Popis: Compare canal transportation and dentin removal using micro computed tomography (micro-CT) and measure instrumentation time in the root canal preparation of primary molars using K-files, ProDesign Logic and Reciproc files.A representative sample of 81 root canals of primary molars was randomised into three groups: K-files (#15-40), ProDesign Logic (#25) and Reciproc (R25). A single-trained operator prepared all root canals. A standardised micro-CT evaluation was performed before and after instrumentation using the CTanReciproc led to more canal transportation than K-files and ProDesign Logic (p 0.001) in middle third, whereas K-files led to the most canal transportation in the apical third (p = 0.017). ProDesign Logic and Reciproc removed less dentin on the opposite side of the root curvature in the apical third compared to K-files (p = 0.008). Instrumentation time was better with ProDesign Logic and Reciproc than K-files (p 0.001).ProDesign Logic demonstrated good results with regard to canal transportation and required less instrumentation time in primary molars. Reciproc and K-files led to the most canal transportation in the middle and apical third, respectively.
