Aim: The objective of this study was to compare the resistance to cyclic fatigue of One Curve (OC), 2Shape (TS), and Reciproc (RC) files by considering the operator’s experience. Materials and methods: Mesial root canals of ninety mandibular molar teeth were prepared by three endodontic residents during the first 6 months of their training (IE) or by three professionals with min. 5 years of endodontic training at postgraduate level (E). Then, 45 files used by the inexperienced group (IE-OC, IE-TS, and IE-RC), 45 files used by the experienced group (E-OC, E-TS, and E-RC), and new 45 files (control group; C-OC, C-TS, and C-RC) were rotated in simulated canals until separation failure occurred. (n=15) The time to fracture was calculated. For statistical analysis, ANOVA and Tukey’s post hoc tests were used (P<0.05). Results: When compared to the experienced and inexperienced groups, the time-to-fracture of control group files was found to be significantly higher (P<0.05). Comparing the experienced and inexperienced operator groups, no significant difference was found for RC files, whereas significant differences were determined for TS and OC files (P<0.05). Conclusions: The residual fatigue life of TS and OC instruments may be decreased by inexperienced operators more than experienced operators. Single file RC instrument was, however, not affected by the operator’s experience. Keywords: Cyclic fatigue, experienced operator, Reciproc, OneCurve, 2Shape, Operatör deneyiminin One Curve, 2Shape ve Reciproc eğe sistemlerinin döngüsel yorgunluk direncine etkisi ÖZ Amaç: Bu çalışmanın amacı, operatör deneyimini dikkate alarak One Curve (OC; Micro-Mega, Besancon, Cedex, Fransa), 2Shape (TS; Micro-Mega) ve Reciproc (RC; VDW, Münih, Almanya) eğelerin döngüsel yorulma direnclerini karşılaştırmaktır. Gereç ve Yöntem: Doksan mandibular molar dişin mezial kök kanalları, eğitimlerinin ilk 6 ayındaki üç endodonti uzmanlık öğrencisi (IE) tarafından veya doktora düzeyinde min. 5 yıllık endodontik eğitim almış üç uzman (E) tarafından prepare edildi. Ardından, deneyimsiz grup tarafından kullanılan 45 eğe (IE-OC, IE-TS ve IE-RC), deneyimli grup tarafından kullanılan 45 eğe (E-OC, E-TS ve E-RC) ve yeni 45 eğe (kontrol grubu; C-OC, C-TS ve C-RC) kırık oluşana kadar simüle edilmiş kanallarda döndürüldü. (n = 15) Eğelerin kırılma süreleri hesaplandı. ANOVA ve Tukey’s post hoc testleri istatistiksel analiz için kullanıldı (P <0.05). Bulgular: Kontrol grubundaki eğe sistemlerinin kırılma zamanı deneyimli ve deneyimsiz grubunkine göre anlamlı derece daha yüksek bulunmuştur (P<.05). Deneyimli ve deneyimsiz operatörlerin grupları karşılaştırıldığında RC eğeleri için anlamlı fark bulunmamışken, TS ve OC eğeleri için anlamlı fark bulunmuştur (P<.05). Sonuç: Bu çalışmada, TS ve OC eğelerin rezidüel yaşam ömrü deneyimli operatörlere kıyasla deneyimsiz operatörlerde daha fazla azaltılmıştır. Tek eğe RC sistemler ise operatörün deneyiminden etkilenmemiştir. Anahtar Kelimeler: Döngüsel yorgunluk, deneyimli operatör, Reciproc, OneCurve, 2Shape,
