Abstract

The aim of this study was to compare the Ktype hand instruments which made of various alloys Ni-Ti ,Ti-Al, stainless-steel and flexible stainless-steel in shaping severely curved root canals and simulated canals. 80 resin block and 80 extracted mandibular molar teeth were used in this study.The degree of canal curve in the resin blocks was 42, and in the teeth 21-49.The teeth and the resin blocks were randomly divided into 4 groups of each containing 20 teeth. The root canals were prepared up to 40 K-type instrument using step-back tecnique. The photograph of resin block were taken before and after preparation. The photographs of the radiographs were taken before and after preparation in the teeth group.The images of the canals were drawn and compared on acetate paper.The efficiency of the files in terms of prevalence of canal abberrations and fracture of the root canal instruments were detected. Enlargement amounts at inner and outer sides,and the measurements of the enlargement sides at three levels were calculated. According to the results of this study, canal aberrations were signifiantly greatest in stainlesssteel files and lowest in Ni-Ti files.Stainless-steel and flexible stainless-steel files removed signifiantly greater amount of material than Ni-Ti and Ti-Al files. Comparison of the preparations revealed that stainless-steel files changed the curvature of the canals extremely whereas flexible stainlesssteel files changed moderately. Ni-Ti and Ti-Al fies protected the curvature but the canal enlargements of Ti-Al files were not enough.

Abstract

Çalışmamızda, Ni-Ti, Ti-Al, E.P.Ç esnek paslanmaz çelik ve P.Ç paslanmaz çelik alaşımlarını içeren K-Tipi kök kanal aletlerinin eğri kanallı çekilmiş alt büyük azı dişlerinde ve suni kanallarda oluşturdukları preparasyonların karşılaştırılması amaçlanmıştır. Araştırmamızda 80 adet çekilmiş alt büyük azı dişi ve 80 adet suni kanal kullanılmıştır.Suni kanallarda eğim açısı 42 derece,dişlerde ise 21-49 derece olarak seçilmiştir. Daha sonra dişler ve suni kanallar 20’şer örnek içeren 4 gruba ayrılmıştır. Kök kanalları step-back teknği kullanılarak 40 nolu K tipi eğeye kadar prepare edilmiştir.Preparasyon öncesi ve sonrası suni kanalların resmi çekilmiştir.Çekilmiş dişlerde ise preparasyon öncesi ve sonrası alınan radyografilerin fotoğrafları ele edilmiştir. Dişlerin ve suni kanalların preparasyon öncesi ve sonrası görüntüleri asetat kağıdı üzerine çizilip görüntüler birbirleri ile çakıştırılmıştır. Kullanılan eğelerin kanal içerisinde komplikasyon oluşturma yüzdesi incelenmiş olup eğimin iç ve dış tarafında yapılan genişletmenin miktarı koronal, orta ve apikal bölgelerde hesaplanıp, preparasyon yönleri değerlendirilmiştir. Çalışmanın sonuçlarına göre preparasyona bağlı komplikasyonlar en fazla P.Ç eğelerde, en az Ni-Ti eğelerde gözlenirken,Ti-Al ve E.P.Ç.eğelerde sonuçların değişkenlik gösterdiği tespit edilmiştir.Kanallardan kaldırılan madde miktarı incelendiğinde E.P.Ç ve P.Ç eğeler Ni-Ti, Ti-Al eğelere kıyasla belirgin biçimde daha fazla miktarda madde kaldırmıştır. P.Ç eğelerin kanal kurvatüründe şiddetli sapmaya sebep olduğu gözlenirken E.P.Ç kanal eğelerinde orta derecede bir sapma gözlenmiştir. Ni-Ti grubu eğeler kanal formunu takip eden bir preparasyon oluştururken.Ti-Al grubu yetersiz bir preparasyon oluşturmuştur
