Evaluation of The Relationship Between Radiation Doses And Image Quality of CBCT Images Obtained In Different Voxels For Implant Planning

Abstract

Objective: To investigate the effect of different imaging modes and voxel sizes on linear measurement accuracy and organ radiation doses in cone-beam computed tomography (CBCT) for dental implant planning. Materials and Methods: Four dry skull specimens (2 maxillae, 2 mandibles) with gutta-percha reference markers at specific anatomical sites were scanned. Soft-tissue simulation was performed using three layers of wax (mean thickness: 4.5 mm). CBCT scans were performed using a Newtom 7G device in three modes: low-dose, regular-dose, and best-quality. Initial measurements between reference points were recorded using a digital caliper. Subsequently, an experienced oral radiologist performed measurements on CBCT images reconstructed at different voxel sizes. Organ doses were calculated using PCXMC 2.0 Rotation software based on dose-area product values. Results: High agreement was observed between caliper measurements and all CBCT protocols (p<0.05). However, significant differences in organ doses were noted across imaging modes. Effective dose values ranged from 17.4 µSv to 135.7 µSv for mandibular scans and from 24.0 µSv to 181.9 µSv for maxillary scans according to ICRP 103, representing an approximately 8-fold increase from low-dose to high-dose protocols. Conclusion: Low dose CBCT protocols provided sufficient accuracy for implant planning while substantially reducing radiation exposure. Given the stochastic nature of radiation effects, low-dose imaging is recommended when linear measurements are the primary diagnostic requirement.
