Abstract: Objective To understand the configuration,operation,workers and protection of dental radiotherapy equipment in Chaoyang District of Beijing,and provide reference for scientific management by regulatory authorities. Methods In 2023,relevant information on radiation diagnosis and treatment institutions equipped with oral X-ray equipment was collected through the Beijing Radiation Health Monitoring Database,and a unified survey form was developed to investigate dental clinics. Results There were 845 radiation workers in 336 radiation diagnosis and treatment institutions,with more women than men and an average age of 41 years old. There were a total of 612 oral X-ray equipment,with the highest proportion of first level medical institutions only equipped with intraoral dental machine（χ²=43.460,P<0.05）,and the highest proportion of third level medical institutions equipped with both extraoral and intraoral dental machines（χ²=22.200,P<0.05）. The allocation proportion of panoramic machines and CBCT were both the highest in clinics（χ²=52.640,65.900,both P<0.05）. The ratio of domestic equipment and imported equipment was 0.71 ∶ 1. The equipment rate of large collar lead rubber neck sleeve was >100% except the dental clinic. Among the 336 radiotherapy institutions,the highest proportion of radiologist operating equipment was 43.6% in primary hospitals and 51.6% in tertiary hospitals,the highest proportion of nurses operating equipment was 54.2% in secondary hospitals,and the highest proportion of doctors operating equipment was 60.1% in clinics. Conclusion The resources of oral radiation diagnosis and treatment equipment in Chaoyang District are at a leading level in Beijing,with 69% of radiation diagnosis and treatment institutions equipped with complete types of dental X-ray equipment,which can better meet the examination needs of different patients and dental diseases. The overall configuration of radiologists is insufficient,and the supervision of dental clinics should be strengthened from the perspective of the management of radiology staff and the provision of protective equipment.
