Assessment of Radiation Dose Received by Thyroid Gland during OPG Examinations

Abstract

This study was conducted to assess the thyroid gland dose for the patients during Roth pan tomography (OPG) examination , The data were collected within one month from August 2015 to September 2015 in Khartoum dental hospital , only adult patients ≥18 years were involved in the study, All pregnant and infant patients were excluded from the study. A dental panoramic Planmeca/Proline XC machine was used in our study. The aim of the study carried out. to measure patient dose. And to know the relation between the ESD of the thyroid and Kvp, Mas, age, BMI. The result related that there is direct relationship between thyroid dose and Kvp and mAs , every increase in the Kvp or the mAs will increase the ESD to the gland also thyroid gland dose with BMI of patient will increase the ESD with every increase in the unit of the BMI . The mean ± standard deviation of ESD calculated was (3.397±0.4139).
