TI  - The retreatment abilities of ProTaper Next and F6 Skytaper: a micro-computed tomography study
AB  - PurposeThe aim of this study was to evaluate the retreatment abilities of the ProTaper Next(PTN) and F6 SkyTaper (F6) systems by using micro-computed tomography (microct),radiographic and microscopic imaging techniques.Materials and MethodsThe root canals of twenty-six extracted mandibular premolar teeth were preparedand obturated. For the retreatment procedure, the teeth were randomly divided intotwo equal groups according to endodontic instruments: PTN (X4) and F6 (#40/.06).Pre- and post-operative filling material volumes were measured with micro-ct, andareas were measured with radiographic and microscopic imaging techniques. Thepercentages of residual material were calculated, and then statistically compared.The significance level was set at p<0.05.ResultsThere was no statistically significant difference between F6 and PTN for retreatmentefficacy in the micro-ct and radiographic imaging techniques (p>0.05). PTNdemonstrated better cleaning ability when evaluated by microscopic imaging.(p<0.05). The correlation was moderate between micro-ct and radiographic,and micro-ct and microscopic imaging groups; however, it was strong betweenradiographic and microscopic imaging methods.ConclusionThe PTN and F6 files had similar effects in the removal of filling material with microctevaluation. The radiographic imaging method gave similar results with micro-ctimaging.
