The purpose of study was to test the hypothesis that preschool children who experienced nursing caries have high dft index and caries activity in primary dentition. One thousand and seventy-five preschool children from 4 to 6 years old were examined for their caries experience and salivary invertase activity by Resazurin Disc Test. Nursing caries group was identified by the criteria of having more decayed and filled teeth among the upper incisors than among the upper molars. The prevalence of nursing caries was 15.8%. The dft index of nursing caries group was significantly higher than that of the other groups except the rampant caries group(P<0.01). The Resazurin Disc Test score of nursing caries group was significantly higher than that of the other groups(P<0.01) and there was no difference between nursing caries group and rampant caries group. Therefore, it is recommended that children who experienced nursing caries should be incorporated in the caries prevention program through the primary and mixed dentition.

The purpose of this study was to obtain the basic data provide continuous and active dental treatment for the mental handicapped children. The authors studied on the dental caries experience, oral hygiene slates and caries activity test in the mental handicapped children of 9-11 years old, who are housed by rehabilitation school in Kwang-ju and in the 30 normal children of 9-11 years old as a control group. Correlation coefficiency was calculated among the caries experience, oral hygiene states and caries activity test for every children. The obtained results are as follows. 1. The mental handicapped children showed remarkably high score compared to normal children in DMFT index(The Index score was $2.43{\pm}1.98$ in the normal children and $5.26{\pm}4.11$ in the mental handicapped.). 2. Correlation coefficiency was reveled very high score between DT index and DMFT index of the normal children(P<0.01), and the mental handicapped was also high score(P<0.01) between ft index and dmft index. 3. The PMA Index of the mental handicapped children was comparatively higher than the normal(The Index score was $4.03{\pm}4.44$ in the normal children and $7.87{\pm}7.33$ in the mental handicapped.). 4. In the correlation coefficiency between the caries experience and modified snyder test, DMFT index of the normal children was revealed some high score(P<0.05). DMFT index of the mental handicapped was showed remarkably high score(P<0.01).

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.

Objectives : The purpose of the study is to investigate the risk factors of dental caries in early childhood. Methods : Subjects were 197 mothers having 5 year old children. They completed the questionnaire from June 1 to July 14, 2012. Results : At birth, the age of mother and the number of teeth experiencing dental caries showed high correlation(r=0.163, p<0.05). Early beginning(r=-0.441, p<0.05) and long period(r=0.441, p<0.05) of mix feeding were closely related to dental caries outbreak. Long period of supplementary food caused deciduous dental caries (r=0.643, p<0.001) and dental caries experience (r=0.723, p<0.001). Long period of breast feeding (r=0.261, p<0.001) also caused deciduous dental caries. Low BMI of mother was colsely related to high dental caries(r=-0.206, p<0.01). Deciduous dental caries accounted for 61.8% and the number of teeth experiencing dental caries was 68.5%. Conclusions : Appropriate breast feeding habit is the most important behavior of preventing deciduous dental caries in 5 year old children.

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.
