Objectives : The purpose of this study was to correlation between the index of dental caries in primary teeth and the habits of diet and snack which are expected to influence on the index. The subjects of this study were 165 parents of the children who visited a pediatric dental hospital located in Gyeong-gi do from Jun. 15th to Sep. 26th, 2009, and the self-report questionnaire survey was performed. Methods : A questionnaire used in a previous study was revised and completed for this study and it consisted of 15 items on general characteristic, nine items on dietary habit, and five items on snack intake habit. The collected data was analyzed using SPSS program and findings are as follows Results : 1. The index of dental caries in primary teeth by ages was that children of four years old has 4~5 with 27.5%, children of five years old has 2~3 and 4~5 with 33.3% and children of six years old has 1 and 8~9 with 25.6%, showing a statistically significant(${\chi}^2$=37.72, p<.01). 2. The frequency of brushing teeth was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=61.20, p<.001). 3. The frequency of taking snack was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=51.42, p<.001). 4. The desirability of dietary habit was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=36.51, p<.001). 5. The frequency of taking biscuit was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=67.74, p<.001). 6. The frequency of taking bread was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=29.63, p<.01). 7. The frequency of taking caramel and candy was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=38.85, p<.001). 8. The frequency of taking soft drinks was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=52.92, p<.001). 9. The frequency of taking ice-creams was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=75.07, p<.001). Conclusions : Those findings show that the children with undesirable dietary habit and higher frequency of taking snack have higher index of dental caries in primary teeth, therefore, it is considered that the regular brushing teeth and establishment of desirable dietary habit are very important for keeping health oral cavity. It is recommended that the continuous concern and repeated learning are needed in house and group of rearing infants so that the children take foods of fruits which have function of self-purification than the food of carbohydrates which has high adhesion and level of sweetness.

This study was implemented for 84 students of dental hygiene to show the correlation between dental caries experience and improved caries activity test. Dental caries experience for the sample groups was examined and stimulative saliva secreted for 5 minutes was collected into the tube to check saliva secretion rate. Dentocult LB test was executed to observe Lactobacilli colonies after 96 hour cultivation of culture slides moistened with stimulative saliva. Dentocult SM test(screening strip, site strip) was done to measure SM colonies distribution after 48 hour cultivation of culture strips applied with collected saliva and dental plaque respectively, and salivary buffering capacity was checked by means of Dentobuff strip kit. Following conclusions are obtained after examining the relation between Dentocult LB, Dentocult SM, Dentobuff strip test results and DMFT index, salivary secretion rate. 1. Showed no significant difference between Dentocult LB test results and DMFT index, salivary secretion rate. 2. Showed no significant difference between Dentocult SM(screening strip) test results and DMFT index, salivary secretion rate. 3. Showed significant difference between Dentocult SM(site strip) test results and DMFT index(pE0.05), but showed no significant difference between Dentocult SM(site strip) test results and salivary secretion rate. 4. Showed no significant difference between Dentobuff strip test results and DMFT index, but showed a very wide difference between Dentobuff strip test results and salivary secretion rate(pE0.01).

The purpose of this study was to know whether the information of caries activity and caries experience of the children can be used to predict the behavior of the children during the dental treatment. The subjects of the study were one hundred and eighty-one preschool children, three to six years old. Salivary reductase activity was tested by the Resazurin Disc Test. Caries experience was examined. The children's behavior was observed using the rating scale of Frankl. Salivary reductase activity of the negative behavior group was slightly higher than that of the positive behavior goup, but the difference was not significant. dt index and ds index of the negative behavior group were significantly higher than those of the positive behavior group. There were no significant differences in ft index and fs index between the two behavior groups. The results suggest that the negative behavior of a child can be predicted when the child has many untreated dental caries.

To study the caries patterns in primary dentition, 719 preschool children, 4-6 years old, were examined for their caries activity(salivary reductase activity) and caries experience of individual teeth. Teeth groups were made by cluster analysis using dft indexes of individual teeth as criteria. The six major teeth groups in the order of dft index from high to low were (1) lower primary molars, (2) upper primary molars, (3) upper central incisor, (4) upper lateral incisor, (5) canines, and (6) lower incisors. There were significant differences in dft index between teeth groups except upper lateral incisor and canines. Upper and lower primary molars showed the highest correlation in dft index, and the next couples were upper central incisors and upper lateral incisors, upper lateral incisor and canines, upper central incisor and canines, upper lateral incisor and upper primary molars, and canines and upper primary molars in descending order. Upper first primary molar showed the greatest differences in dft index between caries activity levels.

The purpose of this study was to investigate the relationship between the caries experience and anxiety level to the dentist in the preschool children. 511 preschool children were brought to the dental hospital and examined for caries experience. Caries experience was measured as dDT index, fFT index, dDfFT index, dDT rate, and fFT rate. Children were requested to draw a dentist. Drawings were analyzed by the method of Human Figure Drawing Anxiety Score. Pearson correlation coefficents and their significance were calculated between caries experience and anxiety scores. There were significant negative correlation between fFT index and anxiety scores, between dDfFT index and anxiety scores, and between fFT rate and anxiety scores. There was significant positive correlation between dDT rate and anxiety scores. The results seemed to suggest that dental treatment experience reduced children's anxiety toward dentists. But, because there was obvious negative correlation between age and anxiety scores, age factor should be considered in the interpretation of the results.

Objectives: This study aims to evaluate the association between intake of energy, calcium and protein and permanent teeth caries in Korean children. Methods: Research data were obtained from the Fifth Korean National Health and Nutrition Examination Survey (KNHANES) and 1,274 Korean children within 9 to 12 years were selected as subjects for the study. The DMFT index, nutrition factors including total energy and protein intake, and degree of calcium intake were identified Chi-square test was performed to assess the difference of distribution in socioeconomic status, oral health behavior and nutrition factors according to sex. Multilevel linear regression analysis was performed to identify the relationship between DMFT index and the related variables. Results: Significant differences in energy, protein and Ca intake were confirmed according to the sex. Among 10 year-old children who intake total energy less than the recommended had few dental caries (p=0.058, ${\beta}=-0.411$). In addition, 11-year-old children having protein intake more than the recommended experienced dental caries (p=0.02, ${\beta}=0.588$). Conclusions: These results suggest that, there is significant differences between intake of energy and protein and dental caries among Korean children. However, further researches is needed to confirm between intake of energy and protein as a related factor.
