Education should consider the social consensus that changes according to the times and the social environment, and it is also necessary to consider the technically useful subjects. We collected and reported the 4-year course curriculum of dental hygiene when Korean dental hygiene education has continued over 50 years. Each 4-year course curriculum was collected by searching each university website, or requested by email. The curriculum of 23 among 27 schools was collected. According to the classification of dental hygiene in the dental hygienist national examination classification or the Korean society of dental hygiene science, the subjects of the course were divided into clinical dental hygiene, clinical dental treatment support, basic dental hygiene, social and educational dental hygiene, and collected 23 curriculum courses. The average major curriculum was 104.9 credits and the average number of subjects in major courses was 34.3. The average subjects' number of clinical dental hygienic courses was 33.9 (37.5% of the total major credits), clinical dental treatment support was 30.6 (30.2% of the total major credits), basic dental hygiene was 21.8 (20.8% of the total major credits), and social and educational dental hygiene courses was 13.6 (13.0% of total major credits). Integrated subjects' name in clinical dental hygiene was used in all schools of the survey, such as clinical dental hygiene education (and practice), comprehensive dental hygiene education, and integrated dental hygiene. There were 13 schools (56.5%) that use the integrated name in clinical dental treatment support, such as clinical dentistry. There were 14 schools (60.9%) to open dental clinic management, and 22 schools (95.7%) to open national health insurance claims. The basic dental hygiene curriculum maintained the title of each subject and social and educational dental hygiene education was established in most schools, such as community dental health, oral health statistics, and oral health education. Other subjects were English conversation in dental clinic (8 schools) education, clinical dental treatment support, basic science in dental hygiene, social and educational dental hygiene. We knew the clinical dental hygiene and clinical dental treatment support were changing into the integrated subjects, and most schools run dental hygiene research.

Background: Some studies confirm the reduction of the number of Streptococcus mutans in saliva and dental plaque by Lactobacillus, however, these effects are not always confirmed in in vitro and clinical studies, and only the risk of dental caries has been reported. Our in vitro study aimed to reveal microbial and biochemical changes in the single cultures of S. mutans, Lactobacillus casei and Aggregatibactor actinomycetemcomitans and co-cultures of S. mutans and L. casei or A. actinomycetemcomitans according to sucrose concentration. We also aimed to confirm the anti-oral bacterial and anti-biofilm activities of L. casei and A. actinomycetemcomitans against S. mutans according to sucrose concentration. Methods: S. mutans (KCCM 40105), L. casei (KCCM 12452), and A. actinomycetemcomitans (KCTC 2581) diluted to 5×10⁶ CFU/ml were single cultured, and L. casei or A. actinomycetemcomitans applied at concentrations of 10%, 20%, 30% and 40% to S. mutans were co-cultured with selective medium containing 0%, 1% and 5% sucrose at 36.5℃ for 24 hours. Measurements of bacterial growth value and acid production, disk diffusion and biofilm formation assays were performed. Results: In the medium containing sucrose, the bacterial growth and biofilm formation by S. mutans, L. casei, and A. actinomycetemcomitans were increased. In contrast, 30% and 40% of L. casei in the medium containing 0% sucrose showed both anti-oral bacterial and anti-biofilm activities. This implies that L. casei can be used as probiotic therapy to reduce S. mutans in a 0% sucrose environment. Conclusion: The concentration of sucrose in the oral environment is important for the control of pathogenic bacteria that cause dental caries and periodontitis. To apply probiotic therapy using L. casei for S. mutans reduction, the concentration of sucrose must be considered.

