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.

The reports concerning dental disease in handicapped children are contentious, and there are many differences of opinion as to what extent handicapped children differ in oral health and disease from healthy children. The present study was done by conducting a comprehensive study and evaluation of the oral health between the 267 handicapped and the 128 normal persons with regard to caries rate, occlusion and the condition of the periodontium. The result showed that the dft, the dfs and DMFT indices of handicapped persons according to age were significantly lower than those of normal persons(p<0.05). The prevalence of gingivitis in handicapped persons increased with age and was significantly higher than those reported for normal persons(p<0.001). It was found that the handicapped group had a significant difference in the class distribution of occlusion, with a higher percentage of Class II and Class III occlusion from that observed in the control group(p<0.05).

The aim of this study was to suggest a convenient method of monitoring the gingival state through plaque detection. Quantitative Light-Induced Fluorescence-Digital (QLF-D), which can assess mature plaque, can be used to assess the oral hygiene status of individuals and to establish an adequate intervention plans for them. The subjects of the study participated in the clinical training at Department of Dental Hygiene, N University. The subjects completed questionnaires on general characteristics and oral hygiene methods. Then, photographs of maxillary and mandibular anterior teeth of the subjects were taken using the QLF-D. After the oral examinations, gingival state was recorded according to the $L{\ddot{o}}e$ & Silness's Gingival Index (GI). In addition, a plaque control record was calculated in percentage using disclosing agent. The analysis of the relation between the plaque control record and the QLF-D scores showed positive correlation (r=0.638, p<0.001), and the analysis of the relation between the QLF-D scores and the gingival bleeding index scores also showed positive correlation (r=0.562, p<0.001). Besides, the study classified the participants into healthy gingiva group and the gingivitis group according to the classification criteria of GI, and when the difference of QLF-D scores between the groups was analyzed, the QLF-D scores were statistically significantly higher (t=-2.785, p=0.007) in the gingivitis group ($1.71{\pm}1.545$) than the healthy gingiva group ($0.74{\pm}1.290$). When the differences in mean values of the QLF-D scores were analyzed against and the gingival bleeding index scores, the QLF-D scores of 0 and 1 belonged to the category of normal gingival state while the QLF-D scores of 2, 3 and 4 belonged to the category of gingivitis state. Therefore, it is deemed that the red fluorescence detected by the QLF-D from the mature supragingival plaque can be used for monitoring the state of gingivitis.

Objectives: The purpose of the study is to investigate the effect of oral health education for the elderly using $Qscan^{TM}$. Methods: This study was a quasi-experiment design of nonequivalent control group pretest-posttest design carried out by oral health education from January 17 to March 7, 2015. The subjects were 64 elderly people over 65 years old who had more than one remaining teeth in the anterior teeth and canines living in Hongseong-gun and assigned to 33 control group and 31 intervention group. The intervention group was measured only by $Qscan^{TM}$. The educational effect between two groups were evaluated using oral health behavior, gingivitis index, and plaque index. After Institutional Review Board from Namseoul N University, the elderly people participated in the study. Results: The intervention group showed lower plaque index of percent reduction than the control group. The two groups showed a significant difference in gingival index after the oral health education(p<0.05), but did not show a significant difference in oral health behavior after the oral health education(p<0.05). Conclusions: The effect of oral health education through the motivation of $Qscan^{TM}$ was very effective in the comparison of oral health behavior, gingival index and plaque index.

Objectives: The purpose of this study was to investigate the influential factors of stress and fatigue on peridontal indicators in patients with periodontal disease. Methods: A self-administrated questionnaire study was conducted during November 2012 to January 2013 with 140 periodontal patients. The Fatigue and Stress were evaluated with Multidimensional Fatigue Scale(MFS) and Psychosocial Well-bing Index(PWI). Periodontal health indicators were consisted with gingival index and pocket depth. Data were analyzed by descriptive analysis, t-test, ANOVA, and multiple regression analysis. Results: Overall stress and fatigue level of subjects were $22.61{\pm}5.62$ and $64.67{\pm}9.45$. Gingival index and periodontal pocket depth as periodontal health indicators were $1.26{\pm}0.3$ and $4.29{\pm}0.52$. The influential factors of gingival index and periodontal pocket depth were social function(subcategory of pwi) and depression(subcategory of pwi), respectively. Conclusions: Some subcategories of PWI were related with periodontal health indicators. So, consideration of stress related with depression and social function are needed to manage and prevent periodontal disease.

It is widely known that individuals with Down's syndrome(DS) often develop early onset severe periodontal diseases. In this study, We examined the prevalence of periodontopathic bacteria in DS patients to compare controls with mental disabilities(MD) The subjects were 27 DS patients (7 to 19 years old) and 27 age-matched controls with MD. Plaque index and gingival index were measured. And 5 pathogens, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, were surveyed in subgingival plaque samples using a polymerase chain reaction. No significant difference in plaque index and gingival index were observed between the DS and control group. The prevalence in DS was 96.3% for F. nucleatum, 74.1% for T. forsythia, 63.0% for P. gingivalis, 55.6% for A. actinomycetemcomitans. 40.7% for T. denticola. No significant differences were observed in the prevalence of periodontopathic bacterias between the DS and control. Prevalence of P.g(16.7%) at age $7{\sim}10$ is lower than other age group in DS, but its prevalence increased with age. Prevalence of A.a(83.3%) is peak at age $7{\sim}10$ in DS. These results suggest that various periodontopathic pathogens can colo nize in the very early childhood of DS and MD patients. But no significant difference was observed in the prevalence of periodontopathic bacterias between the DS and control.

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.
