A fibrin adhesive have been widely used in oral and maxillofacial surgery for microvascular anastomosis, autogenous chip bone grafts, many kinds of soft tissue surgery (vestibuloplasty, bleeding control after extraction, primary healing by covering of suture of a gum after the extirpation of large cysts). There are two principal components in adhesive systems biologically: lyophilized human fibrinogen and bovine thrombin. The fibrinogen component contains coagulation factor XIII and enhance the initial wound healing, which polymerizes soluble fibrin monomers into an insoluble clot. The thrombin is dissolved in a solution of calcium chloride to provide the second component. We applied fibrin adhesive, Beriplast (Behring, Behringwerke AG, D-3350, Marburg, FRD), to 4 patients for fixation of free skin grafting donors who had facial scar around eye, nose, mouth corner which received from accidents, or burn. We have experienced initial accelerated graft fixation between donor and recipient sites with no additional fixation. And It's made easy bleeding control and easy manipulation during operation. But two cases showed partial hypertrophic scar engrowth in above 3 months follow up, but no significant. Histopathological reviews in general were showed similar scar findings such as abundant collagen bundles in H&E, M/T stain, but slight positive signs in elastic and collagen antibody immunopathologic findings in hypertrophic scar cases.

Grapefruit seed extract has been reported to have antimicrobial effect. The purpose of this study was to evaluate the antimicrobial and anti-gingivitis effect of chewing gum containing grapefruit seed extract and xylitol. 40 healthy subjects with gingivitis or early periodontitis were divided into two groups. Subjects in the experimental group chewed gum containing grapefruit seed extract and xylitol while subjects in the control group chewed gum containing only xylitol. All subjects received scaling and tooth brushing instruction. 1 week after scaling was set as baseline. Gingival index and plaque index were scored at baseline, 1 week, 2 week, 3 week and 4 week. Bleeding index, probing pocket depth and clinical attachment level were scored at baseline, 2 week and 4 week. The number of total bacteria and Streptococcus mutans in unstimulated saliva of experimental group were counted at 1 week, 2 week, 3 week and 4 week. Gingival indices of experimental group and control group at baseline, 1 week, 2 week, 3 week and 4 week were 0.850${\pm}$0.298, 0.575${\pm}$0.345, 0.533${\pm}$0.332, 0.459${\pm}$0.311, 0.408${\pm}$0.224 and 0.758${\pm}$0.379, 0.592${\pm}$0.276, 0.563${\pm}$0.281, 0.454${\pm}$0.194, 0.413${\pm}$0.199 (mean${\pm}$SD), respectively.

The purpose of this study was to investigate the effects of stress on oral health and health behaviors. The study was conducted on 72,060 people using 11th Youth Health Behavior Online Survey in 2015. The study shows that In general, female students, high school students and students with high performance ranking are more stressful than male students, middle school students and students with low performance ranking respectively. Studies have shown that students who do not exercise a lot and have not breakfast get relatively high stress. Plus, the stress index was also high and statistically significant. (p<0.001). The study also shows that students who have got symptoms of "tooth pain when eating" and "bleeding gun" at the questionnaire of "Self-assessed Oral health status"get high stress relatively. And the study tells us that students who have bad breath get high stress relatively as well. And, the stress index was also high and statistically significant. (p<0.001). The implications of this study are that psychological stress among adolescents has a close relationship with oral health and health behavior.

Objectives : The study examined the correlation the between smoking and the actual smoking condition, knowledge, attitude and practice on the dental health of korean soldiers. Methods: The data was collected from a questionnaire given to 301 soldiers at two separate units in Kangwon-DO. Results : Soldiers dependance on nicotine according to the smoking frequence showed positive correlation(p<0.001). The respondents who had bad breath and bleeding gum had smoked for a relative correlation with how long they had smoked. Among the content of the dental health care program that respondents wished to undergo, dental whitening was the most attractive topic(37.9%) and decayed teeth was the most important part in dental health care(25.2%). The correlation coefficient between the dependancy on nicotine the less effort they made to improve their dental health(p<.05). Conclusion : The study suggest that antismoking campaigns should be include in military dental health care programs. Furthermore, the development of dental health care programs considering the needs of each military unit is basic for practice on dental health care between Korean soldiers.

Objectives : The aim of the study is to offer basic data that help to reduce dental fear by measuring adult dental fear level with DFS scale. Methods : The subjects were 300 persons including college students in W University and their parents in Jeollabuk-do Province. Data were collected by convenience sampling from May 1 to May 30, 2013. Results : 1. Dental clinic visit provoked pain in 99 people(47.4%). Oral examination and preventive treatment evoked pain in 13 people(6.2%). 2. Women tended to feel much pain than men. Both women and men felt the thrilling fear when a needle pricks the flesh. 3. Respondents having dental caries, gum bleeding, halitosis, shaking tooth, and painful tooth had a higher dental fear level. 4. The direct pain experience(p<0.001) had the greatest influence. The next influencing factor was the insufficient anesthesia(p<0.05). 5. The explanatory power that the pain experience has influence upon dental fear is $R^2$=0.151. Conclusions : The direct pain experience and the insufficient anesthesia experience have the great influence upon patients' dental fear level. Anesthetics and analgesics can be considered as one of the positive methods for pain control.

Poly(ethylene terephthalate) (PET) fabrics were treated with a silica particle and phosphate flame retardant to determine the optimum process condition of the digital textile printing(DTP) media. The treating conditions for the study were 6 conditions, from F1 to F6, in which F3, F4 and F5 were treated with mixture of both silica particle and phosphate compound in process of pad, dry and cure fixation. F6 was treated with phosphate compound only and silica particle coating successively. Xanthan gum was used to control the migration of liquid phosphate compound onto PET fabrics. The change in surface morphology of fabrics treated with silica particle and phosphate compound was observed by SEM and flame retardance was evaluated by limiting oxygen index(LOI). It was observed that F6 was the excellent flame retardance and low bleeding in printing, Collectively, the printing characteristics of silica to cyan, magenta, yellow and black ink and flame retardance of fabrics finished with phosphate compound were identified in this study.

Objectives: The purpose of this study is to investigate the effect of depression and stress on subjective oral-related symptoms in adolescen. Methods: This study was based on the 17th Korea Youth Risk Behavior Survey(KYRBS, 2021). A total of 54,848 individuals who responded to items regarding to depression, stress, and subjective oral symptoms were analyzed. Logistic regression analysis was performed to examine subjective oral-related symptoms according to depression and stress, and the analysis results were presented as OR (odds ratio) and 95% CI (confidence interval). Results: Among the subjective oral-related symptoms, 'aching and throbbing teeth' was 1.41 times (95% CI: 1.34-1.49) higher in the group with depression, and 1.40 times (95% CI: 1.31-1.51) was significantly higher in the group with stress. In the case of 'gum pain or bleeding', the symptoms were significantly higher in the group with depression and stress by 1.36 times (95% CI: 1.27-1.45), respectively. Conclusions: As a result of this study, it was found that depression and stress in Korean adolescents had an effect on subjective oral symptoms. Study results suggest that depression and stress in Korean adolescents has an effect on their subjective oral-related symptoms
