Although the Korea National Health and Nutrition Examination Survey (KNHANES) calculates oral health functional restriction rate and chewing discomfort rate every year, these two indicators are not all indicators of oral health. Therefore, indicators are needed to subdivide by age group and cover dental caries, periodontal disease, remaining teeth, and oral care use. The purpose of this study is to identify the key indicators of oral health in mature and middle age. The average number of existing natural teeth, the rates of 20 or more natural teeth, complaints of chewing discomfort, oral examination, periodontal disease and dental caries, were analyzed using KNHANES VI (2013-2015) as a complex sample. In the age group between 40 and 64, there were 25.2 natural teeth remaining, 91.4% natural teeth retention rate, 23% chewing discomfort rate, 34.7% oral examination rate, 38.7% periodontal disease prevalence, 6.46 the number of caries experience teeth, 21.4% interdental brush usage rate.

Objectives : This research aims to analyze the relationship between the state of mental illness and oral health management of mental patients in mental health care institutions. Methods : The data were randomly selected from 474 patients in mental health care institutions. and analyzed by SPSS WIN 12.0 program. Results : Schizophrenia accounted for 79.5%(337 patients) ; alcohol dependency, 5.3%(25 patients) ; mental retardation, 2.7%(13 patients) ; mental development disorder, 3.0%(14 patients) ; mental delusion and dementia, 7.6%(36 patients). Those who were in 40s had the highest dental caries of 3.95 and the highest remaining teeth of 26.76 were shown in the 20s. The correlation between remaining teeth and mental retardation was the highest, measuring 22.38(p<.05). Those who were in 70s had the serious periodontal condition that accounted for 41.3%(12 patients)(p<.05). The correlation coefficient for all factors-dental caries, remaining teeth, need for scaling, and periodontal condition-between mental illness condition and oral health were all positive(p <.05). The regression analysis resulted in the formula Y(mental health condition)=2.999+0.166(dental aries)-0.028(remaining teeth). Conclusions : Those who had mental illness had very poor and serious dental caries and periodontal diseases, so it is necessary to manage the dental health care for the mentally ill patients.

Korean society is experiencing a very rapid change in population aging. Oral diseases, including dental caries and periodontal disease, are usually cumulative and make oral health worse with age. Preventing tooth loss through the prevention and treatment of caries and periodontal diseases are essential for retaining oral function later in life. This study aimed to identify the trend in oral health status among elderlies over 65 years old, using major oral health indicators of Health Plan 2020. The fifth, sixth, and seventh Korea National Health and Nutrition Examination Survey (KNHANES V, VI, VII) were used in the present study to estimate the number of remaining natural teeth, the rate of 20 or more natural teeth, the rate of chewing difficulty, and the rate of oral health check-up of elderly. The number of remaining natural teeth increased from 15.6 in 2010 to 17.1 in 2015, and the rate of 20 or more natural teeth also increased from 45.8% in 2010 to 53.7% in 2015. The rate of chewing difficulty was similar but declined a little from 44.3% in 2010 to 42.9% in 2017. Finally, the rate of oral health check-ups of the elderly increased significantly from 12.2% in 2010 to 21.1% in 2017.

One of the best way to prevent dental caries and periodontal disease is removing dental plaque. Toothbrushing is also one of the crucial ways to gel rid of dental plaque and improve dental hygiene. The purpose of th is study was to examine how many bacteria were attached to toothbrushes used by dental palque acidogenecity and related behaviors to toothbrush use. Subjects in this study were 30 college students in their twenties, on whom a survey was conducted to find out how they cleansed their toothbrushes, how long they cleaned toothbrushes after brushing, and how to keep them. And then dental palque acidogenecity by caries activity test was implemented and the number of bacteria attached to their toothbrushes was tested. The findings of the study were as follows : 1. Concerning correlations between dental palque acidogenecity and the number of remaining bacteria in the toothbrushes used by students, the number of bacteria was lower in the group of students with no caries activity than in the group with mild caries activity. 2. As for relations between the way of cleansing toothbrushes and the number of bacteria, there was no statistically significant gap between the group of students who wetted their toothbrushes with water and rubbed the heads of them and the group of students who just only wetted their toothbrushes with no further actions. 3. Regarding the relationship of toothbrush cleansing time to the number of bacteria, the number of bacteria was lower in the group of students who cleansed their toothbrushes for 15 seconds or more. 4. As to the influence of the number of toothbrush used by students, there was no significant difference between the group using just one toothbrush and the other group using two or more toothbrushes. 5. As for correlations between the way of keeping toothbrushes and the number of bacteria, no significant gap existed between the group thai kept their toothbrushes separately and the other that didn't.

Objectives: The purpose of the study is to investigate the relationship between oral health status and body mass index (BMI) in adults over 65 years old. Methods: The study subjects were 4,550 adults over 65 years old from the 5th Korea National Health and Nutrition Examination Survey(KNHANES V) in 2010-2012. Mastication-related oral health status included the number of remaining teeth, and mean number of decayed, missing, and filled permanent teeth(DMFT). Body mass index(BMI, $kg/m^2$) was categorized as underweight(<18.5), normal weight (18.5-22.9), overweight(23.0-24.9), and obese(${\geq}25.0$). Multinomial logistic regression analysis was performed to examine the association of BMI categories with the number of remaining teeth and DMFT. Results: The mean number of DMFT was highest($13.0{\pm}0.7$) in the underweight group and lowest($8.8{\pm}0.3$) in the obese group. Those having less favorable masticatory ability, and fewer number of remaining teeth and no prosthesis, tended to be underweight. Those having a higher number of remaining teeth and prosthetic teeth tended to be overweight or obese. In the multinomial logistic regression analysis, compared with those having 20 or more remaining teeth, including prosthetic teeth, those having less than 20 remaining teeth and no prosthesis had 4.48 times higher odds ratio of being underweight. DMFT was positively associated with underweight, while negatively associated with overweight or obesity. Conclusions: The masticatory ability and dental caries prevention maintained the healthy body weight in adults of old age.

An epidemiological survey was carried out to identify the serotypes of Streplococcus mutans isolated from carious lesions of 65 caries-active subjects(CAS) and sound tooth surfaces of 40 caries-free subjects(CFS). The autoclaved antigen extract was performed on each isolate, and then, serotypes of the isolates were determined in agar-gel immunodiffusion test. The results were as follows: 1. S. mutans was found in 78% of the samples of CAS, and of CFS. The difference of isolation frequency between CAS and CFS was not observed. 2. Only one serotype per single subject was detected in 61% of total samples, in remaining 39% of samples two or more serotypes were detected. 3. In 41.2% of CAS samples plural serotypes of S. mutans were found, whereas 35.5% of CFS samples showed plural serotypes distribution. 4. The most frequently identified serotype in each subject was serotype c; 69.5% of subjects harbored serotype c S. mutans. Serotype d was next most frequently isolated from subjects, comprising 23.2%. 5. Serotype c strain was found in 64.7% of CAS, 77.4% of CFS. 6. Of the isolates from CAS and CFS, serotype c was most commonly found, comprising 48.8%, serotype d was found in 16.3%, serotypes f. e, and g comprising 13.2%, 9.3%, and 7.8% respectively. Serotypes a and b were also found but in far lower frequencies(2.3%, 0.8%). 7. Serotype c strains were more found in CFS than in CAS, but serotypes d and e were more found in CAS.
