Oral diseases have been reported to affect approximately 3.5 billion people worldwide, and in Korea, gingivitis and periodontal disease ranked first in the most frequent diseases from 2019 to 2021. Microorganisms that cause oral diseases include not only some bacteria such as Streptococcus mutans, Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus gordonii, Leptotrichia buccalis, Prevotella, and Treponema, but also fungi Candida albicans and archaea Methanobrevibacter oralis. In the process by which oral microorganisms cause periodontal disease, bacteria such as Streptococcus mutans first proliferate to form a biofilm, and then obligate anaerobes, opportunistic bacteria, and pathogens attach, proliferate and settles down, forming plaque in the subgingival area of the host with weakened immunity. In this way, various interactions within the community are important in causing oral disease. Furthermore, substances and inflammation resulting from oral microorganisms and oral diseases are closely related to the occurrence of digestive diseases, diabetes, cardiovascular diseases, cognitive function, rheumatoid arthritis, premature birth, and cancer, and vice versa.

This study examined the relationships among impaired fasting glucose (IFG), diabetes and periodontal disease. The data from 10,856 adults (aged over 19 years) was derived from the Fifth Korean National Health and Nutrition Examination Survey, which was conducted in 2010 and 2012. Adjusting the related confounders, multiple logistic regression analysis showed that periodontitis were related to gender, age, education level, smoking and diabetic status (p<0.001). These findings suggest that abnormal fasting glucose, which is a predisposing factor for diabetes mellitus, does not appear to be a risk indicator for periodontal disease. On the other hand, if patients do not take steps to prevent or delay diabetes, prediabetes is likely to develop into type 2 diabetes within 10 years. Therefore, patients with prediabetes need to undergo continuous examinations and management of periodontal disease.

To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.

This study was peformed in order to find out the relationship between the causing factors and the production of each gas 01 oral malodor, to contribute the oral malodor control at dental clinic as well as to establish the effective application of malodor control project for public oral health program 127 patients from 20 to 40 years old who had been visited for preventive dental cares were participated for the study. Such items as caries status, periodontal status, salivary flow, viscosity, pH. Snyder test, plaque deposit and tongue plaque were checked through the oral examination in order to find out the contributing factors Hydrogen sulfide, Methyl mercaptan, Di-methyl sulfide and Ammonia gas components were checked with Oral-Chroma and Attain, the oral malodor check units. Not only the corelation coefficiencies but also the multi-way variance analysis were calculated between each causing factor and each component of oral malodor gases to estimate the contributing factors of the oral malodor. 1. There was no relationship between the caries status and each component pf the oral malodor such as sulfur compound or Ammonia, both in laboratory test and VAS test (pF0.05). It revealed negative relationship between Hydrogen sulfide and FT(rM-0.1904. pE0.05) as well as the VAS and FT (rM-0.210. pE0.05). S0, it was estimated that the less oral malador was recognized when caries state changed to filled state in Hydrogen sulfide laboratory test or VAS test 2. High relationship was showed between salivary flow and Hydrogen sulfide (rM-0.183, pM0.039), Methyl mercaptan(rM-0.234, p-0.008). Dimethyl sulfide(rM-0.234, pM0.008) and Ammonia(-0.361. pM0.001) gas(pE0.05). 3. There was a high relationship between M-PHP(Modified-Patient Hygiene Performance Index) and tong plaque all kinds of sulfide(rM0.249. pM0.005). Ammonia gas component(rM0.232, pM0.009). 4. It was found that considerable relationship was appeared between the periodontal status and Ammonia gas (rM0.274, pM0.002), so, it should be needed to control Ammonia. Such dental Cares as the prevention or early treatment of periodontal disease and the accelerating the salivary flow as well as reducing the amounts and activities of filament or spiral typed oral micro-organism were recommended for adults, not only for dental care program at the dental clinics but also for public health programs, in order to promote the oral health and quality of file for individual and community peoples.

