| Popis: | Objectives: The present study was conducted to propose up a technique for evaluation of OITRR in bicuspids as evaluated by con-beam computed tomography (CBCT) and micro computed tomography Micro CT). Methods: Ten healthy maxillary first premolars were extracted from eight adolescent healthy patients. Five of the premolars were removed prior to application of any orthodontic forces (group 1 control group), and the other five premolars were indicated to be removed in non– extraction orthodontic treated cases after a year due to change in their treatment plan to extraction of these five premolars (group 2 treatment group). All patients had initial CBCT as part of their initial treatment records and all extracted teeth were scanned using a micro-computed tomography (Micro CT) scanner. Reconstructed scanned images were processed and numerous crucial resorption lacunae parameters were evaluated including linear measurements of the width and length of the resorption lacunae. Comparisons were performed between the two groups initial teeth lengths (measured from CBCT and MicroCT). Results: Orthodontic treatment caused the formation of considerably large tooth root resorption lacunae measured in length and breadth along the length of the root that were extracted after been moved orthodontically compared to those who were not moved orthodontically (P |
