The purpose of this study was to evaluate the relationship between early menopause and periodontal disease in postmenopausal women using data from the 6th Korean National Health and Nutrition Examination Survey (2013~2015). A study was conducted with 2,048 postmenopausal women aged 45 to 74 years. Participants were divided into the early menopause group (menopause occurring at age 45 years or before) and normal menopause group (menopause occurring after age 45 years). A community periodontal index greater than or equal to code 3 was used to define periodontal treatment needs. A chi-square test was used to confirm the bivariate relationship between the variables. Multinomial logistic regression analysis was used to adjust for covariates (age, education, family income, body mass index, alcohol drinking, smoking, visiting dentist in the last year, use of oral care products, frequency of tooth brushing per day). The risk of periodontal disease was higher in the early menopause group after adjusting for potential confounders (odds ratio, 1.59). In particular, the relationship between early menopause and periodontal disease was more evident in women with low education and those who did not use oral care products. The findings of this study suggest that early menopause is a significant factor of periodontal disease in Korean women.

Objectives: The purpose of this study was to investigate the oral health education and oral health care in the implant wearers. Methods: A self-administered questionnaire was conducted by 253 patients in 14 different dental hospitals and clinics in Seoul and Gyeonggi-do from July 1 to September 30, 2012. The instrument was adapted from Kang and Lee, Yu and Shim, and Ko and Jang on the basis of the previous study. The questionnaire consisted of 12 questions including general characteristics of the subjects(4 questions), oral health education(3 questions), behavior and attitude of tooth brushing(3 questions), and use of auxiliary supplies(2 questions). Results: 1. 38.3% of the patients received the dental care education for the first time. The most common education method was demonstration by dental hygienists(28.9%). 26.2% of the patients wanted to know the right toothbrushing method. 2. The best toothbrushing methods were rolling method(28.9%) and Leonard's method(28.9%). 19.4% of the patients changed the toothbrushing method after education. 22.5 percent brushed their natural teeth and implant teeth by a different maneuver. 3. The interdental brush was the most commonly used product(35.8%) and most of the patients the interdental brush once a day(36.6%). 4. There was a significant difference between the frequency of toothbrushing and method(p<0.05). 5. There was a significant difference between the separate brushing of implant and natural teeth by the frequency of toothbrushing and method of education(p<0.05). 6. Use of interdental brush had an influenced on education method(p<0.05). Conclusions: Regular dental checkup and use of interdental brush can improve the oral care for the implant wearers. Regular use of interdental brush can prolong the life span of implant tooth and keep the patients' teeth in good condition.

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.

This study identifies oral health behavior factors related to the health-related quality of life(EQ-5D) of adults. Three groups are analyzed, young adults(aged 19 to 39 years old), middle-aged(40 to 64 years old), and elderly(over 65 years old). By comparing the factors related to health-related quality of life by age, we will provide information for improving the overall quality of life, including oral health for current and future elderly. Using raw data from the 1st year(2016) of the National Health and Nutrition Survey, the oral health behaviors of the study subjects were compared. These included: the number of times teeth were brushed, the time brushing took place, the use of interdental care products, and whether they went for oral and examinations. There was a statistical significance in treatment experience and drinking habits. There was also a significant influence on the health-related quality of life across the age groups. Therefore, it is possible to improve the health-related quality of life, including oral health practices according to age. It will be necessary to develop and apply.

The present study was designed to grasp the oral health behavior practice levels and PHP index and gingival index of orthodontic patients' orthodontic related characteristics. A survey and oral examination were conducted for 206 orthodontic patients with fixed appliances. The collected data were analyzed with a t-test, one way ANOVA and stepwise multiple regression. Women were higher than men of the toothbrushing parts(p<0.05), toothbrushing frequency(p=0.001) and use of more oral hygiene products(p<0.01). As for the use of more oral hygiene products practice, it has higher when experience of more education(p<0.05), toothbrushing method practice difference when it comes to age(p<0.05). As for toothbrushing times, difference was purpose of orthodontics(p<0.05) and period of orthodontics(p<0.05) and orthodontics equipment(p<0.05). As for orthodontic equipment, conventional-ligating bracket high score compared to the self-ligating bracket with Buccal PHP index(p<0.001) and gingival index(p<0.05). The factors with lowest possible Buccal PHP index; when age is greater(p<0.05), toothbrushing method practice is higher(p<0.001) and when patients have self-ligating bracket(p<0.001). Education for the orthodontic patients on the oral health behavior practice should be carried out structurally to the group of patients who are 17 years old or younger, to the group with conventional-ligating bracket and to the men. Moreover, it is critical to ensure that there won't be oral health problem during on orthodontic period.

Background: Dental caries is mainly composed of various cellular components and is deposited around the tooth surface and gums, causing a number of periodontal diseases. Streptococcus mutans is commonly found in the human oral cavity and is a significant contributor to tooth decay. The use of antibacterial ingredients in oral hygiene products has demonstrated usefulness in the management of dental caries. This study investigated the anticaries effect of the ethanol extract of Terminalia chebula (EETC) against S. mutans and their cytotoxicity to gingival epithelial cells. Methods: The EETC was prepared from T. chebula fruit using ethanol extraction. Disk diffusion, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and colony forming unit (CFU) were analyzed to investigate the antimicrobial activity of the EETC. Glucan formation was measured using the filtrate of the bacterial culture medium and sucrose. Gene expression was analyzed using reverse transcription-polymerase chain reaction (RT-PCR). Cytotoxicity was analyzed via the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. Results: The antibacterial activity of the EETC was explored using disc diffusion and CFU measurements. The MIC and MBC of the EETC were 10 and 20 ㎍/ml, respectively. EETC treatment decreased insoluble glucan formation by S. mutans enzymes and also resulted in reduced glycosyltransferase B (gtf B), gtf C, gtf D, and fructosyltransferase (ftf), expressions on RT-PCR. In addition, at effective antibacterial concentrations, EETC treatment was not cytotoxic to gingival epithelial cells. Conclusion: These results demonstrate that the EETC is an effective anticaries ingredient with low cytotoxicity to gingival epithelial cells. The EETC may be useful in antibacterial oral hygiene products for the management of dental caries.
