The purpose of this study was to examine relation of oral health awareness, knowledge and behavior in department dental hygiene, health-related majors and health-unrelated majors in attempt to provide basic data of oral health promotion and oral health education. This study were 591 female H university students in Gwangju. The interests of oral health, the recognition of importance for oral health, and recognition of one's own oral health status were highest in dental hygiene students, followed by health-unrelated majors and health-related majors. The level of oral health knowledge by the major was highest in dental hygiene students(9.73), followed by health-related majors(9.14) and health-unrelated majors(9.05). In the oral health behavior by major, students who brushed more than three times a day, used the oral care products and received regular dental examinations within 1 year were the highest in the dental hygiene major, followed by health-related majors and health-unrelated majors. The experience of scaling within 1 year was the highest in the dental hygiene major, followed by health-related majors and health-unrelated majors. The higher the oral health knowledge, increased awareness of oral health concern and the importance of oral health. Also, the higher the degree of interest in oral health, the greater the recognition that oral health is important and the more the oral health condition is perceived as healthy, It was found that the number of brushing increased. In this results, the higher the oral health knowledge, the higher the oral health awareness and the oral health behavior. It is necessary to find ways to develop or utilize various oral health education for university students.
The present study attempts to investigate the knowledge, belief, attitude and behavior of healthcare major students and non-healthcare counterparts concerning their oral hygiene. The purpose is to provide basic data for positive oral health activities to the students with non-healthcare major, who tend to have insufficient information on oral hygiene. A survey was conducted to 400 students in K college in Incheon from May 1-30, 2003. A total of 384 surveys were analyzed using the SPSS program Version 10.0. The result is as follows: 1. There was a statistically significant difference in the knowledge on oral hygiene between the healthcare(M=3.08) and non-healthcare(M=2.78) students(pE0.05). 2. As for the beliefs and attitudes toward oral health behaviors, 56.9% of the healthcare students and 60.6% of non-health care counterparts responded "moderate" to the question asking if they liked tooth-brushing. The reason they liked tooth-brushing were cleanliness(60.3% of healthcare and 71.9% of non-healthcare students). They didn't like brushing their teeth because they felt it was a nuisance(60.6% of healthcare and 54.5% of non-healthcare students). 90.6% of healthcare students and 90.1% of their non-healthcare counterparts said they wanted to keep their oral health intact. Most of the subjects seemed to acquire information on oral hygiene through mass media(62.2% of healthcare and 55.3% of non-healthcare students). The persons who give them oral health information are their friends or neighbors(26.8% of healthcare and 22.8% of non-healthcare students), and dental hygienists were the last in the list of the sources of information(3.4% of healthcare and 2.5% of non-healthcare students). 3. Their oral health behaviors were also considered, 64.4% of the healthcare students and 53.7% of the non-healthcare counterparts brush their teeth once or twice a day, 51.4% of the former brush their teeth for 2 minutes and 44.8% of the latter for 3 minutes. Some of them use oral health measures other than tooth-brushing(13.3% of healthcare and 14.3% of non-healthcare students). Not many of them used oral health products(6.6% of healthcare and 5.9% of non-healthcare), and the difference was statistically significant(pE0.05). The largest number of healthcare students brush their teeth right before going to bed(29.9%), while their counterparts do it after breakfast(25.8%)
Rice is the most important crop in Korea and its annual production of 5.2 million ton is followed by over 0.5 million ton of bran as by-products of milling process.

Objectives : The purpose of the study is to investigate the deciding factors of regular scaling checkup in metropolitan adults. Methods : The subjects were 395 adults of 20s to 50s in Seoul and Gyeonggi province from September 25 to October 4, 2012. Data were self-reported questionnaires. Results : Female tried to receive more regular scaling checkup than male. Dental practitioners were acquainted with the dental knowledge and had more scaling checkup. Those who received dental scaling checkup tended to use dental hygiene products and visit the dentists regularly. Those who receiving good dental health services tended to visit the dental clinics more frequently. Higher knowledge and lower fear of dental treatment lead to frequent regular checkup. There were significant positive correlations between satisfaction, kindness, knowledge of scaling and regular scaling checkup. Fear to dental treatment showed the negative correlation. Conclusions : In order to increase intention degree of regular scaling checkup, it is necessary to develop programs for proper oral health behavior and to improve patient care services by dental hygienist.

Pectin lyase-modified red ginseng extract (GS-E3D) is a newly developed ginsenoside Rd-enriched ginseng extract. This study was designed to investigate the skin safety of GS-E3D. Single oral toxicity, single dermal toxicity, bovine corneal opacity and permeability (BCOP) assay, skin irritation test with $SkinEthic^{TM}$ human epidermis model, skin sensitization local lymph node assay, and human patch test, were examined. The oral and dermal $LD_{50}$ value of GS-E3D was over 2,000 mg/kg in rats. GS-E3D was identified as a non-irritant to skin in BCOP assay, human epidermis models, and patch test from the 32 human subjects. The skin sensitization potential of GS-E3D was less than 25% in local lymph node assay. These results indicate that GS-E3D can be used as a safe ingredient without adverse effects in various skin care products.
