FRACTURE RESISTANCE OF ROOTS AFTER INSTRUMENTATION WITH TWO NICKEL-TITANIUM ROTARY SYSTEMS AT DIFFERENT WORKING LENGTHS

Öz:

Amaç: Bu çalışmanın amacı; iki döner eğe sistemi ile farklı çalışma boylarında genişletilmesi sonrasında köklerin gösterdikleri kırılma direncini değerlendirmektir. Gereç ve Yöntem: Bu çalışmada 112 adet iki köklü üst küçük azı dişi kullanıldı. Tüm dişler çalışma boyları 14 mm ve 16 mm olacak şekilde iki ana gruba ayrldı. Her bir ana grup her birinde 16 diş olacak şekilde ProTaper Universal (PTU), ProFile GT Series X (GTX) ve K-flexofiles ile genişletilmek üzere 3 alt gruba ayrıldı (n=16). 14 mm ve 16 mm çalışma boyuna ayarlanmış 2 kontrol grubunda ise genişletme yapılmayan 8er diş bulunmaktaydı. Dişler genişletildikten sonra her bir örneğe dik gelecek şekilde dakikada 1 mm hızla yük uygulandı ve kırılmanın gerçekleştiği değer kaydedildi. Verilerin istatistiksel analizi için Kruskal-Wallis (p< 0.05) ve Mann Whitney U testleri (p< 0.001) kullanıldı. Bulgular: Kontrol grupları deney gruplarına göre kırılmaya istatistiksel olarak daha fazla direnç gösterdi (p< 0.001). PTU+16 mm grubu diğer gruplara göre kırılmaya istatistiksel olarak daha az direnç gösterirken (p< 0.001) diğer deney grupları arasında istatistiksel olarak anlamlı bir fark yoktu (p= 0.012). Sonuç: İki köklü üst küçük azı dişlerin kanalları genişletilirken PTU döner eğelerin 16 mmlik aktif çalışan kısmının tamamının kullanıldığı köklerin kırılmaya yatkın hale gelebileceği gösterilmiştir.

FARKLI ÇALIŞMA BOYLARINDA İKİ DÖNER EĞE SİSTEMİ İLE GENİŞLETME SONRASI KÖKLERİN KIRILMA DİRENCİNİN İNCELENMESİ

Öz:

Background and Aim: The aim of the study was to evaluate the fracture resistance of roots after instrumentation with two nickeltitanium rotary systems at different working lengths.Materials and Methods: One hundred-twelve human maxillary two-rooted premolars were used. Teeth were divided into 2 main groups according to their working lengths, (14 or 16 mm). Each group was then assigned into 3 subgroups to be prepared with different root canal instruments [ProTaper Universal (PTU), ProFile GT Series X (GTX), and K-flexofiles] (n=16). The remaining teeth were used as the control groups. The specimens were loaded vertically at 1 mm/min crosshead speed until root fracture occurred. Data were evaluated statistically using Kruskal-Wallis and Mann Whitney U (p < 0.001) tests. Results: Fracture resistance of control groups were higher than that of all experimental groups (p< 0.001). PTU+16 mm group was found less resistant to fracture than other groups (p< 0.001) whereas no statistically significant differences were found among other experimental groups (p= 0.012). Conclusion: Fracture resistance could decrease whilst the active 16 mm of the instrument is used inside the canal especially with PTU rotary system in two-rooted maxillary premolars.
