The purpose of this study is to evaluate the behaviour and awareness about oral health of pre-school teachers and to develop the oral health program for pre-school children. From september to april in 2005, we surveyed 120 pre-school teachers in total of 41 pre-school in H city with self-recorded questionnaire. Data analysis was carried out using the SPSS Ver 11.5 program. The findings of this study were as follows : 1. The proportion of the pre-school teachers who have taken oral health program increase as teacher’s age increase(p＜0.05). 2. The brushing is best method of the children to prevent their teeth. 3. The children in most pre-school did not brush their teeth after a light meal. Especially, this tendency increase as the size of pre-school is increasing(p＜0.05). 4. The pre-school where the size is big, executed a periodical screening dental examination(p＜0.05). 5. The pre-school teachers have insufficient knowledge about oral health care. 6. The children in most pre-school did not go the dental clinic the last year. 7. Therefore, it is necessary to develop the oral health program for the pre-school teachers.

Objectives: The purpose of this study was to provide the basic data for preventing dental caries, and maintaining and enhancing oral health soldiers. Methods: The subject of this study through the survey of the recognition of oral health, a questionnaire survey was conducted for 120 male soldiers. Statistical analysis was conducted using the SPSS 12.0 with t-test, ANOVA, and x2 -test. Results: The level of oral health knowledge was generally high but showed no statistical significance with age, education, smoking, and drinking. The younger, the less soldiers visited a dental clinic for the purpose of prevention (p=0.015). In case of 26-35 years old group and over college graduate group, the ratio of scaling experienced was significantly high (p=0.027, p=0.036). Conclusions: The findings suggest that oral health education program such as on the use of fluoride and sealants should be developed.

Objectives: The purpose of this study was to investigate on the recognition of preventive effects about dental caries who were employed in Gyengsangnam-do, Korea. Methods: The data obtained from 330 dental hygienists during 2 month. The survey was performed by a face-to-face interview questionnaire. The respondents were 315 from dental hygienists. Data were analyzed using frequency distribution, ANOVA. All statistical analyzed were conducted using Statistical Package for SPSS 11.5. Results: Dental hygienists thought that fluoride had preventive effects about dental caries. They thought pit & fissure sealants were effective in the prevention of dental caries. Conclusions: The findings suggest that oral health education program such as on the use of fluoride and sealants should be developed.

The purpose of this study was to examine the musculoskeletal pain management of dental hygienists in a bid to pave the way for the development of programs geared toward letting them lead a healthier life at work. The subjects in this study were dental hygienists who worked in dental hospitals and clinics in Seoul and Gyeonggi province. A survey was conducted by visiting them from July 9 through August 24, 2007. The findings of the study were as follows: 1. Concerning the state of musculoskeletal pain, 41.3 percent of the dental hygienists investigated felt that pain before they started to work as dental hygienists, and 94.2 percent suffered that pain after that. 2. As to the cause of musculoskeletal pain, treatment posture(67.5%) was cited as the cause, and another cause was that they had to stand for a long time(23.5%). 3. After they worked at dental hospitals or clinics, they felt significantly more musculoskeletal pain in the neck(p＜.05) and on the shoulder(p＜0.01), and they had a backache significantly more as well (p＜0.01). 4. As for the way of handling the pain, the largest group(33.6%) just bore with it. The second greatest group took physical therapy(26.3%), followed by Oriental medical treatment(14.7%), selftreatment(14.3%) and drug intake(8.5%). 5. Regarding connections between musculoskeletal pain experience and life adjustment, those who had ever felt that pain after starting to work in dental hospitals or clinics(3.44±.667) were less adjusted to daily routine life than the others who hadn’t(4.00±.667)(P＜0.05). And the former fitted into their workplaces less(3.09±.568) than the latter. The gap between the two was statistically significant(P＜0.01). 6. The dental hygienists who suffered pain due to the repetitive use of the body(2.98±.854) were less adjusted to daily routine life and work than the others who didn’t(3.73±.767)(P＜0.001). 7. As for correlation between the pain experience and difficulties at work and in daily life, those who felt the pain found it hard to take care of their work, and were aware of the necessity of health checkup. But the pain experience didn’t have a close correlation to their awareness of the necessity of health checkup(P＜0.01). The dental hygienists who faced difficulties in daily life found it hard to handle their work as well, and those who were cognizant of the necessity of vocational health education were more in want of education about how to alleviate the pain. There was a strong correlation between their awareness of the necessity of vocational health education and their need for education about how to ease the pain. 8. In regard to health checkup, 48.8 percent underwent a health checkup once a year at work. 37.8 percent had never done it on a regular basis, and 90.7 percent felt the need for that.

