Objectives: This study was conducted to identify the relations between multiple chronic diseases and peridontal diseases in Korean adults. Methods: A total of 4,142 cases was set for analysis, who aged 35 and over and finished with the third year health survey and oral health check-up of the fifth Korea National Health and Nutrition Examination Survey(2012). Peridontal disease was defined if community periodontal index(CPI) was 3(formation of paradental cyst of more than 4mm) or 4(formation of paradental cyst of more than 6mm). Results: The subjects consisted of 48.5% male and 51.5% female. The prevalence rate of peridontal disease was found to be 30.1% in total. In peridontal disease the more the age increased, and the lower the education level and income level as well as the more where the residential area was rural, the higher the prevalence rate was(p<0.01). According to the number of multiple chronic conditions the prevalence rate of periodontal disease accounted for 27.8%, 31.9%, 33.1%, and 35.2% when there were 0, 1, 2, and 3 or more chronic diseases respectively. As a result of logistic regression analysis, gender, age, education level, residential area, current smoking, and use of oral hygienic products were found to be significant factors on peridontal disease. Conclusions: This research revealed the prevalence rate of peridontal disease was 30.1% in Korean adults and health behaviors affecting on periodontal disease were more significant.

Objectives: This study investigated the relationship between the Korean healthy eating index (KHEI) and periodontal disease in the Korean adult population. Methods: The data used in the analyses were obtained from the seventh Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed by chi-square tests and t-test. Multiple regression analysis was also performed to assess the association between KHEI and periodontal disease. Statistical significance was set at p<0.05. Results: Multiple logistic regression analysis adjusted for socioeconomic variables showed that medical and health behavior variables were significantly related to the KHEI 1 (<63.7, odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.03-1.46), KHEI 2 (63.7-79.9, OR: 1.14, 95% CI: 0.97-1.34), and risk for periodontal disease. Conclusions: The results showed a significant association between the KHEI and periodontal disease in the Korean adult population.

The purpose of this study was to analyze factors affecting the health behaviors and urinary tract tests of adults and their effects on periodontitis by using raw data from the 6th National Health and Nutrition Survey (1st, 2nd, 3rd year). The subjects were 40 years older who had oral examination and urine tests such as glycosuria and ketonuris. The final 11,036 subjects were analyzed using SPSS. ${\chi}^2-test$ and logistic regression analysis were used to analyze the demographic characteristics, health behaviors, and differences in urine levels and presence or absence of periodontitis. There was statistically significant difference between the urine test values and the incidence of periodontal disease in urine glucose and proteinuria. Risk factors were male, age, income and education level, rural, smoking, obesity, urine glucose. These results suggest that improvement of health behavior and aggressive management of systemic disease factors are necessary and development of management and preventive program of Periodontitis is necessary.

Purpose: The current study was designed to investigate the relationship of dietary calcium and riboflavin and their main dietary source (milk and dairy products) with the risk of periodontitis using data from 2007 to 2010 Korea National Health and Nutrition Examination Surveys. Methods: A total of 1,690 adults aged ${\geq}40$ years were included. We used results of dental examination regarding all sextant information on probing depth of at least two index teeth, nutritional assessment by a single 24-hour dietary recall, and demographic and medical information. The periodontitis group was defined as those who had 3-4 points, and the normal group was defined as those who had 0 points of Community Periodontal Index at all locations of six examination sites using a probe. Results: Using multiple logistic regression analysis, after adjustment for age, body mass index, energy intake, income, smoking, and alcohol drinking, we found an inverse relationship between consumption of dairy products and risk for periodontitis (OR: 0.465, 95% CI: 0.224-0.964) and between dietary riboflavin intake more than the estimated average requirements and risk for periodontitis (OR: 0.535, 95% CI: 0.300-0.954) in males. Conclusion: Adequate intake of milk dairy products and riboflavin may be recommended for prevention of periodontitis in the Korean male population.

There is little evidence on the effects of environmental tobacco smoke (ETS) on prevalence of periodontal disease. The aims of this study were to explore the trends of prevalence of periodontal disease and types of exposure to smoke, including ETS according to the survey year, identify factors affecting periodontal disease, and compare the effect size of periodontal disease between active smokers and secondhand smokers. Data on 11,643 individuals were obtained from the fourth and fifth Korean National Health and Nutritional Examination Surveys. Information on exposure to ETS at home and work was self-reported. Severity of periodontal disease was evaluated using the community periodontal index. A multivariate logistic regression analysis was performed to model periodontal disease using types of smoking and the survey year. Overall, the prevalence of periodontal disease was 26.0% (n=3,029) and about 9% of the study population were secondhand smokers. The prevalence of periodontal disease among smokers was significantly increased according to smoking types by year. Active smokers showed a statistically significant adjusted odds ratio (aOR) for having periodontal disease except in the year 2007, whereas secondhand smokers had significant associations only in 2010 (aOR, 1.68; 95% confidence interval, 1.05 to 2.70) compared to non-smokers. For secondhand smokers, the statistical relationship of predicting periodontal disease was weaker than that of active smokers. However, ETS should separately be considered as an important risk factor for periodontal disease. This study suggested the need for further investigation of the impact of ETS on prevalence of periodontal disease using in-depth research designs and objective measurements for assessing periodontal disease and ETS.

