This study investigated the current oral health conditions of the elderly at home and welfare facilities in their age over 65 years around some rural areas in Gangwon province, which would expect the fewer medical benefits even with lower interest than urban areas, despite of relatively high ratio of elder populations, so that it could prepare a basic document necessary to determine certain planned quantification for the benefit of elder's oral healthcare. As of the end of December 2004 both 50 elders at home and 50 elders at welfare facilities were randomly sampled in their age over 65 years in Samcheok city. As a result of this study, it was found that the elders at welfare facilities scored 15 pts. in DMFT index level typical of oral health conditions, which was higher than the elders at home. In addition, the elders at welfare facilities scored 26.0% in the coexistence of immobile bridge and partial denture higher than the elders at home with regard to the presence of intraoral prosthetic appliance. The results of analyzing the difference in the one-year dental visiting experience of respondents hereof showed that the elders at home were relatively more in ratio(62.0%) than those at welfare facilities, while many of the former group(38.0%) had relatively more handicap in masticatory movement than the latter one with regard to the conditions of dental prosthesis in use. Besides, many of the elders at facilities(30% or more) felt subjective symptoms of periodontal disease including bleeding or swelling, which indicates higher ratio than the elders at home. Finally, the elders at home used to brush their teeth at more frequency on a daily basis than those at facilities, while the latter group suffered general body disease more than the former group. Summing up, it is concluded that a formulated oral healthcare system will become more needed in near future than now for the benefit of the elderly living in welfare facilities, while nationwide policy-level supports would be urgent for them in the aspect of national welfare.

Recently multicultural female population is increasing of our country as international marriages increase. With oral care programs, conducting follow-up surveys on multicultural women's oral health condition to figure out the condition and examining improvements and related factors, it tried to contribute to building oral care programs for the future of multicultural families. The study participants were recruited from multi-cultural family center in a metropolis, they were treated their oral conditions at local dental clinics during a year. All participants were 608 people, and among them, one year follow-up sample was 40 women. An interview questionnaire was used to collect information on socioeconomic level and general characteristics related to oral status, through oral examination were conducted to obtain dental caries experience and periodontal conditions. The statistical analysis was done by using the SPSS 20.0 program. Comparing the results between before and after oral health program for an year, DMFS, DS, FS, DT, FT and CPI were significantly decreased during a year. The present study increases interest about multicultural women and family and we look forward to using it as basic data for oral health promotion.

Individuals with cognitive disabilities face many barriers to oral care, often suffering from partial or complete edentulism. While the use of implant reconstruction is becoming more common in general population, such care is still being used infrequently in individuals with intellectual impairment. Because of the patients'oral hygiene practice is poor, special need is required for prosthetic design. These two cases were restored by prostheses using implants. Prosthetic modalities were different but the implants were fully osseointegrated, presenting satisfactory functional and esthetic conditions without clinical or radiographic signs of alterations or pathologies. We report that it is good for cognitive disabilities to give prosthetic treatment using implants.

The prevalence of oral cancers (OC) is high in Asian countries, especially in South and Southeast Asia. Asian distinct cultural practices such as betel-quid chewing, and varying patterns of tobacco and alcohol use are important risk factors that predispose to cancer of the oral cavity. The aim of this review is to provide an update on epidemiology of OC between 2000 and 2012. A literature search for this review was conducted on Medline for articles on OC from Asian countries. Some of the articles were also hand searched using Google. High incidence rates were reported from developing nations like India, Pakistan, Bangladesh, Taiwan and Sri Lanka. While an increasing trend has been observed in Pakistan, Taiwan and Thailand, a decreasing trend is seen in Philippines and Sri Lanka. The mean age of occurrence of cancer in different parts of oral cavity is usually between 51-55 years in most countries. The tongue is the leading site among oral cancers in India. The next most common sites in Asian countries include the buccal mucosa and gingiva. The 5 year survival rate has been low for OC, despite improvements in diagnosis and treatment. Tobacco chewing, smoking and alcohol are the main reasons for the increasing incidence rates. Low socioeconomic status and diet low in nutritional value lacking vegetables and fruits contribute towards the risk. In addition, viral infections, such as HPV and poor oral hygiene, are other important risk factors. Hence, it is important to control OC by screening for early diagnosis and controlling tobacco and alcohol use. It is also necessary to have cancer surveillance at the national-level to collect and utilise data for cancer prevention and control programs.

Objectives : This study intended to figure out illegal treatment by unlicensed person in dental area and factors, which were considered as user's position on the basis of the local community investigation of health conditions in chungbuk provinces in 2008. Methods : This study used chi-square test and complex sample design of multi-variate logistic regression analysis to question 12,443 peoples who have experience on illegal dental treatment. Results : Multi-variate logistic regression analysis results showed that factors having related to illegal dental treatment are sex, age, education standards, subjective awareness of oral health condition, drinking experience of lifetime, unmet need of dental treatment, chewing difficulty, use of dentures, experience of scaling and the use of interdental care instrument. Conclusions : As a result of this study, in order to root out illegal dental treatment, we need to expand the breadth of health insurance coverage so that it can reduce the burden of dental expenses. Moreover, we need to set out health service of public oral health to inform the importances of maintaining good oral health and the problems of illegal dental treatment by unlicensed person.

