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. Interventions of dental material were the most in pre experimental design (19.2%) and Interventions of activation of oral health program were the most in quasi experimental design (37.5%).

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.

Objectives: Prunus mume has been used for the folk medicine from old times. The purpose of the study was to investigate the antimicrobial activity of prunus mume extract to various oral microbes. Methods: This study was carried out to examine the antimicrobial effect of Prunus mume extract against oral microbes. Data were collected using a Dentocult SM Strip mutans and Dentocult LB Strip mutans from April 5 to May 4, 2013. A total of 36 experimental and 32 control group were selected for this study. Results: The MIC of Prunus mume extract was tested for 0.39% in S. mutans, S. salivarius and S. auerus, 0.78% in S. mitis, S. equi and E. coli. In vivo, experimental group showed significantly the lower Streptococcus mutans levels by the use of the gum contained Prunus mume extract from 15 days compared with control group(p=0.012). The reduction was more significant in Lactobacilli level of the experimental group than the control group(p=0.022).

Objectives. This study investigated on the severity of dry mouth in the elderly and the association between dry mouth(low, moderate and high) with pre and post wearing denture satisfaction. Methods. Data were obtained from a cross-sectional survey of 102 elderly people (mean age=69.3). Participants in the study were recruited when they attended the public health center in Seoul and Gyeonggi-do. Data were collected by means of a personal interview from March 14 through to May 23, 2009. Pre and post wearing denture satisfaction was measured by the 24-items and dry mouth was measured by the 4-items. The data was analysed with t-test, One-way ANOVA, and Logistic regression using the SPSS program. Results. Regarding perception of dry mouth, the subjects achieved a mean of 6.13 out of a maximum 12 points. Scores were categorised as high (8∼12), medium (5∼7) or low (1∼4) and the propotion were 24.5% (9.56), 42.2% (5.81) and 33.3% (4.00) respectively. Those who were older and had fewer natural teeth felt that their perception of dry mouth was more severe. A logistic regression analysis showed that the subjects` perception of dry mouth had a significant impact on their gender (OR=2.73), comfort (OR=0.21), aesthetic appreciation (OR=7.56) satisfaction. Conclusions. Based on the findings, the perception of dry mouth has a significant and negative impact on denture satisfaction. These results suggest that oral health promotion should be considered various factors related dry mouth in the elderly with removable denture.
