Objectives : This study aimed at examining the aspects of utilization of the dental services in some regions and analyzing the related factors with a view to helping the old solve the dental problems and overcome the difficulties. Methods : This investigation was intended for 422 old people living in Jeon-ju city and Jang-su county from July 18, 2006 to August 25 by direct interviewing posing questions. The survey data sets were analyzed by chi-square, correlation, multiple regression and logistic regression. Results : 1. The average number of the existing teeth per an old person was 13.6 and the 28.8% of the old who didn't use denture called for dentures. 2. The annual coefficient of utilization in dental services for an old person was 52.3% and the annual average visits to dental clinics were 3.12 days while 38.6% of the old experienced illegal dental treatments. 3. The affecting factors on the dental utilization for treatment were as follows: family income, dental clinics available, the number of existing teeth, the days of dental trouble, the recognition of the prevention of the dental disease, the knowledge for the dental treatment and the oral health judged by himself. 4. The major variables influencing the utilization of dental services were spouse presence, form of family, income, having a regular dental care, denture presence and the experience of inconvenience in living. Conclusions : To conclude, the following suggestions could be made. First, It was necessary that enforcement practice of free dental prosthesis service and application to the national health insurance in old people's prosthetic therapy for government support because the economic factor was barrier to utilization of the dental services. Second, Dental clinic was required to the health center because availability of common dental services was big impact in utilization of the dental services.

Head-lice infestation, pediculosis capitis, remains a public-health burden in many countries. The widely used first-line pediculicides and alternative treatments are often too costly for use in poor socio-economic settings. Ivermectin has been considered an alternate treatment for field practice. This study was composed of 2 parts, a cross-sectional survey and an intervention study. The main objectives were to determine the prevalence and potential factors associated with head-lice infestation, and to evaluate the effectiveness and safety of oral ivermectin administration. A community-based cross-sectional survey was conducted among 890 villagers in rural areas along Thai-Myanmar border. Females with infestations were eligible for the intervention study, and 181 participated in the intervention study. A post-treatment survey was conducted to assess acceptance of ivermectin as a treatment choice. Data analysis used descriptive statistics and a generalized-estimation-equation model adjusted for cluster effect. The study revealed the prevalence of head-lice infestation was 50% among females and only 3% among males. Age stratification showed a high prevalence among females aged <20 years, and among 50% of female school-children. The prevalence was persistent among those with a history of infestation. The major risk factors were residing in a setting with other infected cases, and sharing a hair comb. The study also confirmed that ivermectin was safe and effective for field-based practice. It was considered a preferable treatment option. In conclusion, behavior-change communication should be implemented to reduce the observed high prevalence of head-lice infestation. Ivermectin may be an alternative choice for head-lice treatment, especially in remote areas.

The purpose of this Study was to examine the effect of perfectionism on stress and anxiety during scaling practice in an effort to find efficient way of helping students with getting good skills. The subjects in this study were students who practiced a scaling at the oral hygiene practice lab in the Department of dental hygiene in S college from May 1 to May 31, 2008. They were divided into four groups based on their subscales of perfectionism : mixed perfectionist group, achievement striving perfectionist group, failure avoidance perfectionist group and non-perfectionist group. The measurements used were Two-Dimensional Perfectionism Scale, Stress level, Trait anxiety, State anxiety. There were no significant differences in the stress level before practice between 4 groups. There were significant differences in trait anxiety, state anxiety, total anxiety before scaling practice between 4 groups. However, these results were due to differences between mixed perfectionist group and non-perfectionist group. After practice, total anxiety was decreased from 93.71 to 89.66 and state anxiety was decreased from 45.49 to 43.38. These results were statistically significant. In order to investigate the influence of achievement striving factor and failure avoidance factor on the change of state anxiety during the scaling practice Standard Multiple Regression were employed for the statistical analysis. Failure avoidance factor was related with the increase of state anxiety during the scaling practice. So leachers have to give all effort to reduce the anxiety of students during scaling practice and provide students with motivation of achievement.