The purpose of this study was to examine the relationship between the oral health behavior and self-efficacy of adolescents. The subjects in this study were 300 selected students in a girls' high school located in the city of Iksan. A survey was conducted from November 2 to 5, 2014, with questionnaires that covered oral health behavior and self-efficacy, and the answer sheets from 298 respondents were analyzed by a statistical package IBM SPSS Statistics ver. 21.0. The group that got regular dental checkups (3.26) excelled the other group that didn't in self-efficacy (p<0.05), and the group who made use of oral care products and who brushed their teeth four times or more had a better self-efficacy than the other group that didn't. The students who considered themselves to be in better oral health scored higher in self-efficacy, and the groups who had no difficulties in pronunciation (3.66) and mastication (3.32) scored higher (p<0.01, <0.001). Masticatory dysfunction (r=-0.184) and pronunciation disorder (r=-0.200) were negatively correlated with self-efficacy, but oral health status (r=0.243) had a positive correlation with it. Self-efficacy was better when oral health status was better (p<0.001) and when there was no pronunciation disorder (p<0.01). The above-mentioned findings suggested that there was a close relationship between oral health behavior and self-efficacy. Therefore the kind of program that aims at changing youth oral health awareness and oral health behavior should be prepared to improve the self-efficacy of adolescents.
Flavonoids from Scutellariae Radix possessed a dual function both as an anti-inflammatory agent and an enhancer of cellular activity in gingival fibroblast. The purpose of this study was to evaluate on the toxicity of ethanolic extract from the root of Scutellariae Radix Georgi and its flavonoids, Wogonin, Baicalein, and Baicalin were isolated and purified by the following method. The crude drug was extracted with ethyl acetate and the residue was dissolved in ethyl alcohol. The ethyl alcohol soluble fraction was separated, concentrated, and then chromatographed on a silica gel column. The acute oral LD 50 in rats was determined for EtOH ex. of Scutellariae Radix and three compounds were evaluated with a single oral gavage at three graded dosage levels. The acute intravenous LD 50 was determined with a single intravenous injection via the jugular vein at three graded dosage levels. Groups of 5 male and 5 female rats, 6 week of age at the start of the study, were fed diets containing 3 graded dosage levels for 14 days. Groups of 5 male and 5 female hamster received O.5ml of the test article at once in a day for 5 days to the buccal cheek pouch for two minutes each. The acute oral LD50 for EtOH ex. of Scutellariae Radix is 1430mg/kg, and for Wogonin 1320mg/kg, for Baicalein 1250mg/kg, for Baicalin 1330mg/kg. The acute intravenous toxicity of EtOH ex. of Scutellariae Radix and its extracts was found to be 27mg/kg body weight No toxic effects were observed in rats fed up to 200mg/kg of EtOH ex. of Scutellariae Radix, Wogonin, Baicalein and Baicalin in the diet for 14 days. The acute Mucouse Membrane LD 50 in hamsters was found to be greater than 100mg/kg. These results suggested that EtOH ex. of Scutellariae Radix and its flavonoids are safe for oral care products using limited amount of extract.
Objectives : This study aimed to investigate the history, current status, and regulation of complementary medicine in Australia. Methods : To investigate complementary medicine in Australia, we searched domestic and overseas academic databases, and websites of public and private organizations related to the Australian health care. Results : Complementary medicine consists of numerous services, among which massage and chiropractic care are significantly utilized by Australians. Since 2010, Australian healthcare practitioners, in the field of complementary medicine, have been supervised by the Australian Health Practitioner Regulation Agency (AHPRA). Those who AHPRA is responsible for managing acupuncturists, chiropractors, and osteopaths. Other professions are regulated by their own respective associations. Not only aforementioned services offered by specialists, but also consumption of oral supplements accounts for considerable portion of complementary medicine in Australia. Complementary medicine products, vitamins, and minerals are managed by the Therapeutic Goods Administration (TGA). In terms of insurance policy, the reimbursement of complementary medicine expenses in Australia is covered by the public healthcare insurance system, Medicare. Medicare covers acupuncture, chiropractic, and osteopathy services. Other complementary therapies are continuously reviewed to update their coverage under this scheme. Conclusion : In Australia, practitioner qualifications, education standards, and scope of procedures related to complementary medicine are systematically managed through legal regulations of the federal and state governments.
It is well known that many antimicrobial proteins in saliva interact with each other. The purpose of the present study was to investigate the interactions of lysozyme with peroxidase in the aspects of enzymatic activity in vitro. The interactions of lysozyme with peroxidase were examined by incubating hen egg-white lysozyme(HEWL) with bovine lactoperoxidase(bLP). The influence of peroxidase system on lysozyme was examined by subsequent addition of potassium thiocyanate and hydrogen peroxide. Lysozyme activity was determined by turbidity measurement of a Micrococcus lysodeikticus substrate suspension. Peroxidase activity was determined with an NbsSCN assay. The Wilcoxon signed rank test was used to analyze the changes of enzymatic activities compared with their controls. bLP at physiological concentrations enhanced the enzymatic activity of HEWL(P < 0.05) and its effect was dependent on the concentration of peroxidase. However, HEWL did not affect the enzymatic activity of bLP. Thiocyanate did not affect the enzymatic activity of HEWL, either. The addition of potassium thiocyanate and hydrogen peroxide did not lead to additional enhancement of the enzymatic activity of HEWL. The changes of hydrogen peroxide concentration in the peroxidase system did not affect the enzymatic activity of HEWL. Collectively, despite an in vitro nature of our study, the results of the present study provide valuable information on the interactions of lysozyme and peroxidase in the aspects of enzymatic activity in oral health care products and possibly in the oral cavity.
