Objectives: To assess the effect of glide path on the amount of apically extruded debris after instrumentation with WaveOne and OneShape. Materials & Methods: Forty-eight extracted human mandibular incisors were assigned to 4 groups. In groups 1 and 2, preparation was completed with WaveOne, in groups 3 and 4 canals were prepared with OneShape. Before instrumentation, in groups 1 and 3, glide path was created with PathFile 1, 2, and 3 at working length, whereas in groups  2 and 4, glide path was not performed. The weight of the extruded debris for each group was calculated by comparing the pre-  . . .;and post-instrumentation weights of the eppendorf tubes. The time required for reaching full WL was also recorded. Data were analysed by Kruskal–Wallis and Mann–Whitney U tests. Results: There was no difference in the amount of debris extruded between the single file systems (P=0.234). Time required to reach full WL was significantly decreased by creating a glide path (P< 0.05). Conclusions: Creation of a glide path does not significantly affect the apically extruded debris.

Bu çalışmanın amacı iki farklı apeks bulucu cihazınfarklı preparasyon çaplarındaki doğruluğunun karşılaştırılmasıdır.GEREÇ VEYÖNTEM: Bu çalışma için çekilmiş 14 adet insanalt keser dişi kullanıldı. Dişlerin kronları mine-sement birleşiminden kesilerek uzaklaştırıldı. Kök kanalı içerisinde10 numaralı bir K-tipi eğe apikalden görülünceye kadarilerletildi ve elde edilen boy bir kumpas yardımıyla ölçüldü. Gerçek çalışma boyu için bu ölçümden 0.5 mm çıkarıldı ve kaydedildi. Dişler periodonsiyumu taklit etmekamacıyla aljinat içerisine gömüldü. Propex II ve Root ZXmini elektronik apeks bulucu cihaz ile ilk ölçümler (preparasyon öncesi) yap . . .ıldı ve kaydedildi. Daha sonra dişlerProTaper döner eğe sistemi ile F1 çapına kadar genişletildi. Elektonik apeks bulucu cihazlar ile tekrar ölçüm yapıldı. Son olarak kök kanalları F3 çapına kadar genişletildive çalışma boyları cihazlar ile bir kez daha ölçüldü. Eldeedilen bütün apeks bulucu cihaz verilerinin gerçek boylarla olan farkları hesaplandı. Gerçek boy ile preparasyonöncesi değerler ve sonrası değerler farkları hem elektronikapeks bulucu cihazlar için kendi içerinde ve hem de birbirleriyle t-testi kullanılarak istatistiksel olarak karşılaştırıldı.BULGULAR: Preparasyon öncesi ve diğer iki preparasyonçaplarında, Propex II ve Root ZX Mini elektronik apeks bulucu cihazlar arasında ve kendi içlerinde istatistiksel olarakanlamlı bir fark görülmedi (p>0.01).SONUÇ: Propex II ve Root ZX mini elektronik apeks bulucucihazların kök kanal tedavisi başlangıcında ve farklı preparasyon çaplarında birbirleri ile uyumlu sonuçlar verdiğigörüldü. The aim of this study was to compare the accuracy of two electronic apex locator devices after root canalpreparation at different sizes.MATERIALS ANDMETHOD: Fourteen extracted mandibular incisors were used in this study. Crowns were removed atthe cementoenamel junction. The actual canal length wasdetermined by introducing a size 10 K-file into the canaluntil the file tip became visible at the apical foramen andthen subtracting 0.5 mm from the measured length. Theteeth were embedded in alginate model. Initial (pre-operative) root canal length measurements were performed byusing Propex II and Root ZX mini electronic apex locators.Then, the root canals were prepared by using ProTaper rotary system to size F1. Working lengths were measuredagain by using the two electronic apex locators. Finally,the root canals were prepared to size F3 and the workinglengths were measured once more by using the same devices. Differences between the actual working length values and the electronic apex locator values (initial valuesand values obtained after F1 and F3 preparation sizes)were calculated and compared statistically using t-test.Comparisons were done both between the two devicesand within each device.RESULTS: No statisticall significant difference was foundbetween and within the readings of the Propex II and RootZX mini electronic apex locator devices for measurementsperformed at the different stages (p>0.01)CONCLUSION: Propex II and Root ZX Mini electronic apex locator devices exhibited comparable results at the beginning of the root canal treatment and at differentpreparation size Daha fazlası Daha az
