To characterize effective dose distributions in the craniofacial area for different acquisition parameters
of dental cone beam CT, thermoluminescent dosimeters (TLD) were placed within an anthropomorphic phantom for measuring effective dose. Results showed higher effective doses with 8 mA compared to 3 mA. The relative high effective dose distribution was concentrated around the field of view (FOV) but extended beyond it, irradiating nearby tissues. Understanding these effective dose distributions can aid in optimizing patient safety in dental radiology practices.