Objectives : This study was conducted to investigate the actual state of dental hygienist's behavior for infection 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 $x^2$ test, 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 $4.60{\pm}0.70$ and $3.77{\pm}1.09$ respectively. Behavior degree of glove-wearing in the dental practice and radiologic examination room were $4.40{\pm}0.91$ and $3.68{\pm}1.17$ 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 glove-wearing during radiologic examination, which revealed that behavior degree between the respondents having educational experience and the others no having it were $3.92{\pm}1.19$ and $3.58{\pm}1.14$ 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.

Background: To analyze the effect of self-regulation on the fear of dental treatment in order to use it as basic data for efficient oral health care among male adolescents. Methods: A survey was administered to 241 first graders of specialized high schools in Daegu using a self-entry method. Twenty questions about fear of dental treatment and fifteen questions about self-regulation were included. The higher the score, the higher the fear of dental treatment and the self-regulation ability, showing a high reliability of 0.972 and 0.750, respectively. Results: The mean score of the participants' self-regulation ability was 3.25±0.51 and that of the degree of fear for dental treatment was relatively low at 1.72±0.85. It was confirmed that the higher the academic performance (F=7.635, p<0.01), the better was the self-regulation based on self-diagnosis (F=3.142, p<0.05), and was associated with higher health awareness (F=5.894, p<0.01). The degree of fear for dental treatment was significantly higher in the self-diagnosis-induced poor health group (F=4.933, p<0.01) and associated with a lower awareness of health (F=3.093, p<0.05). The participants' self-regulation ability was significantly negatively correlated with the degree of fear regarding dental treatment (r=-0.269, p<0.01). Regression analysis was performed using the degree of fear as a dependent variable and including sub-area variables of self-diagnosis-based health status, perception of health, and self-regulation ability as independent variables (β=-0.163, p<0.05). Among the self-regulation abilities, controlled composition (β=-0.232, p<0.01) had a significant effect; the higher the composition, the lower the degree of fear. The total explanatory power of this variable was 8.5%. Conclusion: An appropriate customized education program that can encourage individuals to practice self-care and maintain oral hygiene along with a clear understanding of underlying individual oral health conditions during adolescence is essential for promoting oral health.

Objectives : The purpose of this study was to examine the oral health knowledge and actual oral health care of the selected subjects, their decision making about prosthetic treatment, the state and characteristics of their prosthetic treatment and their satisfaction with prosthetic treatment in an attempt to provide some information on the improvement of the quality of life related to oral health and the promotion of oral health. Methods : The subjects in this study were 250 people who received education in two different lifelong education institutions in the city of Busan. After a survey was conducted from May 23 to June 15, 2011, the answer sheets from 217 respondents were analyzed. Results : 1. As for the general characteristics of the respondents, the men(52.1%) outnumbered the women. Those who were in their 60 and up(47.5%) made up the largest age group, and the married people(65.4%) outnumbered the unmarried ones. By occupation, the company employees(20.3%) made up the biggest group. By education, the greatest group was high-school graduates(36.1%). By monthly mean income, the biggest group gained an income of 2.01 million won or more(36.9%). As to medical security, community-based insurance was most prevailing (36.9%). In terms of health promotion, the largest group worked out to stay fit(52.4%). 2. Regarding oral health knowledge, they had a good knowledge about the cause of dental caries(56.7%), but they weren't well aware of the right time for regular dental checkup(47.9%). In relation to oral health care, regular scaling wasn't prevailing(16.9%). 3. Regarding connections between the general characteristics and satisfaction with prosthesis, the less-educated respondents expressed significantly more dissatisfaction(p=0.015). By monthly mean income, those who had a smaller income were dissatisfied in general(p=0.028). Conclusions : The findings of the study illustrated that it's required to spread awareness of the importance of oral health among people in general, and that differentiated incremental oral health care should be provided for different age groups. In order to raise the satisfaction of patients with prosthesis, how to relieve their pain and anxiety and how to adjust prosthetic treatment cost properly should carefully be considered. In addition, the government should take measures to offer assistance for the low-income classes in preparation for an increase in the elderly population.

