According to current medical service act, a manager for radiation safety can remain in the position if the person receive training or continuing education only once a year. This research found out that the radiation safety managers perform their functions with inadequate specialized training. I think that any specialist needs acquisition of new knowledge and having an awareness about their own business through regular refresher training although the person is eligible for the work. However, current radiation safety system have a large number of problems. If the person who does not receive enough training to have expertise in radiation safety and has not accurate knowledge about the harmfulness of radiation exposure is continually appointed as the radiation safety manager, we can not expect high quality health and medical treatment. Therefore, it is necessary that the current provision, that is, the selected radiation safety manager need to receive training only once the year revise that the manager should receive refresher training every year. Now, the radiation safety manager of dental hospital or dental clinic is a dentist, a radiological technician, or a person who works in diagnostic radiology more than three years as dental hygienist(except the dental clinic or dental hospital equipped ‘Panorama’ or ‘Cephalo’). I think if a dentist is appointed as the radiation safety manager, the person need to received refresh training every year. If not, it is hard to expect that the dentist is continually aware of the harmfulness of radiation. If a dental hygienist who actually conducts radiography is appointed as a radiation safety manager, it is necessary that the person should have further education about radiation field and spend substantial amount of time for radiation education during the refresh training of dental hygienist. Because the dental hygienists do not have professional knowledge and skills about radiation field if they only receive the current training. The other alternative is dental clinics employ a radiological technician and appoint the person as radiation safety manager. If the dental clinics do this, they can provide patients with high quality medical care because the radiological technicians have sufficient knowledge and skills about radiation safety.

이은경,장계원 한국구강보건과학회 2022 한국구강보건과학회지 Vol.10 No.3

Objectives: This study was conducted to investigate how anxiety in dental patients regarding radiation exposure can be reduced. Methods: The study was conducted in dental facilities during the six months from August 2019 to January 2020 to investigate the anxiety of patients concerning radiation exposure. It then analyzed the factors affecting their levels of anxiety regarding exposure. Results: The results showed statistically significant differences between anxiety relating to dental radiation exposure and knowledge of radiation (-0.252, p < 0.01) and perceptions of radiation (-0.582, p < 0.01). An examination of the factors affecting the anxiety of dental patients regarding exposure to radiation showed that a high recognition of the need for dental radiography (p < 0.05) and more negative perceptions of radiation (p < 0.001) resulted in greater anxiety regarding radiation exposure (p < 0.001). Conclusions: In order to reduce anxiety about radiation exposure, educational materials should be produced and patient education conducted so patients can have correct knowledge and perceptions of dental radiation. In addition, relevant regulations or legal guidelines should be prepared so that radiation safety education for patients can be practiced systematically.

치과에서의 방사선안전관리

이삼선 대한구강악안면방사선학회 2007 Imaging Science in Dentistry Vol.37 No.3

Although the diagnostic information provided by radiographs may be of definite benefit to the patients, the radio-graphic examination does carry the potential for harm from exposure to ionizing radiation. Therefore we should try to expose radiation as low as reasonably achievable and to give diagnostic information to patients as much as possible. All of dentists should have competence in radiation protection, I wish to deal with what we should do for the optimization of radiation protection in dental clinic.

김은경(Eun-Kyung Kim) 대한치과의사협회 2014 대한치과의사협회지 Vol.52 No.3

Recently the patient exposure by medical and dental x-ray examination has grown rapidly and diagnostic radiology represents the largest source of man-made radiation. For the patient protection, the principle of justification and optimization should be followed. All the radiographic examinations have to show a potential benefit to the patient weighing against the potential risk. After they are justified, the radiographic exposure should be kept as low as reasonably achievable, taking into account economic and social factors. For the safe use of radiation in dentistry, the radiation safety management in accordance with the legislation is important. The present status and the future of radiation safety management in dental radiology in Korea and other country will be discussed.

CBCT의 선택과 처방

안창현(Chang-Hyeon An) 대한치과의사협회 2014 대한치과의사협회지 Vol.52 No.3

The emergence of Cone Beam Computed Tomography(CBCT) in the late 1990s represented an innovative advancement in the field of dental and maxillofacial radiology because it greatly reduced the radiation exposure to patients and offered 3D images easily. The 3D information generated by this technique brings the potential of improved diagnosis and treatment planning for a wide range of clinical applications in dentistry. The use of CBCT includes diagnosis and surgical assessment of the orofacial hard tissue lesions, dental implant treatment planning and postoperative evaluation, TMJ assessment, diagnosis of craniofacial fracture, orthodontics, endodontics, and so on. All CBCT examinations should be justified on an individualized needs. The clinical benefits to the patient for each CBCT scan must outweigh the potential risks associated with exposure to ionizing radiation. CBCT scans should be taken with initially obtained medical and dental histories of patients and a close clinical examination. CBCT should be considered as an imaging alternative of other conventional radiography in cases where the anatomical structures of interest may not be seen. The smallest possible field of view(FOV) and the lowest setting of tube current and scan time should be chosen, and the entire images scanned should be interpreted by a qualified expert.
