OBJECTIVE: The aim of this study was to compare the effect of nickel-titanium file systems with different taper angles working with rotation and reciprocation motion on the amount of debris extruding apically.
MATERIALS AND METHOD: The study was performed using the Myers and Montgomery model. Forty-five human maxillary anterior teeth were inserted into preweighed Eppendorf tubes and randomly classified into three groups. After manual glide-path preparation, the teeth in each group were instrumented to the working length set 1 mm short of the anatomical apex using the standard sequence provided by the manufacturers: Group 1: Reciproc Blue (Easy In Smile, New Jersey, USA), Group 2: T-endo must (Dentac, İstanbul, Turkey),Group 3: T-endo mis (Dentac, İstanbul, Turkey). Root canals were irrigated with 10 mL 2.5% NaOCl, 17% EDTA, and distilled water between each file insertion. The tubes with collected debris were stored in an incubator at 70°C for 7 days. Measurement of the weight of extruded debris was performed by subtracting the pre-instrumentation from the post-instrumentation weight of the tubes. Data were analyzed using one-way ANOVA and Tukey’s Honest Significant Difference Test (α=0.05).
RESULTS: The weights of the apically extruded debris were 0.0094±0.0015 g in Group 1, 0.0075±0.0012 g in Group 2, and 0.0044±0.0010 g in Group 3, and the difference between all groups was statistically significant (p<0.05).
CONCLUSION: The amount of apically extruded debris is related to the taper angle of the file used and the kinematics of the file.

Öz

Amaç: Bu çalışmanın amacı, rotasyon ve resiprokasyon hareketi ile çalışan farklı koniklik açılarına sahip nikel titanium eğe sistemlerinin apikalden taşan debris miktarına etkisini karşılaştırmaktır.
Gereç ve Yöntem: Çalışma Myers ve Montgomery modeli kullanılarak yapıldı. Kırk beş insan üst kesici diş önceden tartılmış Eppendorf tüplerine yerleştirildi ve anatomik apeksten 1 mm kısa çalışma boyu olacak şekilde Grup 1: Reciproc Blue (Easy In Smile, New Jersey, ABD); Grup 2: T-endo must (Dentac, İstanbul, Türkiye), Grup 3: T-endo mis (Dentac, İstanbul, Türkiye) ile şekillendirildi. Kök kanalları 10 mL %2.5 NaOCl, %17 EDTA ve distile su ile irrige edildi. İçerisinde debris olan tüpler 7 gün boyunca 70 °C inkübatörde bekletildi. Tüplerin son ağırlığından ilk ağırlıkları çıkarılarak apikalden taşan debris miktarları elde edildi. Veriler, tek yönlü ANOVA ve Tukey çoklu karşılaştırma testi ile değerlendirildi (α=0,05).
Bulgular: Grup 1'de 0.0094±0.0015 g, Grup 2'de 0.007±0.0012 g ve Grup 3'te 0.0044±0.0010 g debris görüldü. Tüm gruplar arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.05).
Sonuç: Apikalden taşan debris miktarı, kullanılan eğenin koniklik açısı ve eğenin kinematiği ile ilgilidir.
