The purpose of this study is to investigate the calibration of an optically stimulated luminescent nanoDot dosimeter(OSLnD) to 6 MV photon beam. Dose ranges of the calibration of linear and non-linear from the analysis of dose response of the OSLnD were decided. To evaluate the accuracy of calibration equation and the calibration, the sets of the calibration and quality control dosimeter were used to make. The calibrations were performed by the linear and the non-linear in the dose range of 0~300 cGy and 20~1300 cGy, respectively. The errors of the calibration were acquired less than 0.1% respectively from the measurement of the quality control dosimeters for the calibration of linear and the non-linear. This study provides the calibration equation of the OSLnD to the 6 MV photon beam.

This study is aimed at providing the variables associated with adolescent compliance In orthodontic treatment, and identifies the salient predictors of cooperative behaviors over the course of treatment. Orthodontic attitude scale, orthodontic locus of control scale and demographics data were obtained for 60 adolescent orthodontic patients who had been in treatment a minimum of 10 months. This data was then analyzed in relation to their sex, school age and treatment compliance. The following results were obtained. 1. The scoring of external-powerful others-parents, subscale of the Orthodontic Locus of Control scale, found a statistically significant difference between sex differences (p<0.05). The score of boys was higher than that of girls. 2. The external-powerful others-parents score from the Orthodontic Locus of Control scale showed a significantly positive correlation (p<0.05) with the level of compliance. 3. The salient factors associated with compliance were the adolescent patients' own cognition and decisions. 4. There was a statistically significant correlation between the length of treatment and patient compliance (p<0.05). Thus, there was a substantial decrease in the cooperation of orthodontic patients over time. 5. Other independent variables including age, sex, family environment, religion, academic standing, parents' occupation and education, and brushing frequency were investigated and did not yield any significant relationships. Patient compliance is a critical factor in the efficacy of orthodontic treatment. Individuals vary greatly in their perceptions and attitudes of orthodontic treatment, sociodemographic environments and personality characteristics. In assessing the level of compliance attainable by each individual patient it is advisable To pay sufficient attention not only to the technical matters but also to the psychologic aspects of the treatment progress.

As people are more concerned about their health and medical care, there have been an increasing number of medical disputes due to increased medical demand. In order to prevent and provide solution to currently surging medical accidents and disputes related to orthodontic treatment, in July 1998, the Korean Association Of Orthdontists surveyed 2,200 members of Korean Association of orthodontists on 30 items to recognize the pattern of medical accidents and prevent them. The survey was about accident-related items including personal profiles of members and patients who have undergone medical accidents or disputes, the cause and solution to the accidents, cautions related to members orthodontic treatment, and medical recording and archival. Based on the survey result, we analyzed characteristics of medical accidents and disputes in orthodontic area. It is more important to predict and prevent possible medical accidents or disputes based on current situation than to solve them after disputes occur. For this, we should not be negligent in raising treatment proficiency level based on patient-doctor trust and in obtaining new medical information. We should also provide medical environment where Patients themselves can decide whether to get treatment after they are offered detailed explanation on diagnosis, treatment procedure, complication, and possible hazard. We should take caution when treating patients and pay attention to charting and maintenance, which is the most fundamental, as well. Also at the Korean Association of orthodontists level, it is desired to provide education program on prevention and solution to medical accidents and disputes, and actions and organizations that can help when accidents and disputes occur.

The present study surveyed 300 adults who completed orthodontic treatment to determine their oral health-related quality of life and changes in oral health behavior in orthodontic patients. The collected data is analyzed using the spss 22.0 program. Before orthodontic treatment, social factors (4.68) had the lowest associated quality of life score, and after orthodontic treatment, socially related quality of life showed the highest increase at 3.72 points. Changes in oral health behavior showed that many phosphorus scaling increased by 1.28 points after correction compared to before correction. As oral health quality of life and oral health behavior have changed through orthodontic treatment, dental professionals need to take appropriate management of each patient's individual quality through health education. Appropriate management needs to be developed.

The purpose of this study was to promote effective health management of orthodontics patients by determining the effect that the factors related to orthodontics would have on the Oral Health Impact Profile (OHIP), and the subjects of this study was the local residents of Gangwon-do Province. The mean score of OHIP for the subjects was 2.97, while the mean score of physical factor was 3.01. The mean score of psychological factor was found to be 2.93. Thus, the orthodontics was found to have more influence on psychological factor. The item that had the greatest influence among the 10 items of Oral Health Impact Profile was found to be the question, "Have you ever felt shy due to your dental shape?" which had the mean score of 2.66. The characteristics that had significant effect on OHIP among general characteristics were found to be the age, religion, occupation, income, smoking or non-smoking status(p<0.05). In terms of the age, the age of 20 or less had the greatest effect with the mean score of 2.53. In relation to the occupation, the production/sales occupation had an influence with the mean score of 2.56 (p<0.05). Those with income exceeding KRW 4 million were found to have the mean score of 2.83 and 2.78. It turned out that the smokers had greater effect compared to the non-smokers in relation to the smoking/non-smoking status as the income was higher (p<0.05). The characteristics of orthodontics were manifested as the health perception in relation to Oral Health Impact Profile (OHIP) (p<0.05). Regarding the reason why they underwent the orthodontics, the 'uncomfortable feeling in chewing' was found to have the mean score of 2.69 and 2.67 (p<0.05). Regarding the orthodontics period, 1 to 2 years were found to have the mean score of 2.80 and 2.74, thus having an influence (p<0.05). In relation to the regret/non-regret over orthodontics, those who indicated that they regretted were found to have the mean score of 2.65 and 2.60 (p<0.05). Analysis of the relationship between Characteristics of orthodontic treatment and OHIP, orthodontic treatment reasons, oral health awareness, whether orthodontic treatment regret showed a statistically significant correlation. it is considered necessary to make constant efforts to help orthodontics patients, both physically and psychologically, in the course of treatment and improve their quality of lives.
