Guidelines for radiation protection in dental radiographic examinations: a questionnaire-based summary

Abstract

ABSTRACT We aimed to develop a dental radiation protection guideline for patients and dental personnel through a questionnaire on safety management in dentists, radiological technologists and dental hygienists at dental institutions. The survey of dental institutions was conducted and statistically assessed. In the image receptor system of intraoral radiograph, film-based type (11.3%), DR type (34.9%), and panoramic radiograph of film-based type (8.3%) and DR type (22.1%) were included. Genital protector (92.9%), thyroid gland protector (65.4%), lead gloves and lead glasses (95.4%), and shielding devices (0.7%) were not used. Based on the results of the study, exposure protection apparatus, patient’s image acquisition by licensed radiologists, and reduction of exposure levels by dental personnel are needed, in order to achieve safety in dental examinations. Radiation protection and safety management at dental institutions was insufficient, and dental personnel should utilize current radiation safety management guideline and continuing education to enable dose management.
