Efficacy of Different Retreatment Techniques in Molar Root Canals: An ex vivo Study

Abstract

The aim of this study was to evaluate the efficacy of two different rotary instruments with and without a solvent versus hand files in the removal of gutta-percha root fillings. Sixty extracted human molar teeth were used for this study. Mesiobuccal canals of teeth were prepared and filled with sealer and guttapercha. Before retreatment was applied, radiographs were taken. Specimens were divided into six groups: Group 1:Protaper Universal Rotary Retreatment System, Group 2: Protaper Universal Rotary Retreatment System with eucalyptol , Group 3: Profile, Group 4: Profile with eucalyptol, Group 5: Hedström files Group 6: Hedström files with eucalyptol. During retreatment procedure, the operating time was recorded. After removing root canal fillings from the canals, radiographs were taken, digitalized and analyzed in a software for image analysis. The ratio of remaining obturation material to root canal surface was derived. In this study gutta-percha and sealer remnants were present within the root canal in all test groups. Statistical analysis showed that there was no significant difference between the techniques P>0.05 ; however, a significant statistical difference P

Molar kök kanallarında farklı kanal tedavisi yenileme tekniklerinin etkinliği: ex vivo çalışma

Abstract

Bu çalışmanın amacı iki farklı döner aletin ve el aletlerinin çözücülü ve çözücüsüz kullanılarak gütaperka kök kanal dolgusunun uzaklaştırılmasında etkinliklerinin belirlenmesidir. kanal dolguları uzaklaştırıldıktan sonra radyografiler alınmış, dijital ortama aktarılmış ve görüntüler bir yazılım programında analiz edilmiştir. Kök kanal yüzeyindeki dolgu materyali kalıntılarının oranı değerlendirilmiştir. Bu çalışmada tüm test gruplarındaki kök kanallarında gütaperka ve kanal patı kalıntıları mevcuttur. İstatistiksel analiz teknikler arasında anlamlı bir fark olmadığını göstermiştir P>0.05 , bununla birlikte kanal dolgusunun boşaltılma süresi açısından gruplar arasında anlamlı farklar P
