Dental caries is a multifactorial disease influenced by interactions between teeth, biofilm, dietary factors, and various biological, behavioral, sociocultural, and genetic factors. Recent research has shown that dental caries results from dysbiosis, an imbalance in the oral microbial community, shifting the concept from an infectious disease to a non-communicable disease (NCD). Dental caries shares similarities with other chronic NCDs such as cardiovascular diseases and diabetes, as they all relate to dietary intake, lifestyle habits, and environmental factors. Considering the high prevalence of dental caries and its impact on people's health and quality of life, it is important to understand dental caries as an NCD and develop effective oral health management strategies. Ecological prevention methods and efficient public health policies should be provided to reduce risk factors associated with dental caries.

The purpose of this study was to explore some of the right directions for school dental-health education, by examining nursing students' knowledge on and attitude to the two major oral diseases in our country, dental caries and periodontal disease, as they will take charge of dental-health education and care for children in school dental-health center as sole expert health personnels after graduation. As a result of making an analysis of their knowledge and attitude, the following findings were acquired: (1) The students investigated perceived their oral cavity to tend to be healthy(36.8%) or in moderate situation(36.3%), although they had a subjective symptom for hot or cold food. (2) They thought dental caries is attributed to poor dental hygiene care(90.4%). Among them, 94.1% found toothbrushing effective for the prevention of dental caries, but just 40.2% agreed that toothbrush should be straight. (3) Those who considered fluoride effective for dental caries prevention thought the best way to use fluoride is taking fluoride-containing tap water(2.00). The second best way was fluoride mouth rinse(2.40), followed by the topical application of fluoride(2.70), use of fluoride dentifrice, and intake of fluoride(4.30) in the order named. (4) The regular examination and toothbrushing were mentioned as a way to prevent dental caries, but just toothbrushing was put in action for dental health. So their knowledge and actual attitude weren't the same. (5) They brushed their teeth for oral health(94.3%). Toothbrushing was done after breakfast(71.9%) or before bedtime(65.8%). Just 40.3% performed toothbrushing after lunch. That was implemented twice(35.7%) or three times(37.6%) a day. (6) Out of those who pointed out toothbrushing as a way to prevent periodontal diseases(84.7%), the effect of toothbrushing on the prevention of periodontitis wasn't supported by 7.1% of those who completed the course of study for the teaching profession and by 17.0% of the others who didn't. The two groups weren't of the same opinion. The above-mentioned findings suggest that the dental knowledge of the nursing students wasn't good enough to be properly responsible for school children's dental health care. In particular, there was a gap between knowledge and attitude. To improve children's poor dental health and help their oral cavity stay healthy, there is a need to activate school dental-health center, which is now in model operation, and to make the most of dental hygienists, who are educated to be a dental-health specialist, for more successful dental-health care for school children.

The aim of this study was to evaluate QLF (quantitative light-induced fluorescence) technology for the caries detection in primary teeth and validate the relationships between the cavity volume of carious lesions and QLF analysis results. Total 125 tooth surfaces include 53 occlusal surfaces, and 72 proximal surfaces were investigated with the portable QLF device for detection of dental caries in primary molars. Micro-CT radiograph was also performed to classify carious lesions and calculate the cavity volume. QLF showed good accuracy and reliability (sensitivity 0.75 - 0.94, specificity 0.82 - 0.95, and AUROC 0.88 - 0.98) for the caries detection in primary teeth except 𝚫R average results of proximal caries which showed relatively low values. Statistically significant relationships were found between 𝚫F average, QS-Index and the cavity volume according to Spearman rank-order correlation coefficients (r = 0.805 - 0.832, p < 0.001). QLF detection method would be a harmless and reliable way for children to diagnose dental caries without the concern about radiation exposure.

Objective : This study came to be carried out in order to develop oral health education program for maintaining adolescents' oral health and to be helpful for qualitative improvement in prevention program by surveying the awareness and behavior on preventive method of dental caries in adolescents. Method : The collected materials of totally 1,100 people who responded were carried out frequency analysis by using SPSS 12.0(Statistical Package for the Social Science). Results : 1. As for the results of awareness on fluoride effect and sealant effect, the students with response to 'effect of preventing decayed tooth' were indicated to be the highest. It was indicated to be the highest in girls as for gender and in the 2nd grade as for school year. (p<0.05). 2. As for the results of being created when eating sweet food and carbonated drink, the students with response as saying that 'a decayed tooth occurs well' were indicated to be the highest. 4. As for the results on the aim of visiting dental clinic, the students with response as saying of 'visiting for having treatment' when tooth is painful were indicated to be the highest. Conclusion : Synthesizing this study, the students' awareness on preventive method of dental caries was high. But the practice on regular check-up or diet was indicated to be low. Through oral health education, the adolescents should be not only delivered information or knowledge, but also changed habit and behavior.

