It is widely believed that the increase in the prevalence of dental erosion is due to soft drinks. The purpose of this study was to assess the influence of soft drinks and etchant on the erosion of tooth enamel and the effect of tooth brushing on the abrasion of eroded enamel, and the effect of milk, saliva and Tooth $Mousse^{(R)}$ on the remineralization. The changes in tooth enamel surface were observed by scanning electron microscophy. The results were as follows; 1. The pH of Coca-Cola and Chilsung-Cider were higher than the pH of FineEtch 37 and $Tyrian^{TM}SPE$. 2. The SEM photos revealed that the pattern of the surface eroded by Coca-Cola and Chilsung-Cider were more obvious than that eroded by etchants. 3. The results of remineralization by saliva, milk, Tooth $Mousse^{(R)}$ were not different from each other. 4. The remineralization by saliva decreased tooth brushing abrasion.

Fifteen herbs used in oral medicine were extracted in ethanol and screened for tooth whitening effect, radical scavenging activity, inhibition of inducible nitric oxide synthase activity and anti-bacterial activity on Streptoccocus mutans. The results are as followed: 1. The tooth whitening effect of toothpaste containing 1 $\%$ ethanol extracts of 15 herbs was tested in brushing method using artificially stained HAT tablet and bovine tooth specimens. Toothpaste containing 1$\%$ of Vucia unijuga, Illicium verum, Angelica dahurica and Piper longum extracts showed tooth whitening effects on both HAT tablet and bovine tooth specimens. But the others did not show a considerable activity. 2. The antioxidant activity of ethanol extracts of 15 herbs was tested using the method of 1,1-diphenyl-2-picryl hydrazyl (DPPH) reactivity. Two ethanol extracts of Cimicifuga heracleifolia and Phyllostachys nigra var. henonis were found to be the most effective on radical scavenging activity. C. heracleifolia and P. nigra var. henonis extracts removed 86$\%$ and 81 $\%$ of DPPH radical at 0.01$\%$, compared with butylated hydroxy toluene as positive control. 3. The inhibition activity of ethanol extracts on nitrate production In RAW264.7 cell stimulated by lipopolysacchride was tested using the Griess reagent. But all extracts did not inhibit nitrate production. 4. The antibacterial activity on Streptoccocus mutans was tested by paper disk method. But no one extract showed any anti - bacterial activity.

Human teeth vary widely in color. Practitioner and patients are concerned with preventing and correcting discolored or dark teeth to achieve and maintain stain-free, white teeth. Tooth brushing cannot alter tooth color but it can remove adhering films and stains. The esthetics of natural dentition can be improved by bleaching and this process can be applied to intrinsically and extrinsically stained teeth. The need for a brighter, more attractive smile has made rapid growth in the market for tooth whiteners. There is no doubt these products work as whiteners, at least on mild to moderate stains, but the safety of these products are unclear. In this experiment, the effect of tooth whitener application on the color and microhardness of extracted human enamel was measured. RMS, RMT and NWT were used as tooth whiteners, and tooth paste(ETQ) and hydrogen peroxide solution(HPO) were used as controls. 35 caries-free extracted human molars were embedded and polished with the exposed enamel diameter of 4 mm. The tooth whiteners and control agents were applied according to the manufacturers' instructions or clinically simulated procedures for eight weeks, and measurements were repeated every two weeks. Value(L＊) difference was measured using Differential Colorimeter(Model TC-6FX, Denshoku Co., Japan), and microhardness was measured using microhardness tester(Mitsuzawa Seiki Co., Japan). The results were as follows; 1. After application of agents for eight weeks, the Vickers hardness increased significantly in the ETQ, RMS and RMT application group(p〈0.01), and that decreased significantly in NWT application group(p〈0.01), but in HPO application group there was no significant change. The change in microhardness was greatest in NWT application group(p〈0.01). 2. After application of tooth whiteners and controls for eight weeks, the value change of toothpaste application group was significantly lower than those of other agents groups(p〈0.01), and there was no significant difference in value(L＊) change among tooth whitener groups(p〉0.01). 3. The application of tooth paste and paste type tooth whitener made gradual value change, but hydrogen peroxide gel type tooth whitener and hydrogen peroxide solution made rapid value change during initial application period.

Objectives: The purpose of this study was to assess the effect of mothers education attainment on prevalence of dental caries among their preschool children. Methods: Data were obtained from the third 2006 Korea National Oral Health Survey. A total of 515 preschool children aged 2 to 7 years and their mothers were selected in this study. We used mother's education level as her socioeconomic position and controlled children's tooth brushing frequency, tooth brushing before bed, the frequency of eating snack, and the preventive dental visit. Whether children experienced dental caries or not and the number of decayed or filled or missing tooth surface they had were used as outcome variables. Results: The proportion of children affected with dental caries was 46.21%. The mother's education level affected children's caries significantly (p<0.05) and children whose mother attended less than high school had more possibility of having caries than children whose mother graduated from college or more (p<0.05). This effect was still significant and got larger(p<0.05), even after controlling children's dental health behavior. Conclusion: This study showed that mother's education level affected the prevalence of caries among their preschool children. In addition, this result indicated a need for more definite policy for children's dental health in lower socioeconomic class with general dental education.

To maintain and improve seafarers oral health, I investigated and analyzed the oral health status of seafarers: who are safety training at Korea Institute of Maritime and Fisheries Technology located in Busan. The results of the investigation and analysis are as follows: Two times of brushing teeth a day occupied $51.0\%$ the largest percentage, mixed brushing method was the highest as $39.0\%$, $64.2\% of respondents have recieved teeth scaling. Two or three of times snack intake per day occupied $62.6\%$ the largest percentage. Based on the objects' answer on oral status, the persons answered that my oral status is 'good' $25.9\%$ 'bad' $38.3\%$ occupied The persons with a decayed tooth occupied $78.1\%$ and as for the subjective symptoms of oral disease, $25.6\%$ of respondents answered that I felt sensitivity. Intraoral discomfortable symptoms in the respect of each age, under forty age had dental decay, over forty age had sensitivity of teeth. The more has a intake snack, the more has an oral disease and oral decayed tooth. As a whole of the above results in order to control oral health of the seafarers reasonably, time and economic limiting factors must be solved in the first. In planning oral health education, practicability should be emphasized especially.
