The purpose of this study,was to find out health status, characteristics related to working conditions, occurrence of low back pain and its related factors among dental hygienists working in dental clinics, and, thus, to provide basic information necessary to set up some plans for preventing the occurrence of low back pains and improving working conditions for dental hygienists. The data were collected from 310 dental hygienists working at dental clinics in Pusan and Kyungnam area, including Masan, Changwon, Jinhae and Jinju, with a self-administered questionnaire and were analyzed finally for 295 records with SPSS for Windows(7.52K) program. The results were as follows : Working condition was considered to be fair by 562% of dental hygienists were thought to threaten their health in the dental clinics. About seventy percent of dental hygienists worked over ten hours a day and 72.8% were standing while working over 7 hours, 65% considered working hours too long. Health status was thought be more than average for 82.3% while more than half perceived certain degree of stress frequently. The rate of complaining low back pains among dental hygienists was 87.8% with pains more than medium level for 39.3%. The variables significantly related to the degree of low back pains were height, uncomfortable postures, type of working postures and the height of working table, while some variables including height, hours of working on the feet, the presence of hazardous work environment, uncomfortable postures, the presence of hazardous works, the amount of working hours, type of working postures and work-associated stresses, were significantly related to the number of symptoms for low back pains. Multiple regression analysis showed that occurrence of low back pains was significantly influenced by 5 factors such as subjective status of health, work-related stresses, the degree of perception to work environment, the degree of perception to the amount of working hours and age. In conclusion, it might be necessary to manage working conditions effectively by reducing working hours, making good postures while working and removing stressful conditions in order to reduce risk factors for the occurrence of low back pains among dental hygienists. Therefore good working postures, assignment of appropriate rest time and some programs for early detection, care and education of low back pains should be provided for the dental hygienists.

Critical thinking is a essential competency for dental hygiene education and practice. The purpose of this study was to examine critical thinking disposition between groups classified by GPA score in two dental hygiene educational program. A total 252 dental hygiene students responded. The study extracted six dimensions(intellectual eagerness/curiosity, prudence, healthy skepticism, intellectual integrity, objectivity, self-confidence) derived from 27 items with the exception of systematicity using factor analysis. The mean score for critical thinking disposition was 3.47 on a 5 point scale. The result showed a statistically significant correlation critical thinking disposition and age. Multivariate analysis of covariance(MANCOVA) was used to compare six subscales between the three groups. MANCOVA results revealed that intellectual eagerness/curiosity for three groups were significantly different(Wilks's lamda=0.914, F(6, 24)=1.869), p=0.01, partial eta square=0.044). Multiple comparison for intellectual eagerness/curiosity by Scheffe's method showed differences between high score group and mid score group(p=0.027), high score group and low score group(p=0.002). In this study, academic achievement and critical thinking tends to show significant correlations is known. Critical thinking skills by examining the actual grade compares the difference in propensity scores according to a case study in intellectual curiosity, passion, and could tell the difference to appear.

Objectives : The purpose of this study is to arrange basic data necessary for education of AIDS and to prevent AIDS on undergraduates' knowledge or attitude toward AIDS. Methods : A self-administered questionnaire survey was used among 350 undergraduates in some of Jeonbuk and Gyeongnam area from September 9, 2009 to December 10, 2009 and then obtained the following results. Results : 1. Information route on AIDS was indicated to be higher in order of school education with 37.1% and TV & newspaper with 31.5% as for the health-related department. The health-unrelated department was indicated to be the highest in TV & newspaper with 67 people(43.8%), and had statistically significant difference(p<0.01). 2. The whole knowledge score on AIDS was indicated to be $12.72{\pm}2.67$ for the health-related department, resulting having been higher than the health-unrelated department with $11.84{\pm}3.30$. There was significant difference(p<0.01). The attitude score on AIDS was indicated to be $4.85{\pm}1.67$ for the health-related department, resulting having been higher than the health-unrelated department with $4.38{\pm}1.58$. There was significant difference(p<0.01). 3. Knowledge and attitude toward general AIDS stood at r=.112(p<0.05), thereby having had positive correlation. Knowledge and attitude toward AIDS infection stood at r=-.220(p<0.01), thereby having had negative correlation. Relationship between the whole knowledge and attitude toward AIDS stood at r=-.105(p<0.05), thereby having had negative correlation. Conclusions : AIDS is exponentially increasing in the whole world and is getting more serious. Even in our country, it is the tendency that the infected are gradually increasing. Health care of AIDS, which is impossible to be fully recovered and has no vaccine, is preferential to prevent infection. A continuous and efficient preventive education program is thought to be necessary for straightening wrong knowledge and prejudice on this by grasping right knowledge and attitude toward AIDS.

