In this study a survey was conducted with tenth, eleventh, and twelfth-graders in some academic and vocational high schools in Seoul, Gyeonggi Province, and South Chungcheong Province from April 3 to 30, 2009; then, 600 questionnaires returned were analyzed, obtaining the following results. It was found that there were some differences in subjective perception and behavior among some high school students by school type (p<0.001). This suggests the need to make systematic programs within curricula for oral health education and prevention programs that practically help to improve oral health.
This study aimed to develop a measure of professional identity for Korean dental hygienists and to analyze the factors and characteristics of professional identity of these dental hygienists. In this study, 890 dental hygienists completed a self-administered survey. The final analysis was conducted with a total of 880 responses, excluding 10 questionnaires with unreliable responses and partial responses. A systematic literature review was conducted to establish the definition of professional identity, while content validity, exploratory factor, confirmatory factor, and reliability analysis were conducted to establish the constructive factors. Descriptive statistics, independent sample t-test, and one-way ANOVA were used to identify the level of each factor. Authors conceptualized the professional identity for Korean dental hygienists and item generation, item reduction, and questionnaire formatting. The developed measure of professional identity for dental hygienists consisted of five factors, with 15 items. "Sense of calling," "need for academic capacity building," "performance of delegated authority," "compliance of code of ethics," and "usage of professional organizations" were the constituent factors. Based on these factors, the level of professional identity was the highest in the "performance of delegated authority" and lowest in the "usage of professional organizations." These finding indicated that dental hygienists with higher education levels have higher professional identity levels. The dental hygienists working at the general/university hospital had the highest level of professional identity. Thus, further research is needed to establish a model that consists of factors affecting and influencing the professional identity of dental hygienists.
Objectives : The purpose of this study was to examine the factors related to the dental caries and periodontal diseases of Korean elderly people in terms of demographic characteristics, oral health promotion behavior and systemic diseases in an effort to provide information on national policy setting and policy evaluation about the prevention of tooth loss resulting from severe oral diseases and the promotion of elderly people's oral health. Methods : The first-, second- and third-year raw data of the 4th National Health and Nutrition Survey were utilized, and the data of 3,882 elderly people who got a dental checkup were analyzed. The statistical package SPSS WIN 19.0 was employed to make a logistic regression analysis. Results : The senior citizens who did toothbrushing less frequently were more likely to have dental caries. As for periodontal diseases, the men were 1.34-fold more likely to have periodontal diseases than the women, and the respondents whose self-rated health state was worse were 1.40-fold more likely to have periodontal diseases than the others whose self-rated health state was better. The senior citizens who ever received treatment from unqualified people were 1.30-fold more likely to have peridontal diseases, and those who took neither vitamin compound nor minerals were 1.30-fold more likely to have periodontal diseases. Those who suffered from low High-density Lipoprotein cholesterol(HDL) were 1.35-fold more likely to have periodontal diseases than the others who didn't. Conclusions : Those whose self-rated health status is worse should especially be concerned about periodontal diseases. Specifically, it's needed to pay attention to the low-income classes, and the government should take measures to provide quality welfare services for elderly people not to receive treatment from unqualified people. Besides, research efforts should be made to determine the relationship between periodontal diseases and low HDL-cholesterolemia.
This study was conducted to analyze the impact factors of serious dental disease of elderly and to propose the need to treatments of negative factors on oral health-related quality of life. This study used the data of the 6th 3nd-year(2015) National Health and Nutrition Examination Survey. The dependent variables of this study were reviewed for serious dental diseases, and the independent variables were divided into demographic characteristics, health status and behavior, oral health status, and behavior. The results of study were as follow. Factors influencing dental caries was household income(p<.01), health checkups(p<.05), experience of toothache for the recent 1 year(p<.05), and whether to use oral hygiene devices(p<.05). Factors influencing periodontal disease was age(p<.05), occupation(p<.05), and whether to Comorbidity(p<.05). Based on these results, a political alternative plan will need to be arranged for promoting oral health in the aged as a relevant research is vitalized.
Background: Periodontitis is a chronic inflammatory condition associated with dysbiosis of the oral microbiota. The aim of the present clinical study was to explore the adjunctive effect of ozonized water irrigation in the circuits of ultrasonic scalers for the full-mouth decontamination of patients with periodontitis Stage I or II. Methods: The study was a randomized, single-blinded, parallel-group clinical trial. The test group (n=25) was treated with ultrasonic scalers irrigated with ozonized water, whereas the control group (n=25) received normal tap water irrigation within the ultrasonic scalers used during the professional mechanical debridement. Full mouth plaque score, bleeding score, probing pocket depth, and the gingival index were evaluated at baseline, two, and 4 weeks after treatment. The pain perceived and dental anxiety were also assessed after treatment by means of the visual analog scale (VAS). Results: All periodontal parameters resulted in significant improvement for both study groups. The effect of the treatment group on the gingival index was significant, in particular, patients in the test group experienced a greater reduction in this score. No significant differences could be observed with regards to the average probing depth, full mouth plaque index and bleeding score. Patients treated with ozonized water running in the circuits of ultrasonic scalers displayed also lower scores for pain and dental anxiety. Conclusion: The present study showed a significant clinical effect on gingival inflammation attributable to adjunctive ozone irrigation during nonsurgical periodontal therapy. Further studies, including patients with severe periodontitis and greater sample sizes, are recommended to test the clinical effect of ozonized water in the circuits of ultrasonic scalers.
