Özet

Objective: This study aimed to evaluate the effect of sodium hypochlorite on the cyclic fatigue resistance of BioRace (BR) files according to taper. Methods: BR 25.04 and 25.06 files were divided into the following groups: group 1, 20 BR 25.04 with no immersion in NaOCl; group 2, 20 BR 25.04 with immersion in 5.25% NaOCl at 37 °C ±1 °C for 5 min; group 3, 20 BR 25.06 with no immersion; and group 4, 20 BR 25.06 with immersion in 5.25% NaOCl at 37 °C ±1 °C for 5 min. The instruments were applied to a stainless-steel artificial root canal of 60° curvature and 5-mm radius. The time to failure (TTF) in seconds and number of cycles to failure (NCF) were recorded. Results: The cyclic fatigue resistance of BR 25.04 was significantly higher than that of BR 25.06. The TTF and NCF values were significantly higher in group 1 than in groups 2 and 3 and in group 2 than in group 4. However, neither value differed significantly between groups 3 and 4 (p>0.05). Conclusion: Taper and sodium hypochlorite affected the cyclic fatigue resistance of BR.

Abstract

Amaç: Bu çalışmanın amacı sodyum hipokloridin farklı taperlara sahip olan BioRace (BR) döner alet sisteminin döngüsel yorgunluğuna etkisini değerlendirmektir. Yöntemler: BR 25,04 ve BR 25,06 enstrümanlarının döngüsel yorgunlukları, farklı koşullarda test edildi. Grup 1, BR 25,04 nolu eğe hiç bir solüsyonda bekletilmeden; grup 2: BR 25,04 %5,25 NaOCl solüsyonunda 37 °C ±1 °C’de 5 dakika bekletilerek; grup 3: BR 25,06 hiç bir solüsyonda bekletilmeden; grup 4: BR 25,06 %5,25 NaOCl solüsyonunda 37 °C ±1 °C’de 5 dakika bekletildikten sonra 60° kurvatür açılı and 5 mm kurvatür yarıçaplı paslanmaz çelik bloktan üretilmiş eğimli olukta test edildi. Her bir eğenin kırılana kadarki döngü sayısı (NCF) ve kırılana kadarki süresi (TTF) saniye cinsinden kaydedildi. Elde edilen veriler istatistiksel analizler ile değerlendirildi. Bulgular: BR 25,04 eğesinin döngüsel yorgunluk direnci, BR 25,06’dan istatistiksel olarak daha yüksektir. TTF ve NCF değerleri grup 1 > grup 2 , grup 1 > grup 3 , grup 2 > grup 4 şeklinde bulundu. Buna karşılık, grup 3 ve grup 4 arasında istatistiksel olarak anlamlı bir fark yoktu. Sonuç: Bu çalışmanın sınırları doğrultusunda BR ensturmanlarının taperı ve sodyum hipokloritte bekletilmesi aletin döngüsel yorgunluğuna etki etmektedir.