The purpose of this paper is to present the potential application of tissue adhesive in the management of traumatized gingival wound in clinical dental hygiene practice. Cyanoacrylate adhesive has been used for closure of superficial laceration without suturing, which is available in periodontal and oral surgery. Small gingival or mucosal lacerations may occur by improper or excessive instrumentation of the dental hygienist during scaling and root planing procedure. In this circumstances, tissue adhesive is very effective, simple, and convenient method as an alternative to conventional wound closure by suturing. The tissue adhesive consists of monomeric n-butyl-2-cyanoacrylate, which polymerizes quickly in contact with tissue fluid. The sutureless treatment of gingival laceration with tissue adhesive has advantages of good esthetic results, less trauma, time saving, antibacterial and hemostatic effects. In addition, local anesthesia as well as re-visit for dressing and removal of suture are not required. Use of tissue adhesive could be beneficial to both dental hygienist and patient in the management of procedural error.

The objective of this study was to assess the level of contamination of dental equipment surfaces by Staphylococcus aureus and to obtain basic information for the prevention against cross infection between students and outpatients. Human samples were collected by rubbing the oral cavity, anterior noses, and lip of students and outpatients with sterile cotton swabs. Environmental samples were collected from 11 sites at practical laboratory, 4 sites at seminar room, and 5 sites at sterilizing room before, during, and after clinical procedures. These samples were cultured on brain-heart infusion agar at $37^{\circ}C$ for 24 hours. Gram-stained and identified as S. aureus colonies were counted each period and these results were analyzed by t-test and ANOVA test. In human, oral cavity showed the greatest S. aureus counts and there were no statistically significant differences between students and outpatient. Practical laboratory revealed the greatest S. aureus among all environmental groups. The greatest number of S. aureus was observed during clinical procedures (P < 0.05) and light handles, chair head, and spittoon showed a high level of statistically significant differences. In conclusion, S. aureus was dispersed in human and dental clinical environment and increased their number during clinical procedures.

The aim of this study was to analyze in depth the standardized Clinical dental hygiene curriculum of the Fones School in the United States. We investigated the clinical dental hygiene curriculum in 2015~2016 including title, credit, hours, contents, goals, competencies, and evaluation. We obtained the course syllabus and data related to each subject, for each grade, from the professors and students at the university. The goals and competencies, of the clinical dental hygiene program, which were based on the goals of the Fones School and the mission of the University of Bridgeport, were developed in accordance with the dental hygienist practice standards proposed by the American Dental Hygienists Association. The curriculum consisted of theory to teach proper dental hygiene care procedures and incorporated practical exercises that modeled an actual clinical setting. The students had to document the procedures performed for each client/patient and improve their clinical competency through discussion with the professors. Dental hygiene care should be provided for children, adolescents, adults, elderly, and patients, which includes patients with moderate or severe periodontal status. Students were evaluated by a paper test or case study presentation and their clinical evaluation was based on their clinical competency. In particular, professors evaluated students on a rotational basis, so they could evaluate the level of achievement of clinical competency of all students and find ways to improve any weaknesses. Therefore, the current study suggested that clinical dental hygiene program in Korea could be improved if based on the curriculum of Fones School in the United States.

This study analyzed the oral status after recording the images by using QLF-D with targets of 38 youth people with hearing impairment and hearing language impairment. In order to investigate the state of oral hygiene, plaque index (O'Leary index) and contents of investigation of the state of the teeth included the number of sound teeth, the number of caries teeth, dental caries experience and the number of filling teeth. The following results were obtained. First, women lacked the management on plaque and had more caries teeth compared with men. In terms of impairment classification, subjects with both hearing and language impairment lacked the management on plaque and had more caries teeth. Second, subjects who did not get an oral exam for one year had more caries teeth. Oral hygiene score was the highest with the brushing time for 3-4 minutes. The number of sound teeth was increased as the brushing time was increased. In addition, the oral hygiene management time was the highest when cleaning the teeth, gums and tongue at the same time. Third, it was shown that the satisfaction of oral health education by using the new equipment was high. As a result of this study, in order to improve the oral health level of impaired students, they shall be trained to manage their teeth by themselves and educated to increase their motivation and practice. Thus, it is thought that various approaches which are differentiated from existing methods are required to be tried.
