Objective: In this study, three NiTi systems were compared in terms of the changes in canal curvature in both mesiodistal (MD) and buccolingual (BL) directions by cone-beam computed tomographic (CBCT) imaging. Methods: Mesiobuccal canals of 48 extracted human mandibular molar teeth with severely curved roots (32°-52°) were used. The teeth were randomly divided into three groups as follows; group1: WaveOne primary, group 2: OneShape, and group 3: ProTaper Next. The canals were instrumented to a master apical file size of #25 in each group. Preinstrumentation root canal curvatures were obtained by using CBCT images. The root canal curvature of each tooth was recorded. After the instrumentation, postinstrumentation CBCT images were obtained with the same method. Pre-and-postinstrumentation CBCT images were analyzed by using ImageJ software. Differences among the groups were analyzed by one way analysis of variance (ANOVA) or the Kruskal–Wallis test. Results: No difference was found among three instrumentation systems (p>0.05). Conclusion: Although all instruments demonstrated changes in root canal curvatures and straightened the root canals, these changes and straightenings may be inconsiderable in clinical conditions. Keywords: CBCT imaging, severely curved canal, root canal straightening, NiTi instruments.

Amaç: Bu çal??mada, konik ???nl? bilgisayarl? tomografi (CBCT) kullan?larak üç farkl? NiTi e?e sistemi meziodistal (MD) ve Bukkolingual (BL) yönde kanal e?imlerindeki de?i?iklikler aç?s?ndan kar??la?t?r?lm??t?r. Yöntem: A??r? e?imli (32°-52°), 48 adet çekilmi? insan alt çene büyük az? di?inin mesiobukkal kanallar? kullan?ld?. Di?ler, grup 1: WaveOne primary, grup 2: OneShape, grup 3: ProTaper Next olarak rastgele üç gruba ayr?ld?. Kanallar her grupta master apikal e?enin #25 olacak ?ekilde ?ekillendirildi. ?ekillendirme öncesi kök kanal e?imleri CBCT görüntüleri kullan?larak elde edildi. Her di?e ait e?imler kaydedildi. Ayn? yöntem kullan?larak ?ekillendirme sonras? CBCT görüntüleri elde edildi. ??lem öncesi ve sonras? CBCT görüntüleri, ImageJ software program? kullan?larak analizleri yap?ld?. Gruplar aras? farkl?l?k ANOVA ya da Kruskal–Wallis testi kullan?larak analiz edildi. Bulgular: Üç ?ekillendirme sistemi aras?nda herhangi bir fark bulunmam??t?r (p>0,05). Sonuç: Tüm e?e sistemleri kök kanallar?n?n e?iminde de?i?ikli?e ve düzle?tirmeye neden olmas?na ra?men, bu de?i?iklikler ve düzle?meler klinik ?artlarda kayda de?er nitelikte olmayabilir. Anahtar Kelimeler: CBCT görüntüleme, A??r? e?imli kanal, Kök kanal düzle?mesi, NiTi e?eler.