The purpose of this study was to examine the types of implant, the type of bone graft, periodontal status and the distribution of implant among patients in a region. The subjects in this study were 299 patients who received implant treatment Busan area. The number of their implants was 871 in total. The findings of the study were as follows: As for the type of implant, home-made implants accounted for 83.6 percent, and imported ones represented 16.4 percent. Regarding bone graft, The presence or absence of disease made a significant difference to that($x^2$=14.66, p<.01). As to periodontal status by gender, age and disease, the periodontal state was better among those who were female(y=-2.73, p<.01), who were younger(F=14.20, p<.001) and who had no disease(t=-4.67, p<.001). The intergroup gaps were statistically significant. Concerning the distribution of implant, The distribution of implant was statistically significantly different($x^2$=33.14, p<.01). Age made a statistically significant difference to that($x^2$=74.09, p<.001). As to links between periodontal status and the number of implant, The intergroup gaps were statistically significant($x^2$=38.28, p<.01).

The purpose of this study was to examine association between oral health status and perceived general health symptom. We analyzed 14,231 subjects who participated in Korea National Health and Nutrition Examination Survey (2007~2009). All individuals were examined by a questionnaire about socioeconomic history, smoking and drinking habit, the frequency of daily tooth brushing, the presence of regular dental visit, and EuroQol-5D. Dental survey was conducted to find the decayed, missing, and filled teeth (DMFT) index and community periodontal index. Subjects with perceived problem with mobility had higher DMFT index (odds ratio, 1.18, p<0.001). Subjects with with perceived problem with pain/discomfort had higher DMFT index (odds ratio, 1.16, p<0.001). Self-rating general health symptom was not associated with periodontitis (p>0.05). Perceived general health was associated with DMFT index. It is recommendable that we can use the perceived general health to predict oral health status.

Objectives: The purpose of this study was to investigate the effects of general and oral health on quality of life in the elderly living alone and with family. Methods: We analyzed data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. Distribution of the elderly living alone and with family based on the general characteristics and general and oral health was analyzed using complex-sample chi-square tests. Multiple logistic regression was used to analyze the factors affecting quality of life by calculating the 95% confidence intervals. Results: In the elderly living alone, the quality of life significantly correlated with restriction of activity, perceived general and oral health status, perceived stress, and speech difficulties. Further, in the elderly living with family, lower quality of life significantly correlated with restriction of activity, perceived health status, walking days per week, life time smoking history, Community Periodontal Index, and chewing and speech difficulties. Conclusions: The elderly are concerned with self-maintenance of general and oral health. Therefore, systematic policies related to health services need to be developed and operated at the national level. It is especially necessary to take social interest in the elderly living alone and a more continuous and professional approach in their health care.

This study selected 2,134 fertile women aged 20 to 44 years as the final study subjects using the 6th source data of the National Health and Nutrition Survey. The purpose of this study was to investigate the relationship between female characteristics, chronic diseases and oral health behavior, and the effects of each factor on periodontal diseases. There were statistically significant differences in age(p<0.001), education level(p<0.001), income(p<0.05), marital status(p<0.001), smokes(p<0.05) and pregnancy(p<0.001). Chronic disease factors showed statistically significant differences in hypertension(p<0.001), obesity(p<0.001), diabetes(p<0.001), hypercholesterolemia(p<0.05), hypocholesterolemia(p<0.001) and hypertriglyceridemia(p<0.001). Oral health behaviors were statistically significant in terms of toothache(p<0.05), orthodontic treatment(p<0.05) and chew discomfort(p<0.05). As a result of examining the risk factors affecting periodontal disease, the risk of chronic disease was 1.576 times higher in the obese group, and 2.569 times higher in the diabetic group than in the normal group. The subjective oral health status was 1.372 times higher for normal women and 1.614 times higher for bad women than for good ones. As a result, diabetes has shown the greatest risk among chronic diseases in women, and diabetes and obesity are highly relevant and therefore are considered important variables for the risk factors of dementia. In this regard, it is necessary to examine the risks of chronic and periodical diseases, expand oral health education programs for women's dental disease, and prepare oral health policies.
