCLIC FATIGUE

Öz:

Objectives: The aim of this study was to compare four endodontic rotary systems in terms of cyclic fatigue. Material and Methods: 25/.08 Twisted File (TF), TF Adaptive, Reciproc and WaveOne rotary files were used to test the cyclic fatigue strength in this study. Four different artificial canals, compatible with the file size and taper, were created, with the curvature angle and radius of 450-2 mm, 600-2 mm, 450-5 mm and 600-5 mm, respectively. The front surface of the artificial canals was covered with a removable glass plate. The files were operated in the canals according to their own working principles until they fractured. The fracture time was determined by using a chronometer with 1/100 second accuracy and the cyclic fatigue strength was evaluated according to the time until fracture occurs. A total of 40 files, 10 in each canal, were used in each group. SPSS program was used for statistical analysis. Mann-Whitney U test was applied for pairwise comparisons. Bonferroni correction was applied and P<0.008 was considered as statistically significant. Results: In all canals, fracture time was the highest for Reciproc files, followed by WaveOne, TF Adaptive and TF files, respectively. For the canal curvature of 450-2 mm, the Reciproc files were significantly more resistant to fracture than the others. While there was no significant difference between TF Adaptive and TF, WaveOne was significantly more resistant than both groups. In canals with the curvature of 600-2 mm and 450-5 mm Reciproc and WaveOne were significantly more resistant to fracture than TF Adaptive and TF. In addition, TF Adaptive was significantly more resistant than TF. For the curvature of 600-5 mm, the difference between all groups was significant. Conclusions: Regardless of the canal curvature, the Reciproc exhibited the highest cyclic fatigue strength, while the TF showed the lowest fatigue strength.

Dört Farklı Endodontik Döner Eğe Sisteminin Döngüsel Yorgunluk Açısından Karşılaştırılması

Öz:

Amaç: Bu çalışmanın amacı dört endodontik döner eğe sisteminin döngüsel yorulma dayanımının karşılaştırılmasıdır. Gereç ve Yöntemler: Çalışmamızda döngüsel yorulma dayanımını test etmek üzere 25/.08 Twisted File (TF), TF Adaptive, Reciproc ve WaveOne eğeler kullanıldı. Eğe boyutunu ve taperını taklit edecek şekilde, eğrilik açısı ve yarıçapı sırasıyla 45°-2 mm, 60°-2 mm, 45°-5 mm ve 60°-5 mm olan 4 farklı yapay kanal oluşturuldu. Yapay kanalların ön yüzeyi takılıp çıkarılabilir cam bir levha ile örtüldü. Eğeler kanallar içerisinde kendi çalışma prensiplerine göre kırılana kadar çalıştırıldı. 1/100 saniye hassasiyetinde bir kronometre yardımıyla kırılma süresi tespit edildi ve döngüsel yorulma dayanımı kırılma oluşana kadar geçen süreye göre değerlendirildi. Her grupta, her kanalda 10 adet olmak üzere toplam 40 eğe kullanıldı. İstatistiksel analiz için SPSS programı kullanıldı. İkili karşılaştırmalar için Mann-Whitney U testi yapıldı. İstatistiksel anlamlılık için Bonferroni düzeltmesi uygulandı ve P<0.008 istatistiksel olarak anlamlı kabul edildi. Bulgular: Bütün kanallarda kırılma süresi Reciproc eğelerde en yüksek olup bunu sırasıyla WaveOne, TF Adaptive ve TF eğeler izledi. 45°-2 mm eğimli kanalda Reciproc eğeler kırılmaya karşı diğerlerine göre anlamlı derecede daha dayanıklıydı. TF Adaptive ile TF arasında anlamlı fark bulunmazken (P= .041), WaveOne her iki gruba göre anlamlı derecede daha dayanıklıydı. 60°-2 mm ve 45°-5 mm eğimli kanallarda Reciproc ve WaveOne, kırılmaya karşı TF Adaptive ve TF’ye göre anlamlı derecede daha dayanıklıydı (P< .001). Ayrıca TF Adaptive da TF’ye göre anlamlı derecede daha dayanıklıydı. 60°-5 mm eğimli kanalda ise bütün gruplar arasındaki fark anlamlıydı. Sonuçlar: Kanal eğimine bağlı olmaksızın en yüksek döngüsel yorulma dayanımını Reciproc eğeler sergilerken, TF eğeler en düşük yorulma dayanımını gösterdi.