Objectives: It is crucial to detect and prevent oral problems early. Older adults, in particular, should go for regular dental checkups to maintain a healthy oral environment. This study identified the factors affecting regular dental examinations and unmet dental needs in older adults. Methods: This study analyzed 3,362 older adults aged 65 or over using the data from the 7th Korean National Health and Nutrition Examination Survey (KNHANES). Frequency analysis was performed on general characteristics. In addition, chi-square tests were done to determine differences in regular dental checkups and unmet dental needs according to general characteristics. Logistic regression analysis was performed on factors influencing regular dental checkups and unmet dental needs. Results: Factors influencing regular dental checkups were statistically significant according to residential areas, level of education, household income, and levels of physical activity (p<0.05). Factors influencing unmet dental needs were statistically significant according to residential areas, level of education, private medical insurance, and levels of dental pain (p<0.05). Conclusions: National level policy strategies should be implemented to improve the oral health of older adults. These strategies should encourage regular dental checkups to effectively lower the rate of unmet dental needs.

Objectives: This study was conducted at a request for cooperation through an analysis of the effect of toothbrushing facilities at a public health center in Seongdong-gu. Also, with the aim of furnishing basic data to the proposal of a program for improving the ability of school aged children in managing oral cavities and developing a correct toothbrushing habit, the study conducted an investigation of how toothbrushing facilities affect change in the oral environment management ability and behavior of oral health care. Methods: From among elementary schools located in Seongdong-gu, Seoul the study selected A Elementary School where toothbrushing facilities were established and have been operated since 2008, B Elementary School in an adjacent region within the jurisdiction of Seongdong-gu where the demographic environment was similar among schools where toothbrushing facilities were newly established in 2012, and C Elementary School without toothbrushing facilities. Then the study was aimed at first grade students of the schools and an investigation was carried out from April to December 2012. Through a dental checkup, the study evaluated the teeth and periodontal health conditions, and a test of the oral environment management ability was undertaken three times. Regarding change of oral health care behavior, the study carried out a self-recording survey. Results: 1. Concerning decayed and filled tooth(dft) and decayed and filled surface (dfs), A Elementary School where toothbrushing facilities have been established and operated from the past showed a relatively lower decayed, missing, and filled teeth index than B Elementary School where toothbrushing facilities were established in 2012 or C Elementary School without toothbrushing facilities; however, there was no significant difference (p>0.05). For CPI, there was no significant difference by school; however, in looking into the difference between boy students and girl students, Code (0) was discovered higher in boy students whereas Code (1) was shown higher in girl students. 2. In the PHP index test in accordance with the existence of toothbrushing facilities before the installation of toothbrushing facilities, for A Elementary School where toothbrushing facilities have been established and operated from the past, the school recorded 4.28 points whereas B Elementary School where the facilities were established in 2012 recorded 3.51 points. Meanwhile C Elementary School without the facilities posted 4.30 points. Therefore there was a statistically significant difference according to the existence of toothbrushing facilities (p<0.05). 3. In a comparison of teeth health care behavior according to the existence of toothbrushing facilities, the number of answers that the respondent did not brush their teeth after lunch over the past one week was higher in B Elementary School and C Elementary School where there were no toothbrushing facilities. Regarding the average number of brushing after lunch for one week, it was discovered higher in A Elementary School (p<0.01). 4. In change of teeth health care behavior before and after the establishment of toothbrushing facilities, the case of answering that the respondents did not brush their teeth after lunch for one week increased more after establishment than before establishment. Also the average number of teeth brushings after lunch for one week decreased further after the establishment of toothbrushing facilities; however, it did not show a significant difference (p>0.05). One of the reasons that they do not brush their teeth, "the lack of a place", decreased significantly after establishment than before establishment (p<0.05), whereas the answer, "because their friends do not brush their tooth" increased greatly after establishment than before establishment; however, there was no significant difference (p>0.05). 5. In the comparison of the degree of knowledge about dental health according to the existence of toothbrushing facilities, the degree of knowledge about dental health was shown significantly higher in A Elementary School with toothbrushing facilities than in B Elementary School and C Elementary School where there were no toothbrushing facilities (p<0.01). Conclusions: Given the above results, it is difficult to attract change in behavior only with an environmental improvement; therefore, it is deemed necessary to develop an educational program that will help children to make a habit of oral health care not only through a school but also through a related policy and financial support of government organizations as well as the construction of the basis of a systematic and consistent cooperative system with relevant organizations.
