Comparative evaluation of the remaining dentin thickness using different root canal retreatment techniques: A cone-beam computed tomography study
This study was to evaluate the best technique to preserve radicular dentin after performing different retreatment procedures. Twenty maxillary central incisors were cleaned and shaped with the ProTaper Next and later obturated. The dentinal thickness were then measured from the axial views in the sc...

Twenty maxillary central incisors were cleaned and shaped with the ProTaper Next and later obturated. The dentinal thickness were then measured from the axial views in the scanned CBCT images at 0mm, 5mm, 10mm and 13mm from the root apex. The teeth were then randomly placed into four groups and different systems were employed to remove the gutta percha. These were Hedstrom file without and with xylene (Groups 1 & 2) and ProTaper Universal Retreatment files without and with xylene (Groups 3 & 4). The dentin thicknesses dimensions were then measured again on subsequent CBCT scanned axial views. Group 1 showed significant difference in the pre and post retreatment dentinal thickness at 0 and 5 mm (p< 0.05). Group 2 and 4, which were the groups with xylene showed significant difference in the dentinal thickness at 5 and 13 mm. Interestingly, Group 3 showed significant difference only at 0 mm. In conclusion, H-files and Protaper Universal Retreatment files (with or without xylene) were effective in the removal of the obturating material.
