Özet
Bu çalışmanın amacı, üç farklı döner NiTi kanal aleti (K3, RaCe, ProTaper) ve bir rezin içerikli kök kanal patının (Epiphany/Resilon)
endodontik tedavi gömüş köklerin kırılmaya direncine etkilerinin karşılaştırılmasıdır. Doksan sekiz adet çekilmiş insan alt çene premolar
diş kökleri ratgele olarak 3 deney (n=28) ve 1 kontrol (n=14) grubuna ayrıldı. Dişlerin kronları mine-sement sınırından itibaren kesilerek
uzaklaştırıldı. Deney gruplarında kök kanalları K3 (K3 Grubunda), RaCe (RaCe Grubunda) ve ProTaper (ProTaper Grubunda) kök kanal
aletleri ile prepare edildi. Sonra her deney grubundan 14 dişin kök kanalı Epiphany/Resilon kök kanal dolgusu ile lateral kondensasyon
yöntemi kullanılarak dolduruldu. Diğer dişlerin kök kanalları doldurulmadı. Kontol grubundaki (n=14) dişlere hiç bir işlem uygulanmadı.
Örnekler içerisi akrilik rezin dolu bakır anolara yerleştirildikten sonra, universal test cihazı ile kökler kırılana kadar vertikal kuvvet
uygulandı. Elde edilen veriler tek yönlü varyans analizi ve Bonferroni düzeltmeli PostHoc testleri kullanılarak analiz edildi. Kontrol
grubunun kırılma direnci diğer tüm gruplara göre daha yüksek bulundu (p<0.05). Deney gruplarında (sadece prepare edilen), RaCe grubu
ProTaper grubundan daha yüksek kırılma direncine sahipti (p<0.05). Buna karşın, K3 grubu ile diğer deney grupları (ProTaper, RaCe)
arasında bir farklılık gözlenmedi (p>0.05). Kök kanal dolgulu deney grupları arasında bir farklılık bulunmadı (p>0.05). Döner kök kanal
aletleri dişleri önemli derecede zayıflatmaktadır, bununla birlikte kanalları Epiphany/Resilon ile doldurmak bu direnç kaybını kısmen tolere
etmektedir.
The aim of this study was to compare the effects of three different rotary NiTi instruments (K3, RaCe, ProTaper) and a resin-based root canal filling (Epiphany/Resilon) on fracture resistance of endodontically treated roots. Ninety eight freshly extracted human mandibular premolar teeth roots were divided randomly into three experimental groups (n=28) and a control group (n=14). Teeth were sectioned at the cemento-enamel junction with a multipurpose bur. Root canals were instrumented with either K3 (K3 Group), RaCe (RaCe Group), or ProTaper (ProTaper Group) rotary instruments in experimental groups. Fourteen roots from each group were then filled with lateral condensation technique using Epiphany/Resilon root canal filling. Other ones were left unfilled. Controls (n=14, intact tooth) received no treatment. Specimens were then mounted in copper rings, were filled with a self-curing polymethylmethacrylate resin, and the force required to cause vertical root fracture was measured using a universal testing device. Fracture force of the roots was recorded and the results in the various groups were compared. Data was analyzed statistically using one way variance analysis and Post Hoc with the Bonferroni correction tests. Control group was significantly stronger than all groups with instrumented and filled roots (p<0.05). Among the instrumented groups, RaCe group was significantly stronger than ProTaper group (p<0.05). Whereas, the K3 instruments, produced a similar amount of fracture resistance in the canal walls compared with the other instruments (ProTaper, RaCe). There was no significance among the filled groups (p>0.05). It was concluded that rotary NiTi instruments significantly weakened the teeth, however, filling the canals with Epiphany/Resilon partially tolerated this weakening.
