CBCT-based bone quality assessment in decompression of large odontogenic cystic lesions

Objectives Bone quality comprises bone mineral density and trabecular microstructure. The aim of this study was to explore the effectiveness of cone-beam computed tomography (CBCT) in evaluating bone quality of large odontogenic cystic lesions after decompression using CBCT and BoneJ software, and to determine whether secondary definitive surgery can be guided using CBCT data. Methods Twenty-seven patients with large odontogenic cystic lesions treated by decompression were evaluated by CBCT. Medical history and perioperative details were analyzed. Results The Δ CT values for all patients with cystic lesions decreased after decompression, with no differences for age, sex, and histology ( p > 0.05). Bone volume fraction and trabecular number of new cancellous bone (0.012
