Abstract

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.

Özet

Amaç: Bu çalışmanın amacı sodyum hipokloridin farklı taperlarasahip olan BioRace (BR) döner alet sisteminin döngüselyorgunluğuna etkisini değerlendirmektir. Yöntemler: BR 25,04 ve BR 25,06 enstrümanlarının döngüselyorgunlukları, farklı koşullarda test edildi. Grup 1, BR 25,04 nolueğe hiç bir solüsyonda bekletilmeden; grup 2: BR 25,04 %5,25NaOCl solüsyonunda 37 °C ±1 °C’de 5 dakika bekletilerek; grup3: BR 25,06 hiç bir solüsyonda bekletilmeden; grup 4: BR 25,06%5,25 NaOCl solüsyonunda 37 °C ±1 °C’de 5 dakika bekletildiktensonra 60° kurvatür açılı and 5 mm kurvatür yarıçaplı paslanmazçelik bloktan üretilmiş eğimli olukta test edildi. Her bir eğeninkırılana kadarki döngü sayısı (NCF) ve kırılana kadarki süresi(TTF) saniye cinsinden kaydedildi. Elde edilen veriler istatistikselanalizler ile değerlendirildi. Bulgular: BR 25,04 eğesinin döngüsel yorgunluk direnci, BR25,06’dan istatistiksel olarak daha yüksektir. TTF ve NCF değerlerigrup 1 > grup 2 , grup 1 > grup 3 , grup 2 > grup 4 şeklindebulundu. Buna karşılık, grup 3 ve grup 4 arasında istatistiksel olarakanlamlı bir fark yoktu. Sonuç: Bu çalışmanın sınırları doğrultusunda BR ensturmanlarınıntaperı ve sodyum hipokloritte bekletilmesi aletin döngüselyorgunluğuna etki etmektedir.
