Objective: The aim of this study was to compare the accuracy of a newly developed multi-frequency electronic apex locator iPex II with three different multi-frequency electronic apex locators in teeth with different sizes of apical foramina.

Materials and Method: Twenty-six extracted mandibular premolars were used in this study. The teeth were decoronated, and the root canals were coronally flared. Actual working length was determined by inserting a #15 K-file until the tip was visualized just within apical foramen. Actual working length was established 0.5 mm short of the distance between the rubber stopper and the file tip. Using Protaper F1, F2 and F3 files (Dentsply Maillefer), over-instrumentation 1 mm beyond the apical foramen was done. The teeth were embedded in teflon molds with alginate exposing the coronal 5 mm. Electronic working length measurements were done by using Raypex 5 (VDW), Raypex 6 (VDW), iPex (NSK Inc.) and iPex II (NSK Inc.) electronic apex locators. Differences between the electronic and actual working lengths were calculated. One-way analysis of variance (ANOVA) was used for the statistical analysis of the accuracies of the electronic apex locators (α=0.05).

Results: Inter-group comparisons revealed that there was no statistically significant difference between the accuracies of the different electronic apex locators (p>0.05). Intra-group comparisons also revealed that there was no statistically significant difference between different apical foramen sizes (p>0.05).

Conclusion: iPex II and the other electronic apex locators provided similar endodontic working length measurements in teeth with enlarged apical foramina. All electronic apex locators tested in this study were found clinically acceptable for working length determination.

Amaç: Bu çalışmanın amacı, farklı çaplarda apikal foramenlere sahip dişlerde yeni geliştirilmiş multi-frekans elektronik apeks bulucu iPex II ile üç farklı multi-frekans elektronik apeks bulucunun doğruluğunun karşılaştırılmasıdır.

Gereç ve Yöntem: Çalışmada 26 adet çekilmiş alt çene küçük azı dişi kullanıldı. Dişlerin kronlarının uzaklaştırılmasından sonra kök kanalları koronal olarak genişletildi. Gerçek çalışma boyu tespiti, #15 K-tipi eğenin ucu apikal foramende görünür hale gelene kadar ilerletilerek yapıldı. Gerçek çalışma boyu, lastik stoper ve eğe arasındaki uzunluktan 0.5 mm kısa olarak kabul edildi. ProTaper F1, F2 ve F3 (Dentsply Maillefer) eğeler ile apikal açıklıktan 1 mm ilerde taşkın preparasyonlar yapıldı. Dişler, koronal 5 mm’leri açıkta kalacak şekilde aljinat ile teflon kalıplara gömüldü. Raypex 5 (VDW), Raypex 6 (VDW), iPex (NSK Inc.) ve iPex II (NSK Inc.) elektronik apeks bulucular kullanılarak elektronik çalışma boyu ölçümleri yapıldı. Elektronik ve gerçek çalışma boyları arasındaki farklar hesaplandı. Elektronik apeks bulucuların doğruluklarının istatistiksel değerlendirmesinde tek yönlü varyans analizi (ANOVA) kullanıldı (α=0.05).

Bulgular: Gruplar-arası karşılaştırmada, elektronik apeks bulucuların doğrulukları arasında istatistiksel olarak anlamlı farklılık görülmedi (p>0.05). Grup-içi karşılaştırmada, farklı apikal foramen çaplarına göre elektronik apeks bulucuların doğrulukları arasında yine istatistiksel olarak anlamlı farklılık görülmedi (p>0.05).

Sonuç: Apikal foramenleri genişletilmiş dişlerde, iPex II ve diğer elektronik apeks bulucuların çalışma boyu ölçümleri arasında farklılık olmadığı görüldü. Kullanılan tüm elektronik apeks bulucuların çalışma boyu ölçümlerinin klinik olarak kabul edilebilir olduğu bulundu.
