The purpose of this investigation was to evaluate on the biodegradability, biocompatibility and tissue regenerative capacity of synthetic bioabsorbable membranes in beagle dogs. For animal study, 9 adult beagle dogs were used to examination, on the surgical implantation of membranes and histological analysis. In each animal, the 3rd and 4th premolars of the both sides of the mandible were selected as test teeth. Two types of bioresorbable membranes including "Guidor membrane", "S-membranes" were used to examining for biological activity, and also Gore-tex membranes was used for positive control. Surgically created defects were made in 2 premolars of both sides of the mandible at $3{\times}4mm^2$ in size and tested membranes were implanted in the defected area. A plaque control regimen was instituted with daily tooth brushing with a 0.1% chlorhexidine digluconate during experimental periods. All the experimental animals were sacrificed after 2, 4, and 8 weeks from surgery and undecalcified slides were prepared using the "sawing and grinding" technique described by Donath and Breuner". In biodegradability, all the membranes were started their biodegradation from two weeks after implantation and gradually demolished of their frame morphology from eight weeks. However, demolition of membranes in 8 weeks after implantation was highest in Guidor membranes and followed by S-membranes. Biocompatibilityof two kinds of biodegradable membranes including Guidor and S-mambrane were shown to be well tolerated to the surrounding tissue, and were minimal accumulation of inflammatory cell infiltration around the implanted membranes to compare with Gore-tex membrane. Regeneration of defected alveolar bone was initiated from two weeks of membrane implantation and new bone formation was gradually increased from that time. However, pattern of new bone formation on the defected areas of two kinds of biodegrable membranes was almost similar and quite competitive comparing with Gore-tex membrane. These results implicate that bioresorbable membranes should be highly useful tool for guided tissue regeneration of periodontal defects.

Objectives : The purpose of this study was to examine the influential factors for the oral-health practice of adult workers and the relationship of their health-promotion life style to the factors of oral-health practice in an attempt to determine the impact of health-promotion life style. Methods : The subjects in this study were 160 workers who worked in Seoul, North-Jeolla and South-Jeolla Province, and were at the age of 20 and up. The survey was conducted from February 1 to July 20, 2011. Results : As for the relationship of the general characteristics of the workers to the factors of their health-promotion practice, gender made statistically significant differences to toothbrushing female (3.24), and there were statistically significant differences in education/concern according to more than college(2.72) scored higher academic credential(p<0.05). The group of the workers whose health-promotion life style was better in terms of all the toothbrushing(3.35), use of oral hygiene supplies(2.19), regular dental-clinic visit(2.70), dietary control(2.84) and education/concern(3.20) scored higher, and there were statistically significant differences in the factors of education/concern(p<0.05). Their health-promotion life style had an impact on regular dental-clinic visit among the factors of oral-health practice(p<0.05), and there was a positive correlation between health-promotion life style and tooth brushing, dietary control(p<0.05), regular dental-clinic visit, education and concern(p<0.01) the factors of oral-health practice. Conclusions : Workers should be stimulated to get into sound life habits to change their behavior, and they should be urged to improve their preventive health care, to get a dental checkup and ultimately to promote their health as well. Companies should take measures to accelerate the oral health promotion of workers and provide more dental checkup programs for them to be more concerned about their oral health, to promote their oral health and to maintain the best oral health.

This paper analyzed health practices of students in an university in Chollabukdo Province. It attempted to study how many university students had what kinds of health practices. Furthermore, it tried to find out what are the major problems in health practice among university students. To study health practices of university students, this study sampled 1,469 students randomly. Many of the students had poor practices of teeth care. In tooth-brushing, many students (35.8%) brushed their teeth before breakfast in the morning. Most of the students (95% or more) visit dental clinic only when they had problem(s) in their teeth. For weights, there exists a great gap between perception and BMI (Body Mass Index), especially among female students. Among the female students who perceived their weights were above average, 96.4% of them were normal according to BMI. Many of the students were drinking greater amount of alcohol than safe amount suggested by the National Health and Medical Research Council of Australia. The proportion of the students drinking harmful or hazardous amount of alcohol were 79.5% of the male students and 74.9% of the female students. It suggests that health promotion fund or tax need to be levied on alcohol to frustrate unhealthful drinking. More than half (59.0%) of the male students and about 6.0% of the female students were smoking cigarettes. The smoking initiation ages were 17.8 for male and 18.2 for female students. It means that many of the students started smoking in their junior high or high schools. It implies that smoking prevention and smoking cessation programs need to be emphasized in these schools. For perception on sex, 27.8% of the male students and 60.9% of the female students thought to keep their virginity before their marriage. The female students were more conservative in perception on sex. The average number of sexual intercourses per year of male students was 17.0 times with their lovers, 7.9 times with prostitutes, and 7.0 times with maids. The female students had sexual intercourses 5.0 times with their lovers and 4.0 times with waiters per year. The proportion of students who had experience of sexual intercourse with homosexual partners was 1.0%. The finding this study was that the university students were vulnerable to poor health practices. It is suggested that public health intervention program be provided for university students to keep them in good healthy lifestyle.

Of the many first-occuring major manifestations of Behcet's disease, the oral ulcer is most frequently observed, shows the highest mean recurrence rate, and the longest mean duration period. A study of the relationship between mechanical irritation buy local factors and the recurrence of oral ulcers was carried out to see if there is a correlation. The subjects chosen for the study were 81 patients who were referred to the Department of Oral Diagnosis at Yonsei University Dental Hospital from the Behcet clinic of Severace Hospital after being diagnosed as Behcet's disease patients. 1. By Shimuzu's classification, possible type was the most numerous with 55.55% ; while suspected type was 19.76% ; incomplete type, 17,28% ; and complete type, 7.41% were observed in that order. The male to female ration was 1 to 1.61, and the average age of onset was 17.63 years. 2. Oral ulcers developed most frequently on the tongue (48.28%), and lip(23.15%), buccal mucosa (20.69%), palate\pharynx(4.43%), and gingiva(3.45%) also showed ulceration. 3. 38.27% of the patients were HSV positive : 27.16% were CRP positive ; 12.34% were ASO positive ; 9.87% were RF positive ; and 3.7% were ANA positive. 4. According to the answers to the survey, fatigue(85.18%) was most frequently associated with Behcet's diseage. Trauma by tooth brushing (22.22%), un specified reasons (20.98%), hard food chewing (12.35%), and irritation by dentition and/or prosthesis (13.58%) were observed in association with Behcet's disease. 23.46% had a history of tonsilitis. 5. Oral ulcers on the anterior part of tongue and buccal mucosa were associated with local irritatants. 6. Oral ulcers on the lip and posterior portion of tongue were not associated with local irritants. Local irritation by dentition and oral ulcer on the anterior part of tongue and buccal mucosa was observed to coexit with one another : in other words, lo9cal factors can act to cause of recurrence of an oral ulcer and to delay the healing process in Behcet's disease. Therefore, elimination of local factors along with systemic therapy must be recommended when treating oral ulcers.
