This study was investigated in order to provide basic data for prevention of periodontal disease and maintenance through proper lifestyle by finding the relevance of periodontal health with lifestyle habits. Data were collected from total of 326 subjects in their forties and fifties by using questionnaire and examination of periodontal health status. Results were analyzed by using IBM SPSS Statistics 19.0. The smoking status were statistically significant to gingival index (p<0.01), pocket depth (p<0.001), and clinical attachment loss (p<0.001). Smoking amount per day were statistically significant to gingival index (p<0.05), pocket depth (p<0.01), and clinical attachment loss (p<0.001). Duration of smoking were statistically significant to gingival index (p<0.05), pocket depth (p<0.01), and clinical attachment loss (p<0.001). Drinking cycle were statistically significant to gingival index (p<0.05), and clinical attachment loss (p<0.05). It is investigated that smoking (p<0.05) influence on clinical attachment loss. Dental care institute needs to make patients be aware of the fact that excessive smoking and drinking affect the periodontal health status for prevention of periodontal disease and maintenance of oral health. Therefore systematic educational programs to stop smoking and drinking should be prepared.

The purpose of this study was determine the effects of professional tooth cleaning and plaque control instruction(PT & PCI) on reduction of peri-implantitis. A total 80 implant patients were investigated using O'Leary plague index(PI), L${\ddot{o}}$e & Silness gingival index(GI), implant bone loss(BL). While the PT & PCI was conducted by using 'Watanabe method' after scaling for the experimental group, the engine polishing and a plaque control instruction was operated by rolling method after scaling for the control group. The collected data were analyzed with t-test, ANOVA, paired t-test and stepwise multiple regression. PI and GI of the experimental group significantly decreased than the control group(p<0.05). BL, also tended to decreased in the experimental group than the control group(p=0.155). Multiple regression analysis, the factors that was highly correlated with PT & PCI on the PI and GI. According to the implant characteristics, implant location and duration were closely related to PI(p<0.05). Therefore, the PT & PCI is one of the effective methods to reduce the failure caused by the peri-implantitis. Based on this conclusion, that it would be meaningful if the proposed PT & PCI is applied to the oral health management programs of the implant patients.

The purpose of this study was to investigate effect of the economic stress and state-trait anxiety on the periodontal disease in order to prevent the occurrence and progression of periodontal disease. Date were collected from total of 326 subjects in their forties and fifties by using questionnaire and examination of periodontal states during the period from February to November 2011. Results were analyzed by using frequency, t-test, ANOVA and Multiple regression of SPSS ver. 19.0. 1. The economic stress were significant statistically to the higher, medium and low of gingival index (p<0.01). 2. The state-trait anxiety were significant statistically to the higher, medium and low of gingival index (p<0.001), of the pocket depth (p<0.05), of the clinical attachment loss (p<0.05). 3. The gingival index were investigate effect of the higher the economic stress ($\beta$=0.052, p<0.01), the higher the state-trait anxiety ($\beta$=0.052, p<0.01). As a result, this study suggests that the dental clinic institute needs to let the patients with the periodontal disease know about the effects of economic stress and state-trait anxiety. They also necessarily need to implement education program including stress management, economic stress, and state-trait anxiety improvement in order to prevent periodontal disease and to take charge.

Objectives : This study mean to confirm the antibacterial activity of a garlic extract widely culturing in our region and was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and clinical studies in 50 healthy adults aged from 20 to 22 years who provided a consent for their participation. Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

In children, during developing occlusion stage, many studies confirm a high prevalence of gingival inflammation. Prevention, early diagnosis and treatment of gingival and periodontal disease is important because by establishing excellent oral hygiene habits in children, the risk of periodontal disease can be on the decrease in adulthood. This study evaluated the gingival conditions of 50 children$(8.5{\pm}3.1years)$ and 20 $adults(26.1{\pm}3.3 years)$ receiving clinical examination and GCF test at the pediatric dentistry of Chonbuk national university hospital in Jeonju, Korea. I estimated children's and adult's gingival states by measuring gingival crevicular fluid(GCF) using Periopaper and $Periotron^{(R)}$ 8000, gingival index, plaque index, DMFT scale. The results were as follows : 1. There are no statistical differences of GCF volume among the groups of the primary dentition, tooth erupting stage, complete eruption stage(p>0.1). But mean value of GCF is highest at the tooth erupting stage. 2. Comparing with adults, children have higher mean value of GCF volume with statistical differences (p<0.001). 3. There is statistically positive relationship between volume of GCF and gingival index (GI), plaque index(PLI) in both adults and children(GI; r=0.394, PLI ; r= 0.642). 4. There is no relationship between GCF volume and dental caries, composite resin treatments (p>0.05). But There is statistically positive relationship between GCF and orthodontic treatments(p<0.001) 5. Primary dentition has higher mean value of DMFT than permanent dentition(p<0.001). But there is no statistical relationship between GCF and DMFT (p>0.1).

The purpose of this study is to evaluate oral health status, caries-inducing bacterial activity of the mental retardation students, and developing motivation method for improving oral hygiene management by clarifying the relationship between caries-inducing bacterial activity and oral health status of mental retardation students. Caries experience indices, caries susceptibility test, gingival health evaluation, and oral hygiene management and oral health survey were performed. Results were as follows : 1. The DMFT index of disabled students(12 years) was 2.07. 2. The gingival inflammation was occurred more frequently in older ages. 3. There also was a high positive correlation between caries incidences and the results of caries-inducing bacterial activity test especially in deciduous teeth. This result suggested that the Dentocult SM mutans test as a caries activity test is a reliable method for measuring the status of dental caries in mental retardation students. Because it would motivate the mental retardation students to care more actively for their oral hygiene if they learn how much dental caries-inducing bacteria are living in their mouth by observing the bacterial colony on the cultured test strip, it can become a possibly efficient educational tool for the mental retardation students.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

This study was carried out in order to offer basic data available for being helpful to promoting periodontal health, by analyzing effects in socio-demographical and health-behavior characteristics on index of evaluating periodontal status. The study conducted a survey for the 151 adults aged 30 to 59 from October. 1, 2006 to March. 30, in 2007. The collected data were analyzed with t-test and one-way of variance using SPSS 12.0. Then, the following result were obtain. 1. sociodemographic and health-behavior characteristics is not related to O'Leary plaque index, Loe & Silness gingival index. 2. The number of sextants possessing periodontal pocket was higher in men(3.34) than women(2.43), also statistically significant difference in the occupational fields. Smoker(3.38) was higher than non-smoker(2.72), and it was higher over 3 times a week than almost no drinking as for frequence alcohol intake. 3. The amount of loss for inter-dental alveolar crest was higher in men(71.79) than women(42.24), was highest of the 'professional' in the occupational fields, and smoker(67.23) was higher than non-smoker(48.22). 4. There was significantly difference in the number of missing tooth between age and frequence of alcohol intake. These results that occupational fields, smoking and alcohol intake were related to the number of sextants possessing periodontal pocket and amount of loss for inter-dental alveolar crest.
