Evaluation of Local Diagnostic Reference Levels (DRLs) for Panoramic X-Ray Examinations in Ambulatory Healthcare Services (AHS) Dental Clinics in Abu Dhabi, UAE

Abstract

Background: Panoramic radiography, a widely used imaging technique in dental settings, offers a comprehensive view of the maxillofacial region.  However, ionizing radiation in dental radiography raises significant concerns about patient safety, particularly in the pediatric population, due to their higher radiosensitivity [1]. In recognition of our shared responsibility, this study aimed to establish local diagnostic reference levels (DRLs) that consider the specific patient population and clinical practices within a given healthcare system, ensuring the safe and responsible use of panoramic X-ray examinations. The study specifically looked at the radiation doses patients received during panoramic X-ray exams at Ambulatory Healthcare Services (AHS) dental clinics in Abu Dhabi, UAE, and the levels of optimization that accompanied them. Methods: This collaborative study evaluated the diagnostic reference values for pediatric and adult patients undergoing panoramic dental examinations. The dose area product (DAP) data were collected for actual patients using the panoramic unit system.

Results: The mean dose area product values for the adult panoramic X-ray examinations ranged from 32.97 to 97 (mGy.cm²), and for the pediatric panoramic X-ray examinations, they ranged from 29.85 to 73 (mGy.cm²). These results are numbers and the local diagnostic reference levels (DRLs) for dental panoramic radiography for pediatric and adults at 62.39 and 84 (mGy cm²), respectively. This is an essential standard for the safe and responsible use of panoramic X-ray exams, with direct implications for patient radiation protection and medical imaging optimization in Abu Dhabi, UAE. This research is particularly relevant for healthcare professionals, radiologists, dental practitioners, and policymakers.