An extended life span has made people in general pay more attention to the importance of health and oral health as what affects the quality of life, and that also has contributed to having their health-related financial burden and pain compounded. The subjects in this study were adults who were under 65 across the nation in Western age. They were selected by using a table of random numbers from a KTF directory, and a self-administered survey was conducted by mail from March through June, 2006. The collected data were analyzed with SPSS/PC WIN 12.0 program. The major findings of the study were as follows: 1. As for the reliability of SF-36, an inventory of evaluating the quality of health-related life, Cronbach’s alpha of it ranged from 0.7 to 0.9. Concerning the reliability of its oral health-related life, Cronbach’s alpha of it was between 0.8 and 0.9, which indicated that the instrument was highly reliable. 2. Concerning relations between their oral health state and the quality of life related to general health and oral health, a higher quality of life was led by those whose occlusal conditions were normal, whose dental calculus was less and who had a less number of missing teeth and prosthetic tooth. And the gap between them and the others was statistically significant. Missing teeth made a difference to the quality of life related to oral health by approximately 12 to 15 scores when the rate of missing teeth accounted for 30 percent or less. The number of prosthetic teeth made little difference to the quality of life, but the denture wearers were different from the others in the quality of life related to oral health by about 17 to 29 scores. 3. As for connections between oral health state and the quality of life related to general health, those whose occlusal conditions were normal were in good shape, and dental calculus was closely tied into general health in five subcategories except for that of physical pain. Missing teeth made a difference by about 12 to 15 scores to the quality of life related to general health, except for vitality and mental health, when the rate of missing teeth represented 30 percent or less. 4. Regarding connections between the general characteristics of the subjects and their quality of life related to general health and oral health, those who were male, who were younger, who were better educated and who had a larger monthly mean income, led a higher-quality of life in association with general health and oral health. And the gap between them and the others was statistically significant. 5. Their gender had the biggest impact on their quality of life related to general health, followed by age, the number of prosthetic tooth, the number of missing teeth and monthly mean income. Their quality of life related to oral health was under the greatest influence of age, followed by gender, monthly mean income, the number of missing teeth, the number of filled teeth and the number of decayed teeth. The influence of all the factors was statistically significant. 6. Concerning relations between the quality of life related to oral health and that related to general health, those whose oral and general health scores were both above 80 made up 60.5 percent of the subjects. The higher quality of life related to oral health was concurrent with the higher quality of life related to general health, and investigating into the former is one of useful ways to find out about the quality of life related to general health. The above-mentioned findings lent credibility to the reliability of the Korean versions of SF-36 and OHIP-49. One’s health cannot be complete without a good oral health, and the quality of life definitely hinge on oral health status. So the importance of existing teeth shouldn’t be overlooked. Intensive research efforts should be directed into providing successful health education for different group of learners to improve their quality of life, and a larger number of subjects from different backgrounds should be examined to prepare more valid instruments. Improved health education is expected to promote the health of people, to let them stay away from diseases and to help them live a better quality of life, and efficient health-care policies should be prepared to urge them to keep taking care of themselves.

This study aimed at examining the current establishment and operation of the Picture Archiving and Communication System (PACS), which is a sub-system of the Hospital Information System (HIS) and evaluating effects of hardware functions on satisfaction, difficulty, and convenience. Data were collected by using structured questionnaires with dental hygienists currently working at dental clinics which introduced PACS in Seoul and Gyeonggi Province. A total of 232 dental hygienists from 20 clinics participated in the survey. Many subjects answered that they had no idea of the Digital Imaging and Communications in Medicine (DICOM 3.0); there were many dental unit chair attachment types in terms of monitor establishment; imaging data were usually stored indefinitely; and check was performed irregularly by AS businesses. Imaging was mainly transmitted to other clinics via storage in CD or e-mail; PACS was found to be generally effective in terms of attitudes toward the system; what was the most urgent improvement was found to be stability of programs. The easier the photographing function, the higher convenience evaluated; the easier error correction for patient information and imaging and the better quality of screen, the higher satisfaction and difficulty evaluated. Evaluation of hardware and software was found to have positive effects on satisfaction and convenience. This study will significantly provide reference data for dental clinics intending to introduce PACS and companies producing the system to construct a high-efficiency system.