To assess the association between oral health and general health, this study examined the relationship between chewing difficulty and twelve chronic health conditions such as hypertension, hyperlipidemia, diabetes, cerebro- and cardiovascular disease, musculoskeletal disease, respiratory disease, eye/nose/throat disease, stomach/intestinal ulcer, renal dysfunction, thyroid disease, depression, and cancer in Korea. The study population was 3,066 elders aged 65 years old and more from the fourth Korean National Health and Nutrition Examination Survey. Chewing difficulty was measured on a 5-point Likert scale. Chronic conditions were assessed by self-reported questionnaire. Confounders were age, gender, education, income, smoking, drinking, and obesity. Chi-square test, general linear model, and multiple logistic regression model were done with complex sampling design. Musculoskeletal disease (adjusted odds ratio=1.33), respiratory disease (adjusted odds ratio=1.52), and cancer (adjusted odds ratio=1.58) were independently associated with chewing difficulty. Multiple chronic conditions with more than 4 chronic disease showed significant association with chewing difficulty (adjusted odds ratio=1.37).

The purpose of this study was to evaluate smoking patterns, oral health behavior and perception of dental healthcare of military personnel in the South Korea Army. All 367 subjects were surveyed by the structured questionnaires with convenience sampling method. The questionnaires were consisting of 22 items. Depending on the conditions of military training, the distribution and differences of smoking patterns and oral behaviors were evaluated by frequency test, Weighted Kappa, Paired t-test and ANOVA. The differences of oral health perception on smoking were demonstrated by Mantel-Haenszel Chi-square test. In addition, Generalized Estimating Equation (GEE) was used to estimate the effects of oral behavior for the conditions of military training and smoking. The number of cigarette during military training period was similar to that during non-military training (p=0.109). The perception of smokers such as smoking effect on oral health, oral health and systemic health, and need of education for smoking cessation was significantly lower than non-smokers (p=0.0095, p=0.0007, and p<0.0001). The probability that toothbrush frequency per day was only one was associated with higher during military training period than non-military training (OR=9.29, 95% CI 5.05-17.07). Moreover, the probability that hours of toothbrush were less than one minute was associated with higher during military training than non-military training (OR=2.19, 95% CI 1.78-2.71). To improve knowledge, attitude, and behavior of oral health for the members, the army needs to develop oral health education and tobacco cessation programs. In particular, motivation and practice for oral health care are required to improve poor oral health behavior during the military training.

The human oral cavity contains a highly personalized microbiome essential to maintaining health, but capable of causing oral and systemic diseases. Thus, an in-depth definition of "healthy oral microbiome" is critical to understanding variations in disease states from preclinical conditions, and disease onset through progressive states of disease. With rapid advances in DNA sequencing and analytical technologies, population-based studies have documented the range and diversity of both taxonomic compositions and functional potentials observed in the oral microbiome in healthy individuals. Besides factors specific to the host, such as age and race/ethnicity, environmental factors also appear to contribute to the variability of the healthy oral microbiome. Here, we review bioinformatic techniques for metagenomic datasets, including their strengths and limitations. In addition, we summarize the interpersonal and intrapersonal diversity of the oral microbiome, taking into consideration the recent large-scale and longitudinal studies, including the Human Microbiome Project.

Halitosis is defined as a nasty odor emanating through the mouth and is primarily related to the enhanced concentration of volatile sulfur compounds (VSCs). VSC measurements have been commonly used for experimental comparison and clinical diagnosis. As quantitative methods for comparative analyses of oral malodor, gas chromatography devices have been most commonly used to quickly and easily determine the concentration of several gas components of VSCs, which are agents primarily responsible for halitosis. The concentrations of VSCs fluctuate dynamically depending on contributing factors, including various oral/systemic conditions, intake of medicine and food/drink, oral hygiene, and even routine daily activities. Therefore, the exact analysis of VSCs requires the appropriate standardization of not only exact measurement techniques but also participant conditioning with scientific considerations. Thus, this paper describes the experimental standardizations commonly recommended in previous literature and their scientific background.

Objectives: This study aimed to assess the association between the use of dentures by the elderly and the prevalence of depression by using the original data from the 2017 Community Health Survey as basic data for the promotion of oral health and oral health policy development in the elderly. Methods: The study subjects were 67,835 elderly over 65 years of age. The raw data were collected from 2017 Community Health Survey in Korea Center for Disease Control and Prevention. Results: Among the demographic and sociological characteristics, the higher the age, the lower the educational level, the worse the subjective health level, and the higher the denture use. The higher the age, the lower the education level, the lower the income level, the worse the subjective health level, the more stress they have, the more sleep time, and the higher the prevalence of depression. The association between the use of dentures and the prevalence of depression was 1.071 times higher than that of not using dentures, and it was found that the prevalence of depression was affected. Conclusions: As a result, it was confirmed that the use of dentures influenced the prevalence of depression. Institutional support will be needed to establish a national-level prevention policy that can maintain and promote healthy oral conditions and prevent the need dentures in the elderly.
