Objectives: This study investigated the relevance of dietary behavior and oral management for oral heath in adults to extend the recognition of the importance of food intake in oral health and to provide basic information for oral health management. Methods: A survey and clinical assessment were conducted for 119 adults over 20 years of age. The chi-square test and logistic regression analysis were carried out using SPSS Statistics 20.0. Results: Gingivitis was influenced less when ham and sausage in the sub-area of meat, fish, egg, and bean were consumed once a week rather than the cases when consumed rarely (3.47 times) or when consumed two times or more a week (7.87 times) (p<0.05). Periodontitis was influenced more in the groups of 30s and 40s age than in that of over 50 years of age (14.97 times, 7.73 times) and in the group without drinking experience than in group with that (4.17 times) (p<0.05). Conclusions: The results verified the close relationship between food intake frequency and oral health in patients with periodontitis and gingivitis. Thus, it would be necessary to study the relationship between dietary behavior and oral health continuously.

Background: This study aimed to investigate the association between physical activity and periodontitis based on depression status in a representative sample of Korean adults. Methods: A total of 12,689 subjects who participated in the 7th Korea National Health and Nutrition Examination Survey (2016-2018) were examined. Depression was defined as a PHQ-9 score ≥ 10. Periodontal status was assessed using the community periodontal index, with periodontitis defined as a code ≥ 3. Physical activity categories were divided into a physical activity group and a non-physical activity group, considering the number of days and minutes spent on moderate and vigorous activities. Moderate activity was defined as causing slight breathlessness or a slightly elevated heart rate, while vigorous activity was defined as causing significant breathlessness or a rapid heart rate. Multivariable logistic regression analyses were adjusted for sociodemographic variables (age, sex, education level, and household income), oral and general health behaviors (use of floss and interdental proximal brush, current smoking), and systemic health status (diabetes and hypertension). All analyses utilized a complex sampling design, and subgroup analysis was performed to estimate associations stratified by depression (PHQ-9 ≤ 9 and ≥ 10). Results: Multivariable regression analysis revealed that among participants with depression, those who did not engage in physical activity were 2.65 times more likely to have periodontitis (odds ratio = 2.65, 95% confidence interval = 1.17-6.01). Conclusion: The study findings suggest that individuals who participate in any form of physical activity may be significantly less likely to develop periodontitis, particularly within the group experiencing depression.

The purpose of this study was to examine the relationship between vitamin D and periodontal diseases based on the raw data of the 5th National Health & Nutrition Examination Survey of 2010. The subjects in this study were 1,327 people, and those whose data on major variables were missing and who suffered from diabetes and/or osteoporosis were excluded. As for data analysis, R2.15.1 program and PASW Statistics 18.0 were utilized. The findings of the study were as follows: 1. As for all the respondents aged 50 and up, there was no significant relationship between vitamin D and periodontal diseases. 2. As for the post-menopausal women including the women who underwent bilateral ovariectomy, the vitamin D-deficit group 1 (<10) were 6.66-fold more likely to suffer from periodontal diseases than the vitamin D-sufficient group (${\geq}30$) (OR, 6.66; 95% CI, 1.004~44.19). The above-mentioned findings ascertained that vitamin D had a significant negative correlation to periodontal diseases among the post-menopausal women including the women who underwent bilateral ovariectomy. This finding should be taken into account in terms of the prevention and management of periodontal diseases.

Intellectual disability is an imperfect disorder in which mental development is permanently retarded and development of intellectual ability is inadequate. Having intellectual disabilities makes it difficult to handle their own work and adapt to social life. For this reason, it is difficult to hygienically manage the patient's oral condition, multiple caries are easily observed, and the periodontal disease incidence rate is high. The patient in this case is a 33-year-old female with a mental retardation first grade who had a problem with meals. In first visit, Patients had decreased occlusal vertical dimension and posterior bite collapse due to periodontitis and multiple caries. This case reports a satisfactory functional and esthetic results by reconstructing occlusion using partial removable dental prosthesis.

