    Objectives : The objective of this study was to analyze cognition and status of oral health education of dental hygienists who manage the patients visiting dental clinics and to utilize the findings as continuous study data required for development of systematic oral health education program for management of peridontal disease of adults. Methods : Survey was carried out for 261 dental hygienists working in dental clinics who are performing oral health education of patients with peridontal disease living. Results : 1. In the socio-dynamic diagnosis, it was analyzed that, the younger the age is and the lower the career is, the more the work is centered around assisting medical treatment job and, the older the age is and the higher the career is, the work is centered around oral health education job. 2. In the behavioral diagnosis, it was analyzed that, as to source of knowledge acquisition, guide of dentists and senior dental hygienists was the highest and, as to education media, visual education and demonstration education were mainly used. 3. In educational diagnosis, as to the degree of knowledge about oral health education and the degree of practice, it showed that the degree of knowledge was lower than the degree of practice in peridontal disease process and oral prophylaxis as well as scaling part. 4. In both the cases of independent practice and group practice, it showed that the most frequent obstacle was insufficient educational materials and tools and it was analyzed that acquisition of new knowledge and technology is required as a matter to be improved. Conclusions : It seems to be required for the dental hygienists to develop detailed knowledge and professional technology in order to induce actions and motive of patients during oral health education of peridontal patients and to develop and produce data for efficient education of peridontal patients.

    control during dental practice and radiologic examination and to evaluate the dental hygienist’s awareness of the importance of infection control in dental office. Methods : A survey on 218 dental hygienists was carried out. The respondents to complete a questionnaire were the dental hygienists who were in dental office on Gwang-ju area or attended complementary training conducted by the Seoul Branch of Korean Dental Hygienists Association in April 2010. The data were collected and analyzed with x²test, t-test, ANOVA using SPSS program. Results : The ratios of educational experience for infection control in dental practice and radiologic examination room accounted for 87.6% and 30.3% respectively. Behavior degree of mask-wearing in the dental practice and radiologic examination room were 4.60±0.70 and 3.77±1.09 respectively. Behavior degree of glove-wearing in the dental practice and radiologic examination room were 4.40±0.91 and 3.68±1.17 respectively. In case of the relation between educational experience and behavior degree in mask-wearing or glove-wearing, there was no significant difference in the performance of mask or glove wearing during dental practice, and mask-wearing during radiologic examination. However, there was a significant difference (p<0.05) in the performance of glovewearing during radiologic examination, which revealed that behavior degree between the respondents having educational experience and the others no having it were 3.92±1.19 and 3.58±1.14 respectively. The surface disinfection control for radiation and protective equipments used in radiologic examination room was done by occasional needs without premeditated schedules. Conclusions : The result of this study shows lower behavior degree during radiologic examination compared with one during dental practice. We suggest that there are needs?to raise the awareness of infection control and to improve infection control behavior, and through this study, the importance of education was verified.

    윤성욱 | 김정숙 | 2011, 11(2) | pp.179~188 | number of Cited : 42
    Abstract PDF
    Objectives : The study set out to analyze correlations between emotional labor and job stress among dental hygienist, who have direct and lasting relationships with patients in dental clinic, and provide basic data to resolve stressors and manage stress. Methods : A survey was taken among dental hygienists working at dental clinics, and 200 questionnaires were used in analysis. The gathered data were put to Cronbach’s alpha with the SPSS WIN12.0 program to test the reliability of the inventories to measure their emotional labor and job stress. In addition, correlation analysis was conducted to examine relations between the items of emotional labor and those of job stress along with regression analysis to examine relations between emotional labor and job stress. Finally, t-test and One-way ANOVA were conducted to test mean differences in the job stress items according to the degrees of emotional labor with the statistical significance level set at 0.05. Results : 1. The measurement tool used in the study recorded 0.7 for all the areas of Cronbach’s alpha for internal reliability and thus achieved high reliability. 2. The overall mean of emotional labor was 2.74, which indicates that the dental hygienists had‘ average’or higher stress for emotional labor. 3. Emotional labor had statistically significant relations with educational background, place of work, motivation to choose to be a dental hygienist,and religion of their general characteristics. 4. There was statistical significance in relations between general characteristics and job stress according to educational background, position at work, and experience with change of occupation. 5. The correlations between emotional labor and the stress areas were analyzed. As a result, emotional labor was in positive(+) correlations with job demand, lack of job autonomy, relational conflict, job instability,organizational system, and corporate culture. In addition, regression analysis was conducted to test causal relations between emotional labor and job stress. The results indicate that there were positive(+) influences between emotional labor and job stress. Conclusions : The results show that emotional labor can serve as a mediating variable for job stress in dental clinic. Thus both dental clinics and dental hygienists need to have ways to deal with job stress derived from emotional labor in which they are forced to process their emotions according to the dental clinics’demands, properly. The study will hopefully trigger ongoing follow-up researches on the deployment of dental hygienists according to their job characteristics and the situational variables to alleviate the negative results of emotional labor.

