Objectives: The study aimed to investigate the perception and usage of oral hygiene products among patients who visited dental hospitals or clinics. Methods: A questionnaire was provided to a total of 187 patients who visited dental hospitals or clinics in Gyeongnam area. The answers were then statistically analyzed. Results: Interest in oral hygiene (r=0.194, p<0.01) and the subjective perception of oral health (r=0.232, p<0.01) had a significant positive correlation with oral hygiene device awareness. Moreover, this study showed that females (β=-0.185, p<0.05) and those with greater interest in oral health (β=0.156, p<0.05) were more familiar with and used toothbrushes regularly. Finally, this study showed that females (β=-0.459, p<0.001) and those who did not suffer from halitosis (β=-0.215, p<0.01) were more familiar with and used oral hygiene devices regularly. Conclusions: To ensure the proper recognition and use of oral hygiene devices, professional oral health education is necessary. Furthermore, various forms of media should be used to disseminate information on oral hygiene devices.

Background: Tobacco products continue to be used in large quantities in India despite the mandatory inclusion of pictorial health warnings (PHWs) on all tobacco packaging. The circumstances as to how people could continue the use of tobacco to the point of developing head and neck cancer despite enhanced awareness about the ill effects of tobacco is the main focus of this study. Materials and Methods: This study concerned patients with least 5-years history of tobacco use, having been diagnosed with histopathologically proven malignancies of the hypopharynx, larynx, oropharynx and oral cavity presenting at the Government Medical College-Haldwani, Nainital, India. A total of 183 patients were eligible for inclusion during July 1 2013 - June 30 2014. Of these, 59 patients used smoked tobacco exclusively, 22 patients used smokeless tobacco exclusively, and 102 patients used both forms of tobacco. Among users of smoked forms, 75.2% (n=121) were beedi users, and 24.8% (n=40) were cigarette users. Patients were asked direct questions as to whether they had noticed the presence of PHWs upon tobacco products. The reasons as to why PHWs were not effective in stopping the patients from tobacco use were investigated. Results: Of the 183 patients, 146 reported being aware about the presence of PHWs, and when they were asked reasons as to why they continued tobacco despite being aware of ill-effects, the commonest reason chosen (by 53.4%) was that patients had not regarded themselves as using tobacco heavy enough to cause cancer. Among the 36 patients who reported as being oblivious to the presence of PHWs on tobacco products, 63.9% reported that the products they used never displayed any PHWs, and 36.1% reported never having paid attention to the packaging. The awareness about PHWs was higher among cigarette smokers in comparison to beedi smokers (100% vs 76.1%, p=0.0002). Conclusions: Locally produced and marketed tobacco products such as beedis and oral tobacco often fail to display PHWs. The presence of PHWs without doubt enhances awareness about the carcinogenic risks of tobacco. However, enhanced awareness alone may not be enough, and as elucidated by this study, some persons continue to use tobacco to the point of developing malignancies. The need of the hour is the implementation of legal and economic sanctions discouraging the use of tobacco products.

Purpose: This study was aimed to examine the financial effect of 2-tiered copayment system on annual expenditure of pharmacy benefit in the National Health Insurance (NHI) of Korea, focusing on oral antidiabetic medications. Methods: 284 oral antidiabetic products with 14 different active single ingredients listed in the National Formulary of NHI (August 2009) were assigned to tier 1 or tier 2 according to the selected criteria. 10 different combinations of coinsurance rates were selected to estimate the changes in drug expenditure cost of NHI. Results: The annual drug cost was estimated based on the drug price per unit listed in the National Formulary and the used amount of products in 2009 from the IMS Health data of Korea. In the combinations of coinsurance rate of 20% for tier 1 and 40% for tier 2, the total annual drug cost was estimated to be reduced by 1.3% in the case of no change of generic and original drug consumptions, and to be reduced by 4.3% in the case of 10% increased generic drug consumptions. Conclusion: The tiered copayment system with optimal coinsurance rates appears to be a potential strategy to reduce the financial burden of NHI in Korea by promoting the use of generic products.

There is increasing evidence that the environmental hormones may adversely affect the human body. The human reproductive system misrecognizes some of these endocrine disruptors with consequences to reproductive cell differentiation. Therefore, studies on the safety of these substances have been widely carried out to develop the science to create effective legislation to limit or prevent their use or require the development of inert, alternative substances. A few studies have reported that the oral cavity is the pathway for absorption of these substances released from plastic products or environmental hormone substances. This review suggests that the oral environment is vulnerable to exposure to environmental hormones and introduces supporting literature.

The purpose of this study was to investigate the relationship between hormone replacement therapy (HRT) and periodontal disease in postmenopausal women using data from the 4th and 5th Korea National Health and Nutrition Examination Survey. A total of 5,482 postmenopausal women aged 45~75 years were included as study subjects in the final analysis. The HRT group comprised 1,035 postmenopausal women who had received HRT for at least one month, and the non-HRT group comprised 4,447 postmenopausal women who did not receive HRT. The chi-square test was used to confirm the bivariate relationship between the variables. Multinomial logistic regression analysis was used to adjust for covariance (age, education, family income, body mass index, age of menopause, alcohol, smoking, dental visit <1 per year, use of oral care products, and frequency of tooth brushing per day). After adjusting for all covariates, HRT was found to be associated with periodontal disease. In particular, the relationship between HRT and periodontal disease was more evident in older women and women younger than 45 years of menopausal age. The relationship between HRT and periodontal disease was stronger in women who brushed their teeth less than 3 times per day, women without regular oral examination, and women who did not use oral hygiene products. The results of this study confirmed the importance of actively considering hormone therapy when determining policy recommendations for postmenopausal women. Especially, health programs such as HRT, regular dental examination, and oral care are needed for older women who have undergone premature menopause.

Licorice, which has an extensive history of use as an herbal medicine, has been suggested to have oral health benefits. However, to date, no systematic study has been conducted on the preparation method of licorice extracts for oral health. In this study, licorice extracts prepared using water and ethanol were investigated for its ability to inhibit the biofilm formation of Streptococcus mutans. The licorice extract prepared with around 60% ethanol effectively inhibited the biofilm formation of S. mutans. Licorice extracted with 50% ethanol almost completely inhibited the biofilm formation at 1.5 g/L of licorice extract. This inhibitory activity was confirmed in a microplate assay and a flow cell system. Glycyrrhetic acid was extracted from licorice effectively with 60% ethanol concentration. The strong inhibitory activity of glycyrrhetic acid and the synergistic inhibition with glycyrrhizin on biofilm formation were suggested as major reasons for a concentration-specific extraction. These results suggest that licorice extract prepared using around 60% ethanol effectively inhibits the biofilm formation of S. mutans.
