Amaç: Bu çalışmanın amacı, WaveOne (Dentsply Maillefer, Ballaigues, İsviçre),
Reciproc (VDW, Münih, Almanya) ve Twisted File Adaptive (Axis/SybronEndo,
Orange, CA, ABD) döner sistem nikel titanyum (Ni-Ti) eğelerin çift kurvatürlü
(S-şekilli) kanallarda döngüsel yorgunluğa bağlı kırılma dirençlerinin
karşılaştırılmasıdır.

Gereç ve Yöntem: Bu çalışmada 45 adet (WaveOne primary, Reciproc R25 ve Twisted
File Adaptive M-L1) eğe kullanıldı. Her
bir sistemden 15 eğe kırılıncaya kadar çift kurvatürlü (S-şekilli) yapay bir
kanalda döndürüldü. Kırılıncaya kadar olan tur sayısı hesaplandı ve kırılmış
parçaların uzunluğu kaydedildi. Veriler, ANOVA ve Tukey post hoc testleri
kullanılarak istatistiksel olarak analiz edildi. İstatistiksel anlamlılık
düzeyi p < 0.05 olarak belirlendi.

Bulgular: Reciproc R25 eğeleri hem apikal hem de koranal kurvatürde, WaveOne
primary ve Twisted File Adaptive M-L1 eğelerine göre döngüsel yorgunluğa karşı
daha dirençli bulundu (p < 0.05).
WaveOne primary ve Twisted File Adaptive M-L1 eğeleri arasında her iki
kurvatürde de istatistiksel olarak anlamlı farklılık saptanmadı (p > 0.05). Bütün gruplar arasında
aletlerin kırılmış fragmanlarının uzunluğu istatistiksel olarak benzer bulundu
(p > 0.05).

Sonuç: Reciproc R25 eğeler, WaveOne primary ve Twisted File Adaptive eğelere
göre çift kurvatürlü kanallarda kırılmaya karşı daha dirençli bulundu.

 COMPARISON
OF THE CYCLIC FATIGUE RESISTANCE OF WAVEONE, RECIPROC AND TWISTED FILE ADAPTIVE
FILES IN CANALS WITH  A DOUBLE
CURVATURE (S-SHAPED)

ABSTRACT

Aim: The purpose of this study was
to compare the cyclic fatigue resistance of WaveOne (Dentsply Maillefer,
Ballaigues, Switzerland), Reciproc (VDW, Münich, Germany) and Twisted
File Adaptive (Axis/SybronEndo, Orange, CA, USA) nickel titanium (Ni-Ti)
systems in canals with a double curvature.

Materials and Methods: Forty five rotary NiTi files (WaveOne
primary, Reciproc R25 and Twisted File Adaptive M-L1) were used in this study. Fifteen files from each system were rotated in canals
with a double curvature until fracture. The number of cycles to fracture was
calculated and the length of each fractured fragment was recorded. The data
were statistically analysed using ANOVA and Tukey post hoc tests. The
statistical significance level was set at p
< 0.05.

Results: The Reciproc R25 file had higher cyclic
fatigue resistance than WaveOne primary and Twisted File Adaptive in the apical and coronal curvatures (p < 0.05). There was no significant
distinction in the cyclic fatigue resistance of the WaveOne primary and Twisted
File Adaptive files in either the apical or coronal curvature. The length of
the fractured part of the instruments was similar among all the groups (p > 0.05).

Conclusion: The
Reciproc R25 file indicated better cyclic fatigue resistance than WaveOne
primary and Twisted File Adaptive in an artificial canal with an S-shape.

Keywords: Cyclic fatigue, Reciproc,
WaveOne, S-shaped canal.
