Abstract
AIM OF THE STUDY: To determine and compare the canal transportation and centering ability of ProTaper Universal, Hyflex EDM and WaveOne GOLD using Micro computed tomography. METHODOLOGY: Sixty mesiobuccal canals of mandibular molars were selected and randomly divided into three groups of 20 samples each: ProTaper Universal (group one), Hyflex EDM (group two) and WaveOne GOLD (group three). Pre- and postinstrumentation scanning of samples were done using micro-CT. scanned images were three dimensionally reconstructed, these three dimensional images from root cross-sections at 3mm, 6mm and 9mm from the apex were accessed to determine canal transportation and centering ability. SPSS software was used for statistical analysis. The significance level was set at p =0.05. RESULTS: ProTaper Universal files showed highest transportation and less centered when compared to Hyflex EDM and WaveOne GOLD files. No significant difference was found between Hyflex EDM and WaveOne GOLD instruments. CONCLUSION: Hyflex EDM and WaveOne GOLD files shaped curved root canals without significant canal transportation and better centered when compared to ProTaper Universal files.
