This survey was performed as a pilot of comprehensive survey of 18-month old infants which is an important period in pediatric dentistry. Through the oral examination of 154 infants of 18-month age, labored at Pusan National University Hospital and Ilsin Christian Hospital, and direct interview with their first caregivers (mother in most cases), we investigated into the state of their weaning and feeding, between-meal snacks, oral hygiene care, tooth eruption and dental caries and obtained the results as follows : 1. 73% of the infants had not yet weaned, and 82% of which were being milked during or before sleep without oral hygine care. 2. Snacks were taken in order of fruits, biscuits, cheese, bread and candies, and beverages in order of water, fermented milks, milk, sugared juice, fresh fruit juice. 61% of the infants ate snacks irregularly. 3. The toothbrush for infants was the most popular way of oral hygiene care. The mean age of initiation of tooth brushing was 13.8 months and the mean frequency was 1.6 times a day. 4. The incisors in all infants, the 1st molars in 86%, and canines in 66% were erupted. The average number of erupted teeth was 14.1. 5. The caries prevalence rate was 27.3% and 73% of total caries was observed in maxillary deciduous incisors. dmft index was 0.97. Through these results, it was concluded that a systematic education about weaning time, mode of snacking and the way of oral hygine care is required for the parents.

The time 18 months after birth is very important for the prevention of early childhood caries because this time is proper to assure the completion of weaning and to perform the diet counseling, and caries process is initiated or actively aggravated under the total influence of feeding pattern from this period. For the purpose of examining the infection status of Streptococcus mutans and Lactobacillus of 18 month old infants and their mothers, and analyzing the correlation between infection status versus various caries-risk factors, this study was performed on the 60 infants of 18 months old and their mothers through the microbiological screening of saliva samples and direct questionnaire to mothers about the caries risk factors. And the results were as follows, 1. The higher the mother's infection level of S. muntans, the higher the infant's infection level and transmission rate. 2. Compared with non-caries group, higher infection level of S. mutans in both infants and mothers and transmission rate were revealed in caries group. 3. The higher the infant's infection level of S. mutans, the higher the caries prevalence and deft values, the less the monthly income of the parents, the longer the period of breast feeding, and the higher the consumption rate of sugared snacks. 4. Most of Lactobacillus infected infants were revealed to be infected also with S. mutans and to have caries. 5. The higher deft value, less parents' monthly income, more frequent daily nursing and more irregular snacking patterns were found among Lactobacillus infected group compared with not-infected group.

For the purpose of investigating the etiologic factors of early childhood caries in 18-month old infants which is an important period in pediatric dentistry, 234 infants of 18-month age and their first care-givers (mothers in most cases) who visited Ilsin Christian Hospital in Busan for the baby-care counseling and vaccination were examined. The oral examination was performed on the infants and their care-givers were individually interviewed about various items, and the data was statistically processed to yield the results as follows : 1. The prevalence rate of early childhood caries was 27.4%. 2. The percentage of the eldest child, the education level of the mother and monthly income were revealed lower in caries group infants. 3. The percentage of prolonged breast-feeding and the frequency of daily nursing was higher in early childhood caries group. 4. In early childhood caries group, the between-meal snacks were tend to be provided irregularly without predetermined time, and sugar containing snacks such as chocolates and candies were ranked in higher order whereas the fruits and milks were in lower ranks. 5. In early childhood caries group, the percentage of those performing the oral hygienic care was lower and the timing to start the toothbrushing was comparatively later. From the above results, it can be concluded that prolonged breast-feeding, poor snack habits and lower socioeconomic status act an important role in early childhood caries in 18-month old infants.

Objective: This study aimed to understand mothers' beliefs about infants and their practices. Methods: As a qualitative study, the participants were 11 mothers and their 18-24 month old infants. Data were collected through in-depth interviews and observations. Results: The participants' maternal beliefs about infants were contrasted in terms of infants' abilities and respect for infants. First, the mothers that perceived infants as competent beings, believed that infants can understand daily routine, communicate and empathize, and concentrate. On the contrary, the mothers that perceived infants as incapable beings, believed that infants lack the understanding of daily routine and the abilities of communication, empathy, and concentration. Second, the mothers that perceived infants as subjective beings, respected their infants, and their infants' opinions when making decisions. On the other hand, the mothers that perceived infants as objective beings, believed that infants should be led by adults and their opinions as not being very important. Third, their maternal beliefs were closely connected to their practices. Conclusion/Implications: Since maternal beliefs about infants turn out to be significant in mothers' thoughts and practices with their infants, it is necessary to figure out maternal beliefs about infants and support them to have more positive beliefs.

Purpose: To find out the differences in eating habits between poor feeding and non-poor feeding children. Methods: We performed questionnaires on 504 children under four years of age who visited hospitals in Gwangju city and JaollaNamdo from May to August, 2002. Results: 138 (27.4%) children were included in poor feeding group, and 366 (72.%) children were in non-poor feeding group. Breast feeding rate was 18.8% in the poor feeding group and 20.3% in the non-poor feeding group. Duration of breast feeding for less than six months were noted in 70.5% of poor feeding group, and 58.5% of non-poor feeding group. The time at starting solid food in the poor feeding group was as follows; 15.9% of infants started on solid food when they were 2~4 months old, 32.7% during 4~6 months, 38.1% during 6~8 months and 18.8% over one year of age. Solid food was given in wrongly manners in both groups by nursing bottles, including 80.4% in poor feeding group and 66.6% in non-poor feeding group. Conclusion: This study demonstrated close relationships among poor feeding children under four years of age with history of low rate and short duration of breast feeding, inappropriate time to start on solid food, less interest in food during mealtime, and unbalanced diet. Pediatricians should make an effort to play an important role in nutritional education and treatment in children.
