RESUMO
The purpose of this study was to evaluate the relationship between Body Mass Index (BMI) and dental caries by considering related factors in Korean children and adolescents. A total of 2,874 children, aged from 2 to 18, who participated in the Korea National Health and Nutrition Examination Survey 2013 – 2015 were included. BMI (kg/m²) was calculated, and participants were categorized into 4 groups using age and gender specific criteria. Decayed and filled teeth index were obtained. There were statistically significant differences in DMFT index between overweight group and other groups (p < 0.01). Underweight group showed the highest mean DMFT index compared to other groups. These findings suggest that children in obesity and underweight group tend to have more caries than normal group in this study.

The objective of this study was to analyze the color distribution of the maxillary primary central incisors and the relationship between the color of each tooth region by dividing tooth into incisal, middle and cervical region using a spectrophotometer. The subjects were 105 sound maxillary primary central incisors from 3 to 6 years old children. Color measurements were performed by one dentist using same protocol. CIE L* , a*, b*, C*, h* data and the best matched shades with coverage error were obtained for each region and whole labial surface. There was a significant difference in CIE L* , a*, b* according to regions and the difference in color between each region was more than the clinical acceptance. By correlating the relationship between the color of each region with L*, a*, b* values, it is possible to extrapolate the color of other region with one color or to be used as data for making restorative materials and prostheses that are more aesthetically pleasing for primary teeth.
