Abstract

In vitro comparison of Canal working length determination with NaOCl of three different apex locators. The aim of this in vitro study is the compare and determine the success of three different modern electronic apex locators. In this study 36 undecayed upper central teeth have been used. To have a certain reference the teeth have been cut from the cemento enamel junction limit. Easy access has been achieved by using gates-glidden drills to the files of 1\3 of the coronal root canals. Each teeth length has been measured by using #15 K-File X8 magnified stereomicroscope pushing forward until the tip is visible from the apical foramen. The measurements have been repeated three times and the mean for each tooth has been recorded as actual lengths AL . Later the teeth have been embeded to the alginate placed in plastic boxes and are measured with %5.25 NaOCl in the root canals via #15 K-File electronic apex locators. The mean of the measurements has been taken after repeating them thrice. They are recorded as RU, PU and I2U. All values measured from each electronic apex locator have been compared with the results and actual lengths. The statistical analysis has been made with Sample paired t test. The relevance between the parameters is determined as p

Abstract

Bu in vitro çalışmanın amacı, üç farklı gelişmiş elektronik apeks bulucunun kanal çalışma boyunu tesbitinde ki başarısını belirlemek ve birbirleriyle karşılaştırmaktır.Çalışmamızda kök oluşumunu tamamlamış rezorpsiyon bulunmayan, çürüksüz 36 adet üst santral diş kullanılmıştır. Belirli bir referans olması için dişler mine sement sınırından kesilmiştir. Kök kanallarının 1/3 lük kısmında Gates glidden frezler kullanılarak eğelere rahat bir giriş sağlanmıştır. Her dişin uzunluğu #15 nolu K-file kullanılarak X8 büyütmeli stereomikroskop altında eğenin ucu apikal foramenden görülünceye kadar ilerletilerek ölçülmüştür. Ölçümler üç kere tekrarlanmış ve ortalamalar her diş için gerçek uzunluk olarak kaydedilmiştir. Sonra dişler aljinat modele gömülmüş ve elektronik apeks bulucular ile ölçümler yapılmıştır. Bu ölçümler de 3 kez tekrarlanarak ortalaması alınmıştır. Ortalamalar Root ZX Mini uzunluğu RU , Propex Pixi uzunluğu PU , Ipex II uzunluğu I2U olarak kaydedilmiştir. Her elektronik apeks bulucularla ölçülen değerler birbirleriyle ve gerçek uzunluklar ile karşılaştırılmıştır. İstatistiksel analizler Sample Paired t testi kullanılarak yapılmıştır. Parametreler arasındaki anlamlılık düzeyi p