Objectives: To analyze the association between sleep duration and the number of remaining teeth in people aged 65 years or older in order to provide basic data for improving sleep quality and developing oral health programs for teeth maintenance. Methods: The raw data for the analysis were obtained from the sixth Korean National Health and Nutrition Examination Survey (KNHANES) dataset, conducted between 2013 and 2015. The 4,340 subjects included in the study underwent oral examinations and then proceeded to answer related questions. The collected data were analyzed using SPSS (ver 23.0) program via composite samples, with the calculations for mean, standard deviation, chi-square test, and logistic return analysis being performed. Results: An analysis of the effect of sleep duration on the number of remaining teeth among people aged >65 years old showed that if the confounding variables were not corrected for, the risk of having less than 9 hours of sleep was 1.40 times higher (95% CI: 1.06-1.86). However, this was not statistically significant in models that corrected for gender, age, and other confounding variables (p>0.05). Conclusions: The association between sleep duration among the elderly with their number of remaining teeth was confirmed. Therefore, measures to improve sleep quality and oral care practices to maintain the remaining teeth in people over 65 years old should be developed.

Objectives : This study aims to improve health and the quality of life of teenagers by identifying an association between the periodontal status and oral health behaviors of Korean teenagers using 2010 Korean National Oral Health Survey data. Methods : Subjects were teenagers aged from 12 to 15 in Korean National Oral Health Survey (KNOHS). The questionnaire consisted of periodontal status, general characteristics, periodontal related factors, and oral health related behaviors. Results : Gingival bleeding was found in 56.9% of teenagers because unhealthy periodontal status and tartars were found. Those who were 15 years old had unhealthier periodontal status than those who aged 12 years old. Those who lived in rural areas tended to have worse periodontal status than those who lived in the big cities. Access to dental floss, mouth rinsing solution and regular dental checkup tended to make the healthier periodontal status. Smokers had the worse periodontal status than the nonsmokers. Conclusions : The oral health care in the teenagers aged from 12 to 15 is very important because the permanent dentition is completed in this stage. It is necessary to lay emphasis on the oral health improvement and dental caries prevention program to the teenagers.

Objectives: The purpose of this study was to compare the differences in oral health-related quality of life among elderly people aged over 65 years, in terms of physical, mental and oral health status and to analyze factors affecting their oral health-related quality of life. Methods: From May 9 to June 23, 2017, we randomly visited aged-care community centers in the metropolitan area, and recruited 222 elderly, aged 65 or older. First, each participant completed a questionnaire consisting of 4 general items: 1 systematic disease, and 3 subjective oral conditions. Afterwards, the researchers interviewed the participants to assess their mental status, using MMSE-DS and recorded the responses. Finally, an oral examination was performed to determine the number of remaining teeth. The average oral health-related quality of life according to each characteristic was analyzed by t-test and ANOVA. Hierarchical multiple regression analysis and Pearson's correlation coefficient analysis were used to analyze the correlations between factors and the factors affecting oral health-related quality of life. Results: The mean oral health-related quality of life was 4.15. Participants with 20 or more remaining teeth demonstrated better oral health-related quality of life than those with 19 or less teeth. Higher oral health-related quality of life was also found among elderly without gingival bleeding, self-reported halitosis and dry mouth. In addition, positive correlation with the number of remaining teeth and negative correlation with gingival bleeding, self-reported halitosis and dry mouth, were noted. Finally, the results of the hierarchical multiple regression analysis indicated that remaining teeth, gingival bleeding, self-reported halitosis and education were influential factors in determining the oral health-related quality of life among the elderly. Conclusions: The results of this study confirmed the necessity of better policy support, and the importance of implementing delivered, elderly-centered oral health education program by professionals to prevent tooth loss and manage periodontal diseases.