Mutans streptococci is the major causative factor in dental caries. Especially, orthodontic patients with fixed appliance are a risk group for dental caries. Because fixed appliances attached on teeth may change the environment of dental plaque, the enamel decalcification or dental caries around the bracket and band is a major side effect of orthodontic treatmet. The aim of this study was to search plant extracts that have antimicrobial effect on mutans streptococci. Seed-extract of Casia torn were prepared with ethanol and CHMC-2032, the leaf-extracts from Camellia sinensis extract, was obtained extract, 2 type strains and 20 clinical isolates of mutans streptococci isolated from the interface between orthodontic brackets and tooth surfaces in the orthodontic patients were used in this study. The minimal inhibitory concentration of CHMC-2032 was 5mg/ml on the S. mutans KCTC 3065, S. sobrinus KCTC 3088, and 8 clinical isolates of S. sobrinus. However, there was no antibacterial effect of seed-extract of C. tora on mutans streptococci. These data suggest that green tea nay be more effective than the tea Prepared from C tora In the prevention of enamel decalcification or dental caries around brackets.

This study is a review of research articles on the characteristics of probiotics. Probiotics are effective at ameliorating immune disease, alleviating glucose intolerance, and improving constipation and diarrhea. Furthermore, they have anticancer and antitumor effects, preventive effects against cardiovascular disease, antidiabetic effects, antioxidant effects, antibacterial effects, and they produce useful metabolites. It has been demonstrated that oral probiotics are effective in eliminating halitosis and forming a favorable oral ecosystem, by creating an environment that is not readily inhabited by harmful bacteria, such as Streptococcus mutans, which produces lactic acid and causes tooth decay, or Porphyromonas gingivalis, which causes gum disease.As a result, oral probiotics are being considered not only as therapeutics against diseases, but also as preventive agents for the maintenance of a healthy oral balance. In spite of some limitations, clinical trials are currently underway, and this study can provide evidence to support the use of probiotics to improve oral health conditions, including dental caries, periodontal disease, and Candida colonization.

The purpose of this study was to analyze college students basic knowledge of oral health of a college student and compare with the knowledge of oral health between dental hygiene students and non-dental hygiene students. A survey was conducted on the residents in Gyeonggi-do and Gwangju from June 2006 to May 2007. The findings of the study were as follows: 1. Concerning the knowledge of oral health, dental hygiene students got the source of information most frequently from school work about oral health(80.0%) and non-dental hygiene students got from health programs of TV or radio(42.7%). Concerning the reason of keeping of oral hygiene, dental hygiene students were to preventive of dental caries(80.9%) and nondental hygiene students were to preventive of periodontal disease(52.4%). There were significant difference between dental hygiene students and non-dental hygiene students(p < 0.001). 2. The knowledge degree of dental caries, to the both groups, methods of preventing caries appeared regular brush and main cause of dental caries was not to brush. There were significant difference between dental hygiene students and non-dental hygiene students(p < 0.001). 3. Dental hygiene students answered about the knowledge of fluoride know fluoride(93.6%) and non-dental hygiene students answered (55.3%). Dental hygiene students thought that fluoride could preventive dental caries(85.5%) but non-dental hygiene students thought that fluoride couldn't preventive dental caries(51.0%). There was significant difference between dental hygiene students and non-dental hygiene students(p < 0.001). 4. In the knowledge of oral health state, both of groups, replied that their own tooth state is average but they concerned about their tooth health. There was significant difference between dental hygiene students and non-dental hygiene students(p < 0.001). About main cause of dental caries, students ranked that the first reason was the poor toothbrush and the second reason was the over intaking of sugared foods. 5. About knowledge of oral diagnosis, to both groups, students ranked that first could endure the pain and the second was in much pain. For both groups, students ranked that difficult of dental treatment was cost, fear and time. There was significant difference between dental hygiene students and non-dental hygiene students(p < 0.01). For both groups, when they visit dentist's office, they felt misgivings and fear.
