Comparison between effective doses of different imaging modalities applied in Orthodontics using Anthropomorphic Phantom

Abstract

The use of CBCT in orthodontics has been revolutionary as it provides necessary information for diagnosis and treatment planning. Many concerns are related to the increased risk of exposure resulting from 3D imaging as opposed to 2D imaging in orthodontics.

The aim of our study was to compare between effective doses of different imaging modalities applied in orthodontics.

The CS9300 CBCT machine was used for the CBCT exposures using different scanning protocols and parameters for the adult and child, and the hybrid 2D/3D Orthophos SL machine was used for the panoramic radiography and lateral cephalometry. We used two anthropomorphic phantoms in this study: an adult male phantom and a child phantom. Optically stimulated luminescent dosimeters were used for measurements.