This study set out to analyze the relationships between the senior citizens' dental health activities and dental health conditions, to provide basic data to develop a program for their better dental health, and finally to search for the ways to improve their life quality through dental health care. The subjects were 142 senior citizens(58 were male and 84 were female) who were 65 years old or older and visited a dental hospital or clinic in the Seoul metropolitan area from April 17 to April 28, 2006. With the cooperation from the dentists, the investigators examined their dental conditions and conducted one-on-one interviews to collect the information about their demographic characteristics, dental health activities, and subjective dental health conditions. The collected data were analyzed with T-test, ANOVA and Pearson's correlation coefficient using the SPSS WIN 11.5 program. The analysis results were summarized as follows: First, 58 men(40.8%) and 84 women(59.2%) consisted of the subject group, where percentage of the female participants was bigger Those who were aged from 65 to 69 made the biggest age group in the subjects, accounting for 58.5% with 83. Second, those who had three dental caries or less and then didn't treat them or treated them(F) accounted for the biggest percentage with 117(82.4%) and 72(50.7%) respectively. As for the remaining teeth, the biggest number of them(40 subjects, 28.2%) had three or less remaining. Third, it turned out the female subjects had a higher level of dental health activities than their male counterparts(P = 0.00). As for living expenses, those who were paid salary or earned income themselves carried out their dental health activities in a higher level than those who lived on the benefit from the government(p = 0.02). Fourth, the subjects' subjective dental health conditions had negative correlations with their dental caries not treated. And there were positive correlations between their dental caries not treated and dental caries lost and between their dental caries treated and remaining teeth. Fifth, those subjects who earned their living expenses themselves had the most dental caries treated at 5.4(p = 0.02), and there was statistically significant difference with the numbers. Sixth, those subjects who brushed their teeth in their own manner had 11.8 teeth lost(p = 0.05), which was more than the number of those who brushed their teeth in other methods. And there was statistically significant difference among them. The remaining teeth were found most at 17.3(p = 0.00) among those who brushed their upper and lower teeth separately. In addition, those who visited the public health center often had significantly more teeth treated(4.3) than others(p = 0.00).

The purpose of this study was to examine the correlation of oral health behavior, oral health state and PHP in an effort to facilitate the promotion of oral health and improve oral health care. The subjects in this study were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S college dental clinic from September 5 to December 1, 2007. The collected data were analyzed with SPSS WIN 12.0 program. The findings of the study were as follows: 1. The younger patients had a smaller number of FT index, and the older patients excelled the younger ones in oral health behavior involving the use of oral hygiene supplies, regular visit to dental clinics and dietary control. 2. The patients got 2.62 out of possible five points on oral health behavior, which indicated that their oral health behavior wasn't good enough. Those whose oral health behavior was better had a smaller number of DT index and a larger number of FT index. A better oral health behavior led to a lower PHP index. 3. There was a negative(-) interrelationship between oral health behavior and DT index, and oral health behavior had a positive(+) correlation with FT index. The oral health behavior had a negative(-) correlation to PHP index, which showed that a better oral health behavior led to a lower PHP index. The above-mentioned findings seem to suggest that oral health behavior is one of integral factors to affect oral health status and PHP index, and the kind of oral health education that could change oral health care attitude should be provided during scaling practice after grasping the actual oral health behavior of patients.