    이선미 | 김수화 | 2011, 11(2) | pp.189~196 | number of Cited : 12
    Abstract PDF
    Objectives : This study aimed to get the data necessary for dental hygiene students to perceive the need for establishing a professional identity as dental hygienists and developing a program which reinforce pride as a preliminary professional. Methods : The subjects were 695 dental hygiene students in Seoul, Gyeonggi and Chungcheong areas. The collected data were analyzed using the SPSS program. Results : 1. The professional identity of dental hygiene students was 3.02 points, and the satisfaction with institutes for practice was 2.96 points. 2. The higher the satisfaction with the major was, the higher the identity was. Also, the identity was high when the frequency of clinical practice was 1 (3.11 points) and when they selected their major which corresponds with his aptitude (3.20 points). 3. The satisfaction with clinical practice was high when they didn’t have any experience in dental clinic before clinical practice and when the satisfaction with the major was high. 4. Regarding the correlation between the professional identity and the satisfaction with clinical practice, the higher the satisfaction with clinical practice, the higher the professional identity. 5. The effective variables regarding the professional identity were satisfaction with a major, satisfaction with clinical practice,and frequency of clinical practice. Conclusions : The professional identity of students may be established through school education involving clinical practice. The identity of students may affect the occupational satisfaction, the identity and the work efficiency of dental hygienists in the future. Thus, it is deemed necessary to have a continued collaborative relationship between a school and an institute for clinical practice so that students may establish their correct views and identity.

Methods : This research was conducted from July 17th, 2010 to August 16th, 2010 targeting 600 residents in Goryeong-gun, Gyeongsangbuk-do, aging over 40. The data has been analyzed using Mann-Whitney U test,Kruskal-Wallis test and hierarchical multiple regression through SPSS Win Program 18.0 version. Results : 1. OHIP-14 based on general characteristics showed lower oral health-related quality of life on the following cases: women(p=0.004), older(p<0.001), lower scholastic ability(p<0.01), lower average of average spending money(p<0.001), higher number of chronic disease (p<0.001), less drinking(p=0.012) and lower cognition of subjective oral health and health status(p<0.001). 2. OHIP-14 based on oral health behavior showed lower oral health-related quality of life on the following cases: no periodic oral check-up(p<0.001), less experience of oral health education(p<0.001), lower frequency of tooth-brushing(p=0.042) and horizontal tooth-brushing method(p <0.001). OHIP-14 based on oral health status and subjective oral symptom showed lower oral health-related quality of life on following cases: number of existing tooth less than 20(p<0.001), the number of missing teeth more than 9(p<0.001), DMFT (Decay, Missing, Filling Teeth) index more than 18(p<0.001), wears denture (p <0.001), edentulous(p<0.001), have xerostomia (p<0.001) and have chewing discomfort(p<0.001). 3. EQ-5D based on general characteristics showed lower health-related quality of life on the following cases: women(p <0.001), older (p<0.001), lower scholastic ability (p<0.001), lower average of average spending money(p<0.001),higher number of chronic disease(p<0.001), non smoking and drinking(p<0.001, p=0.008) and lower cognition of subjective oral health and health status(p<0.001). 4. EQ-5D based on oral health behavior showed lower healthrelated quality of life on the following cases: no periodic oral check-up(p<0.001), less experience of oral health education(p<0.001), and horizontal tooth-brushing method(p<0.001). EQ-5D based on oral health status and subjective oral symptom showed lower health-related quality of life on following cases: number of existing tooth less than 20(p<0.001), the number of missing teeth more than 9(p=0.044), DMFT (Decay, Missing, Filling Teeth)index more than 18(p<0.001), wears denture(p<0.001), edentulous(p=0.002), have xerostomia(p<0.001) and have chewing discomfort(p<0.001). 5. Factors affecting OHIP-14 were gender, age, cognition of oral health, cognition of health, number of existing teeth, condition of the set of teeth, xerostomia and chewing discomfort, and the of reliability (how well it explains) the final model was 48.7%. EQ-5D showed relevance on gender, age, presence of chronic disease, cognition of health, xerostomia, chewing discomfort and oral health-related quality of life, and the reliability of the final model was 42.9%. Conclusions : In order to improve the quality of life of ruralists, oral health needs to be improved or remained by increasing the rate of possession of the existing teeth and preventing the loss of teeth. In order to do so,improvement of accessibility of dental clinic, change of direction from treatment-centered to prevention-centered health care system, development of oral health education program and various oral health care policies which would vitalize continuous oral health care system are considered to be necessary.

