Occupational Dentistry was introduced in Korea about 70 years ago. During the colonial period occupied by Japan till 1945, there were few documents about industrial dentistry, furthermore most cases of occupational diseases and accidents might have been concealed intentionally by the colonial government. After being an independent country, several dentists made efforts to set up 'Preventive Dentistry for Workers' performing specific oral health surveys, even though which were stopped by Korean War. In 1960s' and 1970s', some investigations of oral status were carried out intermittently for specific small groups;white-collar workers, mentally retarded person, buddhist monks and crews of ocean liners. At the same time there was important study in Korean history of occupational dentistry, which was 'a comparison of the oral hygiene conditions in the female workers of a spinning factory at intervals of 30 years.' In 1980s', young researchers began to give attention to erosion of the teeth due to sulphuric acid in the acid-related industry and dental caries due to sugar and flour in the sweets industry. After being democratic labor union movement activated in 1987, hidden and suppressed occupational diseases under the military dictatorship were exposed and flushed in the newspapers. It was shocking for all people that 15-year old boy had been dead due to mercury intoxication after 3-month employment in 1988. In 1990s', the activity for studying oral status of workers in their workplaces was launched and 'Occupational Accidents and Diseases in Oral and Maxillofacial Field' was published. And also The Korean Association of Occupationl Dentistry was established. Oral health examination of workers at the time of employment and of workers exposed to 5 special chemicals at the time of routine special health examination was adopted in 1992, and epocally oral health examination was also included in periodic routine examination of workers' health in 1995. So, occupational dentistry in Korea should cope with the changing needs of working environment and the altering scheme of health examination.

This study examined the oral health knowledge of childcare teachers and their awareness of the prevention effects against dental caries. The subjects in this study were 433 childcare teachers in Seoul, Gyeonggi Province, Busan and South Gyeongsang Province, on whom a survey was conducted for five months, beginning in March, 2013. Hospitals (56.6%) were the most common route by which the childcare teachers acquired oral health knowledge. Regarding the distribution of the correct answers on oral health knowledge, every teacher gave the correct answer to the item "When a tooth comes out, it should be kept in milk and then be brought to a dental clinic," and the smallest number of them (35.1%) gave the correct answer to the item "When a tooth comes out, it should be washed with water." Concerning the level of oral health knowledge, the respondents, who worked in Busan and South Gyeongsang Province (p<0.001), who worked in childcare centers with more children (p<0.001), who were younger (p<0.001), and who were junior college graduates (p=0.002) had better oral health knowledge. In regard to the awareness of the prevention effects against dental caries, the respondents who were older (p<0.001) and who were married (p=0.002) were more aware of the prevention effects. According to position and career, teachers who were assistant principals (p=0.023) and had worked for 10 years or more (p=0.009) were more aware of the effects. Therefore, child care teachers should acquire accurate knowledge to improve the oral health of children, and regular training programs for age and education are needed.

This study was conducted to investigate the status of oral health behavior according to economic inequality in Korea. Raw data for the 3rd year (2015) of the 6th national health and nutrition survey were analyzed. Among surveyed individuals, adults over the age of 19 were designated as research subjects. The results indicated that a smaller 'house income' was associated with a higher supply and demand experience for basic living and a higher DMFT. Additionally, a higher DMFT was associated with a lower 'house income', lower 'education level', and the 'experience of basic living security received'. Oral health behavior inequality was caused by economic inequality. Overall, these results indicate that it is necessary for the oral health service of vulnerable groups to strengthen preventive activities through comprehensive arbitration policies regarding the social decision factors of public health projects.

Dementia is an umbrella term that describes the loss of thinking, memory, attention, logical reasoning, and other mental abilities to the extent that it interferes with the activities of daily living. More than 50 million individuals worldwide live with dementia, which is expected to increase to 131 million by 2050. Recent research has shown that poor oral health increases the risk of dementia, while oral health declines with cognitive decline. In this narrative review, the literature was based on the "hypothesis" that dementia and oral health have a close relationship, and appropriate oral health and occlusal rehabilitation treatment can improve the quality of life of patients with dementia and prevent progression. We conducted a literature search in PubMed and Google Scholar databases, using the search terms "dementia," "major neurocognitive disorder," "dentition," "occlusion," "tooth loss," "dental prosthesis," "dental implant," and "occlusal rehabilitation" in the title field over the past 30 years. A total of 131 studies that scientifically addressed dementia, oral health, and/or oral rehabilitation were included. In a meta-analysis, the random effect model demonstrated significant tooth loss increasing the dementia risk 3.64-fold (pooled odds ratio=3.64, 95% confidence interval [2.50~5.32], P-value=0.0348). Tooth loss can be an important indicator of cognitive function decline. As the number of missing teeth increases, the risk of dementia increases. Loss of teeth can lead to a decrease in the ascending information to the brain and reduced masticatory ability, cerebral blood flow, and psychological atrophy. Oral microbiome dysbiosis and migration of key bacterial species to the brain can also cause dementia. Additionally, inflammation in the oral cavity affects the inflammatory response of the brain and the complete body. Conversely, proper oral hygiene management, the placement of dental implants or prostheses to replace lost teeth, and the restoration of masticatory function can inhibit symptom progression in patients with dementia. Therefore, improving oral health can prevent dementia progression and improve the quality of life of patients.