Over expression of TGF-${\beta}1$ revealed the same phenotype as NFI-C deficient mouse. It has been reported that NFI-C deficient mice demonstrated abnormal odontoblast differentiation and aberrant dentin formation during root development. In the present study, in order to investigate the histological differences between wild type (WT) mouse and NFI-C deficient mouse, we compared morphological characteristics and smad4 expression between those mice. Hematoxyline-eosin (H-E) staining was used to investigate morphological changes and immunohistochemistry was also performed to observe the Smad4 expression pattern. In H-E staining, incisor of NFI-C deficient mouse showed an open area in the lingual root, irregular odontoblasts and osteodentin. Also, NFI-C deficient mouse showed short root and osteodentin in molar. In addition, Smad4 protein was strongly expressed in NFI-C deficient mouse compared with wild type. These findings suggest that NFI-C deficiency affects odontoblast differentiation and result in the formation of abnormal roots. Therefore, balancing between NFI-C and TGF-${\beta}$ signaling including Smad4 is important for the regulation of normal odontoblast differentiation and dentin formation.
Background: Regardless of countries, the myth that rain makes the body ache has been worded in various forms, and a number of studies have been reported to investigate this. However, these studies, which depended on the patient's experience or memory, had obvious limitations. Google Trends is a big data analysis service based on search terms and viewing videos provided by Google LLC, and attempts to use it in various fields are continuing. In this study, we endeavored to introduce the 'value as a research tool' of the Google Trends, that has emerged along with technological advancements, through research on 'whether toothaches really occur frequently on rainy days'. Methods: Keywords were selected as objectively as possible by applying web crawling and text mining techniques, and the keyword "bi" meaning rain in Korean was added to verify the reliability of Google Trends data. The correlation was statistically analyzed using precipitation and temperature data provided by the Korea Meteorological Agency and daily search volume data provided by Google Trends. Results: Keywords "chi-gwa", "chi-tong", and "chung-chi" were selected, which in Korean mean 'dental clinic', 'toothache', and 'tooth decay' respectively. A significant correlation was found between the amount of precipitation and the search volume of tooth decay. No correlation was found between precipitation and other keywords or other combinations. It was natural that a very significant correlation was found between the amount of precipitation, temperature, and the search volume of "bi". Conclusion: Rain seems to actually be a cause of toothache, and if objective keyword selection is premised, Google Trends is considered to be very useful as a research tool in the future.

Smartphone usage has become so common that it has reached 2 billion people in the last year. As a result of this, hospitals have started making use of smartphones at various medical sites and research services for patients. This study aimed to establish support for developing a long distance program for patients with implants who have difficulty visiting clinics or with busy modern lives, by using smartphones for oral hygiene management instruction. The data were collected for 12 weeks, from July 24 to October 21, 2015, for patients who agreed to participate in the study. Although the subjects found the process of transferring photos via smartphone to be cumbersome (75%), the satisfaction level of the oral hygiene management program was excellent for all participating patients, and they all wanted to continue with further management using this process. The results from the phone satisfaction survey showed that oral hygiene self-management after oral hygiene control training by smartphones was mostly equal to previous habits (87.5%) or had partially increased but had not decreased. The need for data on more varied age groups and the issues of protecting the security of personal information on smartphones require further study. However, our study confirmed the efficacy of using electronic media (smartphones) for oral hygiene management in patients with a dental implant due to their improvement of oral hygiene performance as evidenced by less bleeding from probing on post-program visit.
Objectives : This research aims to analyze the relationship between the state of mental illness and oral health management of mental patients in mental health care institutions. Methods : The data were randomly selected from 474 patients in mental health care institutions. and analyzed by SPSS WIN 12.0 program. Results : Schizophrenia accounted for 79.5%(337 patients) ; alcohol dependency, 5.3%(25 patients) ; mental retardation, 2.7%(13 patients) ; mental development disorder, 3.0%(14 patients) ; mental delusion and dementia, 7.6%(36 patients). Those who were in 40s had the highest dental caries of 3.95 and the highest remaining teeth of 26.76 were shown in the 20s. The correlation between remaining teeth and mental retardation was the highest, measuring 22.38(p<.05). Those who were in 70s had the serious periodontal condition that accounted for 41.3%(12 patients)(p<.05). The correlation coefficient for all factors-dental caries, remaining teeth, need for scaling, and periodontal condition-between mental illness condition and oral health were all positive(p <.05). The regression analysis resulted in the formula Y(mental health condition)=2.999+0.166(dental aries)-0.028(remaining teeth). Conclusions : Those who had mental illness had very poor and serious dental caries and periodontal diseases, so it is necessary to manage the dental health care for the mentally ill patients.
The purpose of this study was to examine the health segment of the 7th national physical education curriculum in an effort to grasp the state of oral health education in the school curriculum. And it's also meant to investigate the relationship between oral health education and the oral health awareness of some high schoolers to check into any possible problems with oral health education as part of health education. The subjects in this study were 240 students from two different girls' high schools in Seoul, on whom a survey was conducted to find out their oral health knowledge, behavior and awareness. And the health category of the current P.E. curriculum announced by the Ministry of Education was analyzed. The findings of the study were as follows: Oral health education provided by the high schools as part of health education in P.E. class wasn't linked to P.E. theories and practice. The weight of oral health education was extremely small in the health segment, and there was no sequence, continuity and integration among the content systems of oral health education for different grades. When some high schoolers were investigated, they weren't properly oral health conscious, though it was very important for students to receive oral health education to prevent and manage dental diseases. And they didn't consequently take care of their own oral health. Future research efforts should be channeled from diverse angles into developing oral health education curriculums to bolster school oral health education to improve national oral health.
