The purpose of this study was to evaluate the bioflavonoids naringin on dental caries and periondontal disease in the albinorat. Twenty-five-day-old-male rats were fed the experimental diets for 42 days in this work at the end of the 42-day experimental period. The tooth surfaces were examined under a dissecting microscope. The sulcular caries lesions were recorded : the first molars were more affected than the second and third molars. Alveolar bone loss was measured on the buccal and lingual aspects of each molar: three site measurements (mesialpoint midpoint and distalpoint) were taken on the first molars. The results showed that the bioflavonoids, naringin had beneficial effects in the prevention of periodontal disease.

임신기 구강관리와 영아의 구강관리에 대한 지식은 구강병을 예방하기 위하여 가장 기본이 되는 것이며, 구강관리는 습관화 되는 과정이라는 점을 감안할 때 이 시기의 관리가 무엇보다도 중요하다고 할 수 있다. 그러므로 연구자들은 임부들의 영아구강관리에 대한 지식을 살펴보고, 영유아기 우식증에 대한 인식정도를 파악하며, 임부들의 구강관리지식에 대한 잘못된 내용 포함정도를 살펴보기 위해 서울시 보건소와 유관업체에서 주관하는 임산부 건강교실에 참가한 임부 330명을 무작위 표본추출하여 개별면접방식으로 진행한 연구를 통해 다음과 같은 결론을 얻었다. 1. 임부들이 구강병을 중대한 문제로 생각하고 있는 비율은 82% 이었고, 잇솔질의 중요성을 인식하고 있는 비율은 94% 이었다. 2. 영유아기 우식증을 인지하고 있는 비율은 42% 이었고, 임신경험별로 통계적으로 유의한 차이가 인정되었다(p<0.05). 3. 영유아기 우식증 원인 중 잘못된 수유습관을 인지하고 있는 비율은 58% 이었고, 잘못된 모유습관에 의한 우식발생 가능성에 대한 인지율은 43% 이었으며, 임신경험별로 통계적으로 유의한 차이가 인정되었다(p<0.05). 4. 임신 중 태아는 모체의 치아로부터 칼슘을 빼앗아 간다고 인지하는 비율이 82% 이었다. 5. 임신 중 치과치료를 금하는 것이 안전하다고 인지하는 비율은 71% 이었다. 영아구강관리 및 임신기 구강관리에 대한 정확한 지식을 습득하고 있는 비율이 상대적으로 낮았고, 임신기 구강건강증진을 위한 프로그램의 개발과 정확한 구강관리 정보를 체계적으로 제공해 줄 수 있는 기회의 마련이 시급하다고 검토되었다.

It is noted that Streptococcus mutans (S. mutans) triggers dental caries establishment by two major factors: the synthesis of organic acids, which demineralize dental enamel, and the synthesis of glucans, which mediate the attachment of bacteria to the tooth surface. Therefore, it is noted that the development of a more effective, substantial and safe preventive agent that works against dental caries and periodontal disease is required at this time. For this reason, the present study was designed to investigate the effect of croton seed ethanol extracts on the growth, acid production, adhesion, and insoluble glucan synthesis of S. mutans. In this case, the ethanol extract of croton seed showed concentration dependent inhibitory activity against the growth, acid production and adhesion of S. mutans. Especially, it is important to note that it has produced significant inhibition at the concentration of 0.1 and 0.2 mg/ml as compared to the control group. Moreover, these results suggest that the application of croton seed extract may be considered to be a useful method for the prevention of dental caries.

Objectives: The aim of this study was to investigate the effect of water fluoridation program(WFP) on dental caries prevention in Ulsan, Korea. Methods: The data of control group were extracted from 2012 Korean National Oral Health Survey(KNOHS). Since 1998, WFP was implemented in Ulsan. The subjects were 670 subjects including 10 to 12-years old children in 2009. The control subjects were 4,871 people in non-fluoridated metropolitan cities comparable to Ulsan. The control subjects were selected from 2012 KNOHS. A self-reported questionnaire was completed by the variables including oral health behaviors on daily frequency of toothbrushing, eating snacks and beverages. Oral health examination was carried out by two dentists who received a training in KNOHS with an inter-examiner-agreement. Caries preventive fraction was calculated by the difference of DMFT and DMFS index. The preventive effects of the WFP program were focused on gender, number of fissure sealed teeth, daily frequency of toothbrushing, eating snacks and beverages. Data were analyzed using SPSS $19.0^{(R)}$(SPSS Inc., Chicago, IL, USA) statistical package. Results: DMFT indices of 12-year-old subjects(n=670) in WFP and control population(n=4,871) were 2.11 and 1.23, respectively with an estimated prevention effect of 41.7%. Conclusions: WFP in Ulsan reduced the prevalence of dental caries. WFP should be recommended for the public oral health program in other metropolitan cities.

The purpose of this study was to investigate the knowledge and attitude of a group of mothers who had infants about baby bottle tooth decay(BBTD) and dental caries prevention. The sample consisted of 261 mothers who had infants from 6 to 36 months from certain areas of Dae-jeon city. The mothers were asked to answer a questionnaire which included a series of questions regarding general information cencerning the infant and his mother, knowledge about BBTD and methods of prevention using fluoride, knowledge about behavioral risk factors contributing to caries of the infant, attitude toward oral health care of the infant, opinions regarding the effectiveness of methods to prevent dental caries and sources of oral health information. he results of this study were as follow. 1. 85.4% of the respondents thought that prolonged bottle feeding would harm the teeth of the infant, but 77% of the respondents had never heard of baby bottle tooth decay. 2. Levels of knowledge about methods of prevention using fluoride were relatively low and there were significant relationships between the levels of this knowledge and the educational level of the respondents(P<0.05). 3. Only 7.3% of the respondents thought that prolonged breast feeding would harm the teeth of the infant. 4. Overall oral health care of the infants was relatively insufficient. 5. Only 28.7% of the respondents selected either when the first tooth erupt or deciduous dentition complete as the time a infant should first be seen by a dentist. 6. 64.6% of the respondents thought that toothbrushing should be instituted once the first tooth appears. 7. Among the six methods of preventing caries in infants, respondents ranked the effective of fluoride lower than making regular dental visits and reducing intake of sugared foods. 8. Most frequently cited sources of information about dental health were newspapers, magazines and books(65%), followed by friends, neighborhoods and families (55%).