    Sung-Hee Kim | 김민자 | 남용옥 | 2011, 11(2) | pp.277~291 | number of Cited : 5
    Abstract PDF
    Objectives : This research was organized to discover the awareness of problems and improvement ways of application system for recuperation allowance. Methods : Therefore 1,135 of questionnaires were organized to send to the demanders of dental clinic recuperation allowance in Daejun Metropolitan City and Southern & Northern Chungchung area, registered in Health Insurance Review & Assessment Service by May 2010. 207question naires of being very well answered were chosen to analyze. And there sults were derived like below. Results : 1. Most of the responders are engaged with Dental clinic centers. The proportions of receptionists, who have been worked for more than 5 years, are the most. And 10~50% of application were the most. 2. The awareness about the standard of fee for consultation and diagnosis were average. The negative awareness was relatively often generated from the health center which processes the invoice as pay per day system rather than dentists of university hospital where charge per treatment. Regarding positions, dentists were claimed to be inappropriate and there was a meaningful difference (p<0.05). For the reason of awareness, most of the responds were represented to be negative as they claimed that the system was designed for convenience of dentists rather than for the patients by examining the objective judgments. 3. The examples of judgments should be opened to the public, according to the responders. Regarding the judgment control of insurance application, most of the answers were assorted to be into two groups; ‘Do not have enough information about judgment standard’and ‘error of disease, code and program’. Therefore the responders answered that they have ever been controlled by convenience of the medical centers so it generated the meaningful difference (p<0.05)4. About solutions after judgment control, ‘knowing the reason of judgment control from the acquaintances of Health Insurance Review & Assessment Service then reflect’was the highest. The dental clinics of University Hospital and private dentists were shown to be them ostactive participant of this system. Concerning of the posi-tion, agents of application are shown to be the active participants for objection application process. There was also a meaningful difference(p<0.05) 5. The reason for not claiming objection was indicated that the awkwardness or inconvenience of communication with Health Insurance Review & Assessment Service was 20.9%. Therefore it is analyzed to demand the diversity of communication methods between Health Insurance Review &Assessment Service and clinic centers and shift to the clinic center. But it was hard to find the meaningful difference so far. 6. About the awareness of improvement for correcting errors, generated from insurance application process, priorities were sorted out to be improvement of application program setting, accurate charting of diseases and treatments. The awareness of Dental clinics of University hospital and private dentist were the highest whereas the health center was relatively low. It generated the meaningful difference (p<0.05). About the opinion of the professional employees for insurance application and its judgment, dental clinics of university hospital and private dentists were the highest, dentists were the lowest regarding the positions. 7. Positive responds were the most egarding the awareness about reading the treatment details and charges. However, 50% of dentists opposed to this, therefore it was shown a noticeable difference from other groups. It also generated a meaningful difference. (p<0.05)Conclusions : When national Health Insurance Review Agency and dentistry medical treatment organization cooperated each other, successful factors of the adjustment variables which were derived if a synthesis tried the above-mentioned result of research were thought to realizable things.

    Abstract PDF
    Objectives : The aim of the trial was to study the effect of plaque control(tooth brushing instruction) for oral health improvement on periodontitis patients. Methods : 30 patients(35~65 years) with advanced periodontal disease were subjected to a baseline examination including assessment of oral hygiene status(O’leary index), gingival condition(bleeding). the assessment were repeated after 2, 4, 6 weeks. cognitive, behavioral and clinical outcomes were assessed in the primary care setting by questionnaire and clinical oral examination. Results : The oral hygiene status expressed as the individual mean percentage of tooth surfaces with plaque 59.3% at baseline and 21.2% after 6 weeks(p<0.001). The gingival bleeding status expressed as the individual mean point of interdental papilla 3.8 at baseline and 1.9 after 6 weeks(p<0.001). Also, the patients self-assessment about correct tooth brushing behavior was 3.9(5-point likert scales), satisfaction of plan practices 4.1(5-point likert scales), efficacy of tooth brushing instruction 8.7(10-point likert scales). Patients wanted to continuous participation. Conclusions : A verification of effect after individualized oral health instruction and repeated dental plaque control represented to significance on plaque control score, oral care practice and oral health recognition. The important oral care step against periodontal disease is to establish good oral health habits. Also, oral health behavior recognition is more important for the practice of oral health. Therefore professional plaque control and tooth brushing instruction absolutely need in improving oral health.
