| Abstract |
|
The purpose of this study was to investigate the tooth surface caries patterns in the primary dentition according to breast or bottle feeding. The subjects of study were 815 children, 36 to 71 months old, in Iksan, Cheongju and Ulsan cities. The caregivers of the children were asked which they fed between the breast milk and the infant formula during the 1st year after birth and the duration of feeding. There was no significant difference in dmfs between the breast milk group and the infant formula group(significance level 0.05, same below). Tooth groups, tooth surface groups, teeth, and tooth surfaces which had significantly higher dmfs in the breast milk group than in the infant formula group were upper anterior teeth(tooth groups), upper incisors' buccal and proximal surfaces(tooth surface groups), upper incisors and upper second molars(teeth), upper central incisors' buccal and distal surfaces, upper lateral incisors' buccolingual and proximal surfaces, upper 2nd molars'lingual, proximal, and occlusal surfaces, and lower 2nd molars' buccal and distal surfaces. In the breast milk group, tooth groups, tooth surface groups, teeth, and tooth surfaces which dmfs significantly increased as the duration of the feeding increased were upper anterior teeth and upper molars(tooth groups), upper anterior teeth's proximal surfaces, upper molars' buccolingual, proximal, and occlusal surfaces, lower molars' proximal surfaces(tooth surface groups), upper anterior teeth, upper molars, lower 2nd molars(teeth), upper anterior teeth's proximal surfaces, upper 1st molars'buccolingual, proximal, and occlusal surfaces, upper 2nd molars' buccal surfaces, and lower 2nd molars'mesial surfaces(tooth surfaces). In the infant formula group, dmfs increased after 3 years of feeding, but the difference was not significant. Caries prevention is necessary in case of breastfeeding more than two years. |