This study is to know the determinants that influence teeth’s health recognition of adults in Jeju areas. A result of this study comes from an analysis on basis of a survey composed of adult respondents. 1. Regarding the general characteristics, this study shows that there is a high relationship between sex and dental caries. However, this study does not indicate that there is a statistically significant relationship between age and jobs and dental caries. 2. Regarding a study of a relationship between general characteristics such as sex, age, and job and a regular teeth examination, this study is not statistically significant. However, a relationship between teeth’s frequency on teeth health recognition and sex is statistically significant. Regarding an experience to visit dental clinics, 95 males (72.5%) respond that they do not visit dental clinics and 88 females (73.9%) respond negative answers for the experience to visit dental clinics. A study of an experience to remove calculus is not statistically significant. 3. A study regarding a relationship between age and the teeth frequency and an experience to visit dental clinics is not statistically significant. However, a study between age and an experience to remove teeth calculus is statistically significant. This study shows that 30 respondents (19.6%) of less than 29 years old the most highly have an experience to remove teeth calculus. 4. Regarding a study for a relationship between jobs and teeth health exercise in teeth health recognition, the case of a frequency of teeth brush, an experience to visit dental clinics, and an experience to remove teeth calculus is statistically significant. 5. This study shows that there is a statistically significant relationship between an existence and non existence of dental caries and a regular teeth examination in the teeth health recognition.

The present study is designed to discover the relationship between the cognizance level of dental hygiene and its practices in order to prepare more effective precaution methods of oral diseases by surveying 518 high school students in the Kyunggi province. When analyzed with SPSS(version 12) for frequency analysis, ANOVA, and t-test, the survey shows; 1. In general, over 85% of the surveyees are in the 1st and 2nd grades with similar sex ratio patterns. The majority(47.4%) of the surveyees’parents are 45-49 years old and highschool graduated(49.8%). 2. Dental hygiene practices hardly seem to be related with the surveyee’s education and sex(p=0.842). The parents’age and education only show difference depending on the variables with no statistical meanings. 3. The subjects recognizing the need of education show statistically meaningful difference(0.000) with high dental hygiene knowledge points. 4. The subjects individually thinking they maintain sound oral conditions show statistically meaningful difference(p=0.040) in high dental hygiene practices. 5. It indicates that males show higher interest(2.90) in participating in the school dental hygiene orientation than females(2.86) and most show average interest in the school dental hygiene.

The purpose of this study was to examine what factors affected the smoking knowledge and attitude of junior college students in some area of Gyeonggi province, as the rate of smokers was high among college students. The subjects in this study were all the male and female freshmen, sophomores and juniors in a junior college. Data were gathered for seven days from June 5 through 12, 2006, by conducting a survey. After assistants were explained about the purpose of the study to ask for their help, the survey was conducted by visiting the college. 600 questionnaires were handed out, and the answer sheets from 568 students were gathered, which showed the response rate stood at 94.7 percent. The findings of the study were as follows: First, by gender, the rate of the male students who smoked a cigarette or more everyday was far larger than that of the female students who did(p=.0001). Second, by academic year, the sophomores made up the largest group that was smoking a cigarette or more everyday, followed by the freshmen and juniors(p=.0001). Third, in terms of the impact of families, the students who were smoking a cigarette or more a day were under the most influence of the rate of smokers among their siblings(p=.0001). Fourth, concerning connections between the current smoking state and smoking attitude, those who had never smoked responded to smoking in a very negative manner, and the students who smoked but not everyday responded to that in a less negative way(p=.0001).

The osseointegration rate of titanium dental implants is related to their composition and surface roughness. Rough-surfaced implants favor both bone anchoring and biomechanical stability. There are many different methods which used for increasing surface roughness or applying osteoconductive coatings to titanium dental implants. Surface treatments, such as titanium plasma-spraying, grit-blasting, acid-etching, anodization or calcium phosphate coatings, and their corresponding surface morphologies and properties are described. Most of these surfaces are commercially available and have proven clinical efficacy (＞95% over 5 years). The precise role of surface chemistry and topography on the early events in dental implant osseointegration remain poorly understood. The future of dental implantation should aim to develop surfaces with controlled and standardized topography or chemistry. This approach will be show a way to understand the interactions between proteins, cells, and implant surfaces. The present work assesses the effect for cell attachment according to different implant surface patterns; smooth surface, anodic spark deposition and Sandblast large grit acid etching. The cell attachment on the surface which was created by anodic spark deposition method is more favor comparison with other two type of surface.

