This study aims to provide a basis for improvement of the working environment and human resource management in the field of dental hygienists by reducing the negative factors of emotional labor, which are required by dental hygienists, and identifying positive factors that increase job satisfaction. The subjects were 507 dental hygienists in Seoul, Daejeon, Chungnam and Jeju province from October 13 to November 17, 2013. Data were self-reported questionnaires. 1. Deep-acting of emotional labor of the surveyed subjects showed 3.356 points which is higher than 3.301 points shown in surface-acting. In case of job satisfaction, the average point was 3.350 and the rate of social support perceived by the surveyed subjects was 3.428 points. In the case of goal orientation, the learning goal orientation point was 3.832, which is higher than that of performance goal orientation, which was 3.788 points. 2. The deep-acting had statistically significant positive correlation with social support, learning goal orientation and performance goal orientation. In addition, surface-acting showed a statistically significant positive correlation with learning goal orientation and performance goal orientation, and a statistically significant negative correlation with social support. The job satisfaction had a statistically significant positive correlation with deep-acting, social support, learning goal orientation, and performance goal orientation. 3. A gradual stepwise multiple regression was conducted to identify the factors that affect job satisfaction, and it was found that job satisfaction point was higher among the married, and has increased according to the increases of deep-acting, social support, learning goal orientation, and performance goal orientation. To improve job satisfaction, dental healthcare institutions should be required to attempt organizational changes and develop service education, self-development programs in order to raise goal orientation as part of human resource management.

Replace the degree of dental apron Hospital (t=-8.40, p<.001) with the overall average of 2.69 points out of three surgical operations (F=5.50, p<.01), B hepatitis vaccination performed (t=7.71, p<.001), showed a significant difference in infection-related education experience of (t=7.75, p<.001). 4. All instruments disinfection and sterilization of dental hygienists are using an average of 2.66 points showed that all the instruments disinfection and sterilization is always used. 30 years of age (F=4.53, p<.05), the dental clinic (t=-6.15, p<.001), surgical operations (F=10.73, p<.001), B hepatitis vaccination performed (t=8.03 , p<.001), showed a significant difference in infection-related education experience of (t=11.04, p<.001). 5. Dental Clinic dental hygienist was a high degree of infection control practice, showed significant differences depending on the employer (t=-7.75, p<.001). Surgical operations (F=15.93, p<.001), B hepatitis vaccination (t=11.05, p<.001), showed a significant difference in infection-related education experience of (t=12.86, p<.001). Infection control practice of dental hygiene as described above usually was, dental, hospital, surgical services, B hepatitis vaccination carried out, the higher the degree of infection control practice dental hygiene in infection-related education experience. Action is also required infection control practices and the importance for low-masks, protective equipment, medical gowns replaced.

The purpose of this study was to examine the state of infection control among employees in charge of the dental supply room in an effort to determine how to ensure the efficient implementation of infection control standard. The subjects in this study were every employee in charge of the dental supply room in a university hospital located in Gyeonggi Province, who numbered 20. A self-administered survey was conducted from June 1 to 30, 2015. The findings of the study were as follows: 1. As for the responses of the subjects on the danger of infectious diseases, the largest group that numbered 11(55.0%) considered hepatitis B to be most dangerous, followed by AIDS(four respondents, 20.0%) and influenza(three, 15.0%). Tuberculosis and viral dermatitis were respectively pointed out by one employee(5.0%). As for medical examination by interview about infectious diseases, 18 respondents(90.0%) answered it should be done every time, and two(10.0%) replied, "Not necessarily." Every respondent answered the responsibility of infection control lay with dentists and the dental staff. 2; Regarding the awareness of the subjects on infection control, they gave the highest average score of 4.75 to the item "Every glove for medical use should be discarded after its use during treatment." And they gave the lowest mean score of 3.6 to the item "A new mask should be used whenever there's a new patient." 3. As to their practice of infection control, they gave the highest average score of 4.63 to the item "Every glove for medical use should be discarded after its use during treatment." And they gave the lowest mean score of 3.63 to the item "I change my uniform after treating a patient who has an infectious disease." 4. They gave a mean of 3.47 when their expectations were asked before they received infection control education, and they gave 4,13 when their satisfaction level was asked after that education. They gave 4.2 respectively when their understanding and substantiality of what they learned and their understanding of the education were asked. 5. Before they received the infection control education, they gave a mean of 4.12 to the importance of infection control duties, but they gave a higher score of 4.24 after that education. Their score in efforts to carry out the infection control process was 3.94 before that education and rose to 4.24 after that. Their scores in errors in job performance in the dental supply room was 3.35 before the education, and then dropped to 0.76 after that.

The purpose of this study was to provide useful information on the harmfulness of smoking in adolescence and how to motivate adolescents to stay away from smoking. The 2010 and 2012 National Health & Nutrition Examination Survey data were used to analyze the impact of the time for starting smoking on the occurrence of periodontal diseases in adults aged 20 and up in Korea. 1. As for the start time for smoking by sociodemographic characteristics, there were significant differences in that regard according to residential area, gender, age, academic credential and income. Concerning the formation of periodontal pocket by sociodemographic characteristics, there were significant differences according to residential area, gender, age and academic credential. 2. In relation to the time for starting smoking by health status, there were significant differences according to hypertension and alcohol disorder. But diabetes showed no statistically significant differences to that. Regarding the formation of periodontal pocket by health status, statistically significant differences were found according to the severity of diabetes, hypertension and alcohol disorder. 3. As to the formation of periodontal pocket by smoking, only the frequency of smoking showed differences to that, and no differences were found according to the duration of smoking and the start time for smoking. 4. The respondents who were rural residents, who were male, who were older and who had more dental caries have the higher risk of periodontal pocket formation. The start time for smoking didn't affect the formation of periodontal pocket, but this finding didn't seem to suggest there would be no possibility that it might exercise a secondhand influence on the formation of periodontal pocket by impacting on oral hygiene and smoking behavior.

Our study focused on etiologic factors for tooth extraction and extraction age for patients in medical clinics of suwon area. 3,357 teeth were selected for this study extracted between January, 1, 2010 to December, 31, 2012. The etiologic factors for teeth extraction retrospectively classified to KCD, and the results were as follows. 1. Periodontal diseases 37.5%, dental caries 29.0%, pericoronitis and impacted teeth 21.5%, radicular cyst 5.5%, fracture of teeth 3.4%, and the orthers 3.1%. 2. According to the age, pericononitis and impacted teeth was most prevalent before fourth decade and the most prevalent after that was periodontal diseases. Extraction caused by dental caries was commonly the second most prevalent in all age groups(p<.05). 3. According to sex, extraction by periodontal diseases was prevalent in male(39.6%), and that by dental caries was prevalent in female(34.7%)(p<.05). 4. In comparison of upper and lower jaw, both jaws were prevailed by periodontal diseases. and the extraction by radicular cyst was prevalent in lower jaw(7.9%) in contracst to upper jaw(3.4%)(p<.05). 5. According to tooth type, all extracted teeth was caused by periodontal diseases except upper and lower 3rd molar. Among them, the most frequent tooth type was lower second molar(8.2%) and the least frequent tooth type was lower canine(2.2%)(p<.05). 6. Male was earlier(46.1years) than female(48.8years) in consideration of extraction age. The earlest extracted tooth was lower first molar(52.1years) and the latest extracted one was lower canine(68.1years) except wisdom teeth(p<.05).
