The purpose of this study was to evaluate the color of anterior primary teeth.
A total of 449 teeth (including central and lateral incisors) belonging to 78 3- to 6-year-olds were evaluated. A spectroscope was used to determine tooth color. Each tooth's overall shade and the respective shades in the cervical, middle, and incisal thirds were measured, and data collected was subjected to statistical analysis.
D2 was found to be the most common shade of primary teeth. Comparing B1, D2, and C1 shades using a chi-square test showed statistically significant (P<.001) differences among children.
D2 was the most common shade of primary anterior teeth in children.
本研究旨在评估乳前牙的颜色。
对78名3至6岁儿童的总共449颗牙齿（包括中切牙和侧切牙）进行评估。使用分光镜确定牙齿颜色。测量每颗牙齿的整体色泽以及颈部、中部和切端三分之一处的各自色泽，并对收集的数据进行统计分析。
发现D2是乳牙最常见的色泽。使用卡方检验比较B1、D2和C1色泽，结果显示儿童之间存在统计学上的显著差异（P<.001）。
D2是儿童乳前牙最常见的色泽。