Reports on the comparison of clinical effect between non-surgical and surgical therapy, and the change of the clinical parameters during maintenance phase have been rarely presented in Korea. This study was to observe the clinical changes during maintenance phase of 6 months in patients with chronic periodontitis treated by non-surgical or surgical therapy in Department of Periodontics, Chonnam National University Hospital. Among the systemically healthy and non-smoking patients with moderate to severe chronic periodontitis, twenty eight patients (mean age: 47.5 years) treated by non-surgical therapy (scaling and root planning) and nineteen patients (mean age: 47.3 years) treated by surgical therapy (flap surgery) were included in this study. The periodontal supportive therapy including recall check and oral hygiene reinforcement was started as maintenance phase since 1 month of healing after treatment. Probing depth, gingival recession. clinical attachment level and tooth mobility were recorded at initial, baseline and 1, 2, 3 and 6 month of maintenance phase. The clinical parameters were compared between the non-surgical and surgical therapies using Student t-test and repeated measure ANOVA by initial probing depth and surfaces. Surgical therapy resulted in greater change in clinical parameters than non-surgical therapy. During the maintenance phase of 6 months, the clinical effects after treatment had been changed in different pattern according to initial probing depth and tooth surface. During maintenance phase, probing depth increased more and gingival recession increased less after surgical therapy, compared to non-surgical therapy. The sites of initial probing depth less than 3 mm lost more clinical attachment level, and the sites of initial probing depth more than 7 mm gained clinical attachment level during maintenance phase after non-surgical therapy, compared to surgical therapy. Non-surgical therapy resulted in greater reduction of tooth mobility than surgical therapy during maintenance phase. These results indicate that the clinical effects of non-surgical or surgical therapy may be different and may change during the maintenance phase.

Parkinson's disease is a neurological disorder characterized by tremor, bradykinesia, akinesia, postural instability, and muscular rigidity, which is caused by the depletion of neurotransmitters such as dopamine. Cooperative dental treatment is more challenging because of tremor of Parkinson's disease. In this case, a 47-year-old Parkinson's disease patient with chronic periodontitis was treated with full-mouth rehabilitation using conventional fixed prostheses and implant fixed partial denture, which attained satisfactory outcomes functionally and esthetically. Short term periodic follow-ups will be needed with consideration for the characteristics of Parkinson's disease such as decreased manual dexterity.

The aim of this study was to identify an effective control method of metabolic syndrome (MS) and oral diseases by investigating relationship between of MS and periodontal disease, tooth loss of the adult men and woman. We analyzed and concluded as follows, using a nationwide representative sample, in 8,225 middle senior citizens based on raw data of the 5th National Nutrition Survey in 2010, 2012. The data were analyzed by descriptive statistics, chi-squared test, and logistic regression using SAS ver. 9.2 program. The results are as follows, for correlation of metabolic component to periodontal disease, it was found that in men, the periodontal disease odds ratio of the group with abnormal fasting blood glucose increased 1.27 fold (95% confidence interval [CI], 1.04~1.54), and in woman, the odds ratios of the group with abnormal high density lipoprotein cholesterol increased 1.45 fold (95% CI, 1.22~1.72) and the odds ratio of the group with abnormal obesity increased 1.44 fold (95% CI, 1.17~1.77). For correlation of MS to periodontal disease, it was found that the odds ratio of periodontal disease in the woman at-risk group increased 1.55 fold (95% CI, 1.19~2.01) and that of the group with MS increased 2.25 fold (95% CI, 1.68~3.02). For correlation of woman's metabolic component to missing teeth, it was found that the odds ratio of group with abnormal blood pressure increased 1.41 fold (95% CI, 1.10~1.82). For correlation of woman's MS to missing teeth, it was found that the odds ratio of missing teeth in the group with MS increased 1.48 fold (95% CI, 1.07~2.04). It is considered that a public health project comprising preventive and systematic disease management is necessary for controlling MS and oral disease. The findings of the study are expected to lay the foundation for the development of oral health promotion programs.

Background: This study aimed to investigate the changes of the amount of P. gingivalis in saliva by professional preventive treatment of periodontal disease by dental hygienists. Methods: A total of 109 subjects participated in this study with informed consent. The control group (38 subjects) performed oral hygiene management individually. The periodontal treatment group (35 subjects) underwent root planning once every 3 weeks for a total of 4 times. The professional periodontal prevention group (36 subjects) underwent interdental cleaning and professional tooth brushing once every 3 weeks for a total of 4 times. Paired T test and analysis of variance were performed to compare the difference among the groups in the amount of P. gingivalis. Results: The copies of P. gingivalis in the professional periodontal prevention group decreased from 773.62±1,198.09 to 241.40±430.40 after treatment significantly. The control group decreased from 525.22±582.54 to 244.29±385.88 after treatment. The periodontal treatment group showed insignificant change of P. gingivalis. Conclusions: This study showed the professional periodontal prevention was more effective than periodontal treatment in decrease of P. gingivalis.
