This study is to promote awareness to be exposed to radiation with identifying knowledge, attitudes and behavior for radiation safety management of the operating room nurse and dental hygienist. And the following results were obtained through questionnaire survey to deduct the education to prevent potential risks in advance and implication to be useful on education program. First, based on the level of knowledge for radiation safety management, 10.57 for dental hygienists, 9.55 for the nurse out of 15 points (p<0.001); based on the level of attitudes for radiation safety management, 4.64 for dental hygienists, 4.67 for the nurse out of 5 points (p<0.001); and based on the level of behavior for radiation safety management, 3.27 for dental hygienists, 2.93 for the nurse out of 5 points (p<0.001). Second, the result for checking the relation with knowledge, attitudes and behavior for radiation safety management, the knowledge of radiation safety management has correlation with attitudes and behavior for radiation safety management statistically (p<0.001).

This study identified knowledge, attitudes and behavior for radiation safety managemen of career dental hygienists and new dental hygienists. Results obtained from this study are as follows. 1. Regarding the knowledge level of radiation safety management, average score was $8.25{\pm}2.47$ for career dental hygienists and $7.42{\pm}2.77$ for new dental hygienists from 15 scale test.(p<.001). In addition, knowledge level of radiation safety management by general characteristics showed statistically significant difference according to health status(p<0.01). 2. Regarding the attitude level of radiation safety management, average score was $4.35{\pm}0.55$ for career dental hygienists and $4.19{\pm}0.60$ for new dental hygienists from 5 scale test.(p<0.01). 3. Regarding the behavior level of radiation safety management, average score was $3.14{\pm}0.98$ for career dental hygienists and $3.33{\pm}0.99$ for new dental hygienists from 5 scale test.(p<0.05). In addition, the behavior level by general characteristics showed statistically significant difference according to attendance rate of radiation safety management training (p<0.01) and defences of clinic (p<.001). 4. Based on the survey of relationship among knowledge, attitude and behavior of radiation safety management, we found that the higher the knowledge level of radiation safety management was, the higher the level of attitude was(p<.001).

The purpose of this study is to offer data base for establishment of dental training x-ray generator based safety usage through surveying real radiation safety management state of radiation worker's in plan of operations that have dental training x-ray generators and use it. For it, comprehensive references were surveyed referring reports of current state of regulation technique development and domestic radiation safety evaluation and nuclear related legislation regarding radiation safety management of dental training x-ray generators. On the basis of it, questionnaires were filled in about respondent's general characteristic radiation safety manager's status current state of radiation safety management and the level of knowledge & consciousness. For the study, the survey was conducted to 224 people of radiation safety managers and university graduates training assistants and full-time professors who can treat dental training x-ray generators in education center. through this survey 95 questionnaires were used as analysis materials except the insufficient and omitted responses. As a method of analysis, the frequency and percentage were figured out with the general characteristics and safety manager's status. Chi-square test for frequency and correlation per question analysis and Pearson correlation analysis for crosslevel correlation were done with current state of radiation safety management and knowledge & consciousness level. As a result, running dental training x-ray generators was dealt with by 20's to 40's who have high education level over post undergraduate degree and major in dental hygienic. In addition, female have higher consciousness level for radiation safety management than male. It shows significal linear relation statistically(${\chi}^2$ >5, 0.1${\chi}^2$ >5, 0.3${\chi}^2$ >5, 0.3

Recently, As people's interest in the health of teeth is increased in the medical field changed into aging society, the number of times for the radiological diagnosis is increased. It can be said that the radiation exposure dose of Korean population is increased. It is also growing concern about radiation exposure. Therefore, the basic data for the dental panoramic X-ray system, its investigation and measuring the radiation dose is needed. In this study, we used ALOKA PDM-117 dosimeter and estimated a two-dimensional dose distribution of the dental panoramic X-ray system (VATEC Pax-400). Dose evaluation about the distribution is confirmed from the point of radiation exposure of a patient. Dose distribution of the dental panoramic X-ray system irradiated chin and the facial region to high dose as well as the parts of teeth. It was founded that the eye lens which are sensitive to radiation are exposed to unnecessary radiation, considering the effect of scattered radiation. The results of this study will be used more accurate dose assessment in a variety of object size and location of measuring dose.

전남대학교 치과진료처에 내원한 환자의 구내방사선사진중 1단계 (Cl: 30개 병소)또는 2단계(C2: 213.8병소)의 인접면 치아우식을 가진 방사선사진 168장을 연구대상으로 하였다. 이들 방사선사진은 코닥사의 Ektaspeed(E group) 필름을 사용하여 평행촬영법으로 촬영하였다. 168장의 방사선사진에 대하여 1단계 및 2단계 치아우식증을 4명의 구강악안면방사선학을 전공한 치과의사들이 같이 판독하여 그 결과를 기록하였다. 또한 168장의 방사선사진을 필름-비디오 변환장치를 이용하여 디지털 영상으로 전환하였다. 이때 486 DX PC에 PCVision과 frame grabber를 이용하였다. 각각의 구내방사선사 진영상은 17"크기의 1280×768픽셀의 해상도를 갖는 모니터상에서 256단계 흑화도를 갖는 700×480픽셀로 제시되었다. 모니터상에서의 치아우식 판독 결과를 구내방사선사진 판독 결과와 비교하였다. 그 결과 sensitivity는 0.98이었다. 1단계 치아우식은 0.87, 2단계 치아우식 은 1.00의 sensitivity를 나타내었다.

A clinician's skills in a dental clinic are an important factor in removing the risk factors of patients. Although many universities have conducted educational programs, there has been a limitation on repeated practice because of the limited space and equipment. In dental radiography, there are various intraoral radiographic techniques. Since proficiency in radiography is an important factor in obtaining accurate radiographs, repeated practice and skill learning are important at the pre-clinical stage. However, the recent amendment of diagnostic radiation has caused difficulties in repeated practice on the human body. This study aims to develop a clinical simulator for intraoral radiography that enables repeated practice and self-directed learning without any restriction by utilizing the augmented reality technology to foster clinical skills for dental hygienist.

근관치료 후 성패는 근관치료 직후의 방사선 사진에서 보이는 근관충전의 양상으로 판단 될 수 없다. 근관치료의 성공을 위해서는 근관치료 직후의 방사선 소견과 주기적인 환자의 관찰을 통한 방사선 소견을 비교 평가하여 치근단 병소의 소실과 더불어 불편한 임상증상이 소실되었을 때 비로소 근관치료의 성공이라고 볼 수 있다.
