Evaluation of a Low-dose exposure CBCT protocol for post-graft evaluation of treatment of cleft patients
The patient underwent two CBCT examinations (Accuitomo 170; J Morita Corp., Kyoto, Japan): one examination followed the clinical standard-dose protocol (exposure settings: 90 kV, 5 mA, and 9.4 s), and one, the low-dose protocol (90 kV, 2 mA, 9.4 s). The field of view (FOV) was 6.0 cm x 6.0 cm, the rotation mode was 180 degrees, and voxel size was 0.125 mm. Volume was reconstructed in slices of 1-mm thickness and interval. The dose area products (DAP) were 423 mGy cm2 for the clinical, standard-dose protocol and 172 mGy cm2 for the low-dose protocol.
The aim was to establish if a low-dose protocol could provide diagnostically acceptable image quality for assessing bone healing after alveolar bone grafting.
