Abstract |
The purpose of this study was to investigate the dental caries prevalence and occlusion pattern of children with deciduous dentition in Chonnam seashore area. Two thousand two hundred seventy two kindergarten children ranged 3 to 5 years of age were examined. The obtained results were as follows : 1. The rate of children with caries experience(dmf rate) in deciduous teeth was 66.8% at 3 years of age, 77.7% at 4 years of age, and 83.5% at 5 years of age and showed no significant gender differences(p>0.05). 2. The mean number of decayed, missing, filled deciduous teeth(dmft index) was 3.62 at 3 years of age, 4.73 at 4 years of age, and 5.96 at 5 years of age and showed no significant gender differences(p>0.05). 3. Most of the caries-prevailed tooth was mandibular 2nd primary molar and showed 39.48% at 3 years of age, 49.73% at 4 years of age, and 63.85% at 5 years of age. 4. The caries-experienced teeth in order were as follows : mandibular 2nd primary molar with 52.34%, mandibular 1st primary molar with 45.61%, maxillary 2nd primary molar with 38.81%, and maxillary primary central incisor with 38.86%, respectively. 5. In sagittal primary molar relationship, Class 1 occlusion pattern was 53.26%, Class 2 pattern was 1.41% and Class 3 pattern was 30.02%, respectively. Right Class 2 and Left Class 3 pattern was not observed. |