As the economic level improves with the dietary habits changing, we need to be reaware of the oral hygienics, while an oral hygienic education program is urgently required for correct oral hygienic behaviors. With such basic conceptions in mind, this study was aimed at testing the correlations between ordinary people’s belief thereof and their oral hygienic behaviors and thereupon, providing for some basic data useful to correct guidance of ordinary people’s desirable oral hygienic behaviors, emphasis on need and importance of an oral hygienic education, designing and implementing of adequate oral hygienic education programs. For this study, the researcher sampled each district from 4 spheres of Seoul (eastern, western, southern and norther spheres) and then, resampled 2 dongs (unit administrations) from each district, and thereupon, divided their residents aged between 20 and 49 into age groups at the intervals of 5 years. Thus, the researcher personally visited the areas where it would be deemed most probable to meet the subjects people most evenly distributed by age group to conduct a questionnaire survey from February 8 through March 28, 2006. In this course, the researcher attempted to sample the subjects from the job groups as much diversified as possible, while abstaining from sampling more than 4 or 5 people from the same area, in order to maintain an effective representation of the sample. Out of 1,885 people sampled, 1,178 subjects responded to the survey, and the final sample of 1,014 responses excluding those insincere one was used for the analysis. The questionnaire consisted of a total of 61 question items; 31 items, which were prepared by modifying and complementing Oh Yun-bae’s scale of subjective oral hygienics, could be categorized into 6 groups (perceived sensitivity, seriousness, impediment, usefulness, self-efficacy and motivation). 25 items were about oral hygienic behaviors (dental treatment, removal of odontolith, regular dental check, teeth-brushing methods, dietary habits, smoking and drinking habit, harmful oral habits, etc.), and 5 items were about subjects’demographic variables (gender, age, marital status, academic background and job). The collected data were encoded to be analyzed using the SPSS Windows 10.0 for frequency analysis of subjects’demographic variables, Chi-square test, T-test, ANOVA and multiple regression analysis of subjects’knowledge of oral hygienics, their belief in oral hygienics and their oral hygienic behaviors. The significance levels were determined by means of Chi-square test. The results of this study can be summarized as follows; 1. Wes survey all ages were very high ‘perceived usefulness’it was to belief in oral hygienics, the ‘motivation’were very low. Prevention of the oral cavity for behaviors a removal of odontolith and teeth-brushing methods, were high perceived usefulness as possible used to oral hygienics support supplies. 2. 53.7% of all respondents answered as“ average”for the question concerning oral hygienic condition. According as age increase, the frequency of visit a dentist increased as well, The respondents visited dental offices for regular removal of odontolith and treatment of decayed teeth. 3. The survey showed that dental floss is used most frequently as an oral hygiene supplement. In addition, 15.2% of all respondents received a regular odontolith removal (once a year) 4. The survey demonstrated that people in their 20s preferred sweets and snack, while all ages showed dispreferrence of hard and dry food in terms of eating habit. 5. In terms of smoking habit, the survey demonstrated that men are more likely to smoke for a longer period of time than women. 6. The survey showed that both male and female have harmful oral habit of‘ mouth-breathing’. As discussed above, it was confirmed through this study that ordinary people’s belief in oral hygienics were significantly correlated with their oral hygienic behaviors. That is, poorer belief in oral hygienics did not affect the desirable oral hygienic behaviors, but high belief in oral hygienics resulted in desirable oral hygienic behaviors.

For carrying out oral health service performance harmoniously, many elements are needed. Also, for efficiency, profitable information must be collected and conjugated. In this study we analyzed for the factors of oral health service performance and configuration and collecting of information. Questionnaire survey was posed to 90 dental hygienists working in health centers and health sub-centers. The obtained results were as follows; 1. Most respondents thought that the potential of charge and human power were most important in oral health service performance. And when the role assignment was practiced well and potential of charge was displayed well, oral health service performance was more practiced. Also, when human power was lacked, oral health service performance was no more practiced. 2. Collecting of information were more frequently used in a book and internet, and the location of collecting information was in Korean Dental Hygienists Association. 3. All respondents thought that information public ownership of oral health service performance was needed, and the most needed materials were education materials. 4. A large majority of respondents(70.2%) remarked that an information meeting of oral health service performance was not.
