It is important to practice preventive method to control oral disease. Dental caries tendency has been decreased in developed countries, but early childhood caries(ECC, BBTD) became serious dental problems in many countries. To slove these problems, more positive and definite prenatal programs on infants and child are needed. Mostly the control of oral health was affected by a mother's knowledge and behavior in this stage. According to many studies, prenatal education is the most effective method to promote oral health in children. But in Korea, there is little oral health education programs for pregnant women, nursing mothers, infants and children. The purpose of this study was to access the knowledge and opinions of caries prevention among gravid women. 330 pregnant women(primiparae=181, multiparae=149), aged 23 to 39 years were randomly selected at prenatal health education courses in Seoul, Korea, 2000. Face-to-Face interviews were conducted by a trained interviewer using questionnaires included demographics, attitude toward children's dental cares, knowledge of early childhood caries, knowledge concerning pregnancy and oral health. The obtained results were as follows; (1) Most respondents were very concerned about their children's oral health. (2) 58% of the respondents were unaware of early childhood caries and the proportion was significantly higher among primipara (p<0.05). (3) Only 43% of the respondents believed that improper breast feeding could develop ECC, the proportion was significantly higher among primipara(p<0.05). (4) 82% of the respondents reportedly believed that the fetus takes away calcium from the mother's teeth during pregnancy. (5) 71% of the respondents believed that dental treatment during pregnancy was unsafe. There is a relatively low level of accurate knowledge regarding infant nutritions, maternal need for oral health and dental caries prevention among pregnant women. Oral health education and promotion programs that are science-based are needed for gravid women.

The purpose of this study was to examine unmet dental care needs and related factors among adults in Korea. The study included a nationally representative sample of Koreans (Korea National Health and Nutrition Examination Survey 2104). The dependent variable was unmet dental care need and the independent variables were socioeconomic status and oral health status. The chi-square test and logistic regression analysis were performed to identify the associations between explanatory variables and unmet dental care needs. The major causes of unmet dental care needs included economic burden, work life, and academic reasons; in addition, dental treatment was considered to have lower priority. The factors that had statistically significant relationships with unmet dental care needs were sex, age, self-rated oral health status, and difficulty in mastication. The findings of the study, suggest a need for lower dental insurance copayments in keeping with the policies and principles aimed at strengthening the national health insurance system. In addition, groups with limited access to dental services should be identified, and effective health care policies and services should be established for these individuals.

This study was carried out to investigate and analyze the congnitive degree of dental subjects and general pubic who have an experience to be treated for their teeth on the dental knowledge, operative dentistry, and dental prothesis in the oral health care through the questionnaires. The results are as follows: 1. In the knowledge on the care of dental prothetic stuff, there isn't any significant difference, but the degree of therapeutic knowledge was significantly high as showing 71.6% in I can prevent a gingivits;(P<0.01) Therefore, they have well known an importance of prevention. 2. In the knowledge on the orthodontics, it was appeared to cure their teeth due to an esthetic reason(47.9%). There is not any significance in the Statisics, but it appeared the relatively high knowledge in the time and period of orthodontics(P<0.01) 3. In the congnition on the necessity of dental prothesis, it appeared relatively high, but 'Be necessary' didn't show the significance as 77.2%. The proferance to dental prothesis material showed the similar difference of porcelain(45.6%) and gold(43.7%), and the moderns tend to ptefer porcelain teeth similar to the color of matural teeth in the modern, getting out of the existing cognition of preferring the gold. Accordingly it is considered to be preferentialy necessary the motivae the general public for the oral thealth education on the dental knowledge, operative dentistry, and dental prothesis the knowledge and practice of general public have an important effect upon the oral health as the abovementioned results.

Sturge-Weber syndrome is a rare nonhereditary developmental condition that is characterized by a hamartomatous vascular proliferation involving the tissue of brain and face. The clinical features are characterized by port wine nevus following one or more divisions of trigeminal nerve, ocular involvement and neurologic involvement such as epilepsy, mental retardation, and contralateral hemiplegia. Oral manifestations include unilateral blood vessel expansion of the oral mucosa, vascular hyperplasia of gingiva, pyogenic granuloma-like massive hemangiomatous proliferation of oral mucosa, macrodontia, ipsilateral macroglossia, blood vessel anomaly of maxilla or mandible and abnormal tooth eruption sequence. This case report is about 11-year-old Sturge-Weber syndrome patient presented port wine nevus on the face, venous malformation on soft plate and buccal mucosa. In this case we performed simple extraction of several deciduous teeth and periodic oral hygiene management. If a patient with Sturge-Weber syndrome has to undergo dental surgery in affected areas of the mouth, great care must be taken to prevent severe hemorrhage.

In removable dental prostheses, it is important to minimize impairment of residual tissue caused by wearing dentures. There are two factors that harm residual tissue. The first is functional load bearing of remaining teeth and alveolar ridges and the second is the effect of poor oral hygiene. Double crown retained removable dental prostheses provide rigid support, and it may reduce impairment caused by load bearing of alveolar ridges. Also, dental plaque and oral deposits, which are attached to outer crowns and dentures, can be easily managed extra-orally. In addition, it is beneficial to the health of the marginal gingiva because inner crowns have easy access for oral hygiene. In this case, double crown retained removable dental prostheses were used for the partially edentulous patient with severe residual alveolar bone resorption and poor oral hygiene, and the result was clinically satisfactory in terms of functional, esthetical, and oral hygiene aspects.

부유 분진의 입경에 따른 물리, 화학적 특성은 대기질 및 인체의 건강 측면에서 중요한 변수로 작용되고 있으며, 호흡기내 침착 및 가시도의 영향에도 밀접한 관련이 있다. 거대입자는 주로 자연적 발생원에서 방출되고 호흡시 구강이나 코에서 대부분 제거된다. 미세입자는 인위적인 배출원에서 주로 방출되며 입경이 10$\mu\textrm{m}$이하인 것으로 보고되고 있다. 이들 1차 생성분진과는 달리 대기중에서 황산가스나 휘발성유기화합물 등이 응축과정을 거쳐 가스상에서 입자상으로 변환되어 생성된 입자도 환경학적으로 매우 중요한 의미를 갖는다.
