				        	Objective To investigate the status of quality control of dental X-ray equipment in Beijing Dongcheng District, to explore the problems involved in radiation protection. Methods 41 medical dental X-ray machines were detected in Beijing Dongcheng District in accordance with Specification for testing of quality control in dental X-ray equipment (WS 581—2017). Results The qualified rate was higher in imported machines (100%) than that in domestic machines (76.92%), the overall qualified rate was 92.68%. In performance detection, the qualified rates were 100% except for the deviation of loading time (92.68%) and tube voltage (95.12%). No leakage was detected in 41 dental institutes. Conclusion The overall status of dental X-ray machines was good in Beijing Dongcheng District. More attention was paid to shield protection than to quality control of dental X-ray machines. Therefore, health administration should take measures to strengthen advocation of WS 581—2017, and improve radiation protection through routine equipment performance test, supervision of X-ray protection and radiation health education.
