초록

이 연구의 목적은 상악 유중절치를 절단, 중간, 치경부로 나누어 각 부위의 색조 분포 및 각 부위 색조 사이의 관계를 분석하는 것이었다. 3세에서 6세 어린이의 건전한 상악 유중절치의 색조를 분광광도계를 이용하여 측정하였다. CIE $L^*$, $a^*$, $b^*$, $C^*$, $h^*$ 및 이에 가장 잘 맞는 shade가 각 부위와 전체 순면에 대해 얻어졌다. 각 부위 및 전체 순면에 대해 CIE $L^*$, $a^*$, $b^*$는 유의한 차이가 있었고(p < 0.05) 각 부위 사이의 색조 차이는 임상 허용의 한계치 보다 컸다. 각 부위의 색조 사이의 관계를 $L^*$, $a^*$, $b^*$ 값 사이의 관계로 정리하면 한 부위의 색조로 다른 부위의 색조를 예상하거나 유치의 색조에 더 잘 부합하는 수복 재료 및 보철물을 제작하기 위한 자료로 활용할 수 있다.

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.