수직 치근파절은 특이성을 나타내지 않기 때문에 치과의사가 정확한 진단을 하기 어렵다. 따라서 수직 치근파절의 임상적 특징, 진단적 증상을 파악하여 향후 근관치료된 치아나 치료되지 않은 치아에서 수직 치근파절의 유발인자와의 관련성 및 고찰을 통해 수직 치근파절의 예방 및 치료에 응용할 수 있을 것으로 생각된다. 연구대상은 조선대학교 부속치과병원 치주과에 내원한 환자 중 최근 2년간 144명의 환자에서 근관치료를 받았거나 받지 않았던 치아 중 임상적 및 방사선학적으로 수직 치근파절로 진단된 156개의 증례를 대상으로 하였다. 모든 불확실한 증례에서 수직 지근파절의 최종 진단은 외과적 탐지를 통해 이루어졌고, 금이 간 치아와 관련될 수 있는 치근파절의 증례의 경우는 제외되었다. 근관치료된 치아와 치료되지 않은 치아, 환자의 나이와 성별, 치아종류 및 파절된 치근부위, 자각증상의 유무를 기준으로 각각의 수치와 백분율로 분류하였다. 수직 치근파절의 증상과 증후별로 분류하였으며, 진단방법에 의한 분류, 치료방법에 따른 분류, 근관 치료 후 수직 치근파절이 발생한 기간에 따른 분류를 시행하고 통계분석을 하여 다음과 같은 결과를 얻었다. 1. 근관치료를 받지 않았던 치아의 수직 치근파절의 발생율은 58%였다. 2. 성별에 따른 발생률에 있어서 남성의 호발양상을 나타내었다. 3. 근관치료된 치아에 있어서 치료되지 않은 치아에 비해 호발연령이 낮았다. 4. 전치부의 수직 치근파절은 관찰되지 않았으며 특히, 강한 교합력을 필요로 히는 구치부에서의 높은 발생율을 나타냈다. 5. 수직 치근파절의 가장 주된 증상 및 증후는 깊은 치주낭 깊이였다. 6. 근관 치료 후 수직 치근파절이 발생한 기간은 평균 5.7년이었다. 7. 다수 증례에 있어서 3개 이하의 결손치를 가졌고, 자각증상이 나타났다. 이상의 결괴에서 한국인에 있어서 근관치료를 받지 않은 치아의 수직 치근파절은 드문 현상이 아님을 알 수 있었고 남성과 구치부에 있어서의 높은 발생율을 알 수 있었다. 그 이유로는 강한 교합력, 딱딱한 음식의 저작습관, 치조골 흡수에 따른 낮은 저항성, 골 유연성의 저하 등으로 여겨진다. 그러나, 수직 치근파절은 아직까지 정확한 진단을 내리기는 여전히 어려운 상태이며, 이를 위한 다양한 진단방법 및 더 나은 연구가 필수적이라 하겠다. 그리고, 향후 보다 많은 증례에 대한 분석, 치주질환에 이환되지 않은 경우의 분석, 치료 후 생존 기간에 대한 고찰 등도 필요하리라 사료된다.

The aim of this study was to analyze the factors related to self-reported halitosis. This study performed a questionnaire survey, targeting at 450 adults who lived in Seoul and Gyeonggi area. Main results of this study were as followings. Relationships between socio-demographic characteristics and halitosis showed no significant difference. Relationships between subjective oral health and halitosis, the groups that were treated dental prosthesis, aware of periodontal disease and dry mouth symptoms reported more halitosis (p<0.05). The group that brushed teeth less than twice a day, did not brush teeth after having a snack, and had frequent sweet treat reported more halitosis (p<0.05). The group that more experienced limitation, discomfort, discomfort reported more halitosis (p<0.05). Based on the results derived as above, the self-reported halitosis was shown to be related to periodontal disease, dry mouth, oral hygiene care and quality of life. Therefore, it is considered that preventing periodontal disease and oral dryness as well as reinforcing the oral hygiene care will contribute to prevention of halitosis and enhancement of quality of life.

Plant extract has attracted considerable interest in oral disease therapy. The present study was performed to observe the antibacterial effect on cariogenic Streptococcus mutans GS5 and Streptococcus sobrinus 6715, and periodontopathic Actinobacillus actinomycetemcomitans Y4 of phytoncide from Chamaecyparis obtusa Sieb. et Zucc employing the measurement of optical density, viable cell counts, and antibiotic sensitivity. The results were as follows: 1. Minimum inhibitory concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was observed to be 0.5%, 1%, and 0.2%, respectively. 2. Minimum bactericidal concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was determined to be 0.5%, 2%, and 0.2%, respectively. 3. The bacteria exposed to the phytoncide become more sensitive to antibiotics. The phytoncide enhanced significantly antibacterial activity of ampicillin against S. mutans and S. sobrinus. It also increased significantly the activity of penicillin and amoxicillin against S. sobrinus. In contrast, the phytoncide augmented the activity of amoxicillin and cefotaxime against A. actinomycetemcomitans but the increase was not statistically significant. The overall results indicate that phytoncide from Chamaecyparis obtusa Sieb. et Zucc used for this study has a strong antibacterial activity against cariogenic and periodontopathic bacteria and that it also has permeabilizing effect on certain antibiotics against these bacteria. Therefore, the phytoncide may be used as a candidate for prevention and therapeutic agent against oral infectious disease including dental caries and periodontal disease.
