Objectives: The purpose of study is to investigate trends in dental hygiene research published in the Journal of Korean Society Dental Hygiene. Methods:Total of 992 researches were published between 2001 to 2015 were reviewed using analysis criteria. Results: 23.7% of the researches were supported financially. The most frequent research topics were oral health (40.9%). 3 to 5 researchers per research (38.5%) was most common and 84.1% of principal researchers were professors. 29 researchers were approved by IRB (2011 to 2015). As for the type of research, 87.1% of quantitative studies adapted survey and 9.5% adapted experiment. Convenient sampling was used in 85.6% of the researches. 32.7% of studies searched information in school.

Objectives: This study aimed to analyze the dental hygiene students and professors’ knowledge and attitudes related to medical ethics and their level of perception of professional ethics education. Methods: This was a cross-sectional survey study of 330 students and professors in the field of dental hygiene using a structured questionnaire. The sub-factors of knowledge and attitudes related to medical ethics were classified into patient relations, medical and social relations, and individual specialized fields, and analyzed for comparison. Results: In the university curriculum, the professional ethics completion rate was 34.8% for students and 22.1% for professors, but 98.5% of respondents said that professional ethics is important. Their knowledge and attitudes related to medical ethics were average, ranging from 5 points to 3.37 points, followed by “relationships with patients (3.75 points)”, “medical and social relations (3.19 points)”, and “individual specialties (3.16 points).” Conclusions: Students and professors who major in dental hygiene recognize the importance of professional ethics, but the level of knowledge and attitude related to medical ethics has been found to be moderate. Therefore, it is suggested that medical ethics, including professional ethics, should be treated as an essential subject in the university curriculum.

Objectives: We evaluated the level of oral health status and oral health behavior in the elderly prior to their participation in a visiting oral health care intervention program as part of a community healthcare project in Cheonan city, South Korea. Methods: The oral hygiene conditions, oral health behaviors, and oral senility of 64 elderly people subject to community care were measured during the period January 1 to February 15, 2020 using dental health surveys and questionnaire-based interviews conducted in line with World Health Organization standard criteria. Results: The systematic disease retention rate of the elderly in this study was 90.6%, followed by hypertention (70.7%), and diabetes (51.7%). Scores were 1.69 out of 5 for subjective health evaluation, 1.8 out of 5 for subjective awareness of oral health, and the number of natural teeth was 14.9 per person (average mean for elderly people 18.38-19.34). During the day, 94.9% practiced brushing, after dinner 58.9%, and before bedtime 26.8%, which shows a diminished rate of practice. The percentage of participants dissatisfied with dental treatment was high at 67.2%, and the six measures of oral sensitivity, masticatory discomfort, pronunciation discomfort, and tongue pressure, presented less than average scores. Conclusions: The level of oral health and oral health behavior of the elderly prior to the visiting oral health care community intervention program, was very poor. Therefore, the results of this study suggest that there is a need to develop a more systematic and thorough strategy to activate visiting community oral health care intervention programs.

The purpose of this study was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and crossover clinical studies in 33 healthy adults aged from 20 to 22 years who provided a consent for their participation. Oral examination was performed through clinical periods and on day of baseline, 6, 13, 19, 25 days plaque index and gingival index were scored by Turesky` modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 12 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). This result Indicate that the use of dentifrice containing extract of garlic has a positve effect in preventing plaque and gingivitis and treating periodontal diseases.

The purpose of this study was to investigate research ethics awareness for health and medical science researchers. The variables for the study included intrinsic motivation, knowledge sharing for research ethics awareness. The data were collected from 254 employees of the research ethics awareness who gave their informed consent and completed a self-reported questionnaire in May, 2017. A path analysis model was established and used to assess parameters such as research ethics concern, intrinsic motivation, knowledge sharing for research ethics awareness. The fitness of the hypothetical model was adequate(X2=49.585, GFI=0.954, NFI=0.895, CFI=0.915, IFI=0.916, RMR=0.021). Research ethics interest was found to have a positive influence on intrinsic motivation, knowledge sharing, and research ethics consciousness. Intrinsic motivation as a parameter was positively (+) influence on knowledge sharing. SMC (Squared Multiple Correlations) is a multiple correlation coefficient which is explained by exogenous variables, and explanatory power of intrinsic motivation, knowledge sharing, and research ethics are 15.2%, 24.0% and 18.0%, respectively. Research ethics interest in the research ethics of health and medical science researchers was significant as direct and indirect effects. In order for the correct ethical consciousness to be established, it is necessary to raise the interest in research ethics, and to establish an intervention strategy to strengthen the intrinsic motivation of the research as well as sharing knowledge among researchers.

Objectives: This study was to determine the level of occupational exposure and quality of life and to investigate the effect of variables related occupational exposure on quality of life in dental hygienists. Methods: A survey questionnaire was mailed to dental hygienists from April 4 to May 15, 2010. The subjects were 256(56.9%), who were worked in dental hospital and clinic with mean age of 29.59±7.30. Quality of life was measured using the WHOQOL-BREF. It consists of 26 items, each with 5-point likert scale. Self control of occupational exposure was measured using the 3-items. The data were analyzed with chi-square, t-test, one-way ANOVA, pearson correlation coefficients and multiple regression using the SPSS WIN 17.0 program. Results: Regarding quality of life, the subjects was a mean of 90.73 out of a maximum 130 points. The level of self control occupational exposure a mean of 3.20 out of a maximum 5 points. Self control of occupational exposure, frequency of panorama radiography, work experience of radiography had a significant impact on quality of life in dental hygienists. Conclusions: Based on the findings, occupational exposure is negatively associated with quality of life in dental hygienists. These results suggest that health promotion program should be considered various factors related occupational exposure in dental hygienists. (J Korean Soc Dent Hygiene 2010;10(4):717-725)
