Objectives: The purpose of this study is to investigate the effects of oral health practice in living rehabilitation schools for disabled residents. Methods: A total of 110 questionnaires were used for analysis by randomly selecting six residential facilities for the intellectually disabled in Gyeonggi-do and conducting a self-written questionnaire to a life rehabilitation teacher. Results: As a result of analyzing the correlation between age, career, oral health knowledge, practice, and environment of life rehabilitation teachers, it was found that there was a positive. correlation between career, oral health knowledge, oral health practice, and oral health environment. As a result of confirming the factors that influence the oral health practice of life rehabilitation teachers, oral health knowledge (β=0.527 p<0.001), oral health environment (β=0.214, p=0.050). Was found to be related to oral health practice. Conclusions: There is a need to provide continuous oral health education and oral health environment in residential facilities so that life rehabilitation teachers can practice oral health.

Objectives. The purpose of this study was to evaluate the effect of dental erosion by some commercial beverages on sound enamel of bovine teeth using confocal laser scanning microscopy (CLSM). Methods. Three experimental groups (mixed beverage, carbonated flavored, and fruit juice) and one control group (natural mineral water) were established for this study. Each group consisted of 11 specimens obtained from bovine teeth. The concentration, pH level, fluoride, Ca and P of beverages were measured. Specimens were immersed in artificial saliva, except beverage treatment for day 8, and surface microhardness and lesion depth were measured. Results. The pH level of the four beverages was in the range of 2.39∼7.60. The concentration levels of fluoride, Ca and P were in the range of 0.03∼0.16 ppm, 1.67∼9.07 mg per 100 gm, and 0∼3.73 mg per 100 gm, respectively. The differences in surface microhardness (VHN) before and after the 8 day treatment were significant among the four groups for sound enamel. Lesion depths after the 8 day treatment on sound enamel by CLSM decreased significantly in of the following order: mixed beverage, carbonated flavored, fruit juice and natural mineral water (p<0.01). Lesion depths by CLSM correlated with surface microhardness using the surface hardness test on sound enamel (r=?0.920). Conclusions. In this study, beverages with rich Ca and low pH showed lower VHN and lesion depth. Thus, we propose that low pH beverages with rich Ca may reduce the extent of dental erosion on sound enamel.

The purpose of this study was to examine dental hygiene students` achievement motivation and factors affecting dental hygiene students` achievement motivation by the general characteristics of subjects in this study. The subjects in this study were 450 who were selected by convenience sampling from three different three-year-course colleges. After a survey was conducted, the answer sheets from 421 respondents were analyzed. The collected data were analyzed, which made use of t-test, ANOVA and Kruscal-Wallis test. The findings of the study were as follows. 1. The dental hygiene students investigated got 3.34 in achievement motivation. They got the highest score of 3.78 in the item ``I perform what I have to do with a sense of responsibility.`` and they got the lowest score of 2.67 in the item ``I like to do something risky.`` 2. Concerning links between their general characteristics and achievement motivation, the students whose academic year was higher(p<0.001) and who had more clinical practice experiences(p<0.01) were better motivated than their counterparts. As to connections between achievement motivation and expected post-graduation length of service, those who replied that they planned to find another job after getting married were better motivated(p<0.05). Regarding relationship between achievement motivation and a will to work abroad, the students who had a stronger will to work abroad were better motivated. 3. As a result of checking the influence of their general characteristics on achievement motivation, stronger motivation was found among the students whose academic year was higher(p<0.01), who intended to work until marriage(p<0.01) and who didn`t plan to keep working after marriage(p<0.05) when the other variables were controlled. Therefore dental hygiene students should be taught to look at things positively when they enter college, and they should also be educated to become progressive to keep working for their lifetime instead of just getting a temporary job after graduation.

This study was conducted to assess macro- and micronutrient compositions in school lunch menus based on the ``Dietary Guideline`` for School Lunches. Ninety-five dieticians in elementary school in Chungbuk were asked to complete a questionnaire on characteristics of the school lunch program (such as type of foodservice, food production system), the information about dietitians (such as age, education, and job history), and the extent of the use of processed foods and frozen foods. They were asked to return the questionnaire with the menus including the name and the quantity of every food ingredient offered during a week. A total of 554 lunch menus provided for a week of June 2004 were analyzed. Average nutrient content per meal was as follows; 660 kcal, energy; 92.9 g, carbohydrate; 26.7 g, protein; 21.1 g, fat; 287 μgRE, vitamin A; 0.5 mg, thiamin; 0.5 mg, riboflavin; 29.3 mg, vitamin C; 338.2 mg, calcium; 3.9 mg, iron; and 97 mg, cholesterol. Average percentages of energy from carbohydrate, protein and fat was 56.2%, 16.2%, and 29.0%, respectively. The mean nutrient content per meal was higher in rural-type than in urban-type schools. The weekly menu of 40% of the schools provided < 55% of energy from carbohydrate, and 39% of the schools offered lunch that provided ≥ 30% of energy from fat. The micronutrient content was generally high when the percent energy from fat was less than 25%. Our results showed that only 52.6% of the schools provided lunches with the energy composition as in the ``Dietary Guideline`` of School Lunches. Whole Milk was the major contributor to fat, saturated fatty acid and cholesterol. We suggest that school foodservices start to provide low fat milk instead of whole milk to reduce fat, saturated fatty acid and cholesterol. If low fat milk is served instead of whole milk, percentage of energy from fat and saturated fat can be reduced from 29% to 25%, and from 10.2% to 9.1%, respectively, and cholesterol could be reduced from 97 mg to 79 mg. Efforts to meet ``Dietary Guideline`` for School Lunches should be made, especially to reduce fat intake, while maintaining essential nutrient intake at sufficient levels for childen.

Objectives : The purpose of this study was to examine what image dental hygiene students had about a dental hygienist during clinical practice and what factors affected their image of dental hygienist. Methods : The subjects in this study were the dental hygiene students at three different colleges. After a survey was conducted, the answer sheets from 427 respondents were analyzed. Results : The dental hygiene students who had engaged in clinical practice had a higher self-esteem than those who hadn`t in general(p<0.01). A statistically significantly stronger achievement motivation was found among the dental hygiene students who had engaged in clinical practice than those who hadn`t(p<0.01). The dental hygiene students who had engaged in clinical practice had a statistically significantly worse image of a dental hygienist than the others who hadn`t(p<0.01). Whether the self-efficacy, self-esteem and achievement motivation of the dental hygiene students had any impact on their image of a dental hygienist was analyzed in consideration of their clinical practice experience. As a result, the dental hygiene students who had engaged in clinical practice had a more positive image of a dental hygienist when they had a higher self-esteem(p<0.05) and a stronger achievement motivation(p<0.001), and those who hadn`t engaged in clinical practice had a more positive image of a dental hygienist when they had a higher self-esteem(p<0.01). Conclusions : Given the above-mentioned findings, a wide variety of programs should be developed to bolster the self-esteem and achievement motivation of students and improve their image of a dental hygienist, as self-esteem and achievement motivation are the variables that exert the largest influence on one`s image of a dental hygienist.(J Korean Soc Dent Hyg 2012;12(4):781-792)
