초록
The purpose of this study was to analyze the color distribution of the maxillary primary central and lateral incisors using a dental spectrophotometer. Color measurements of maxillary primary central and lateral incisors of 32 pediatric patients aged 2 to 6 years were performed using SpectroShade Handy Dental Type 713000 (Serial No. HDL2678, MHT, Verona, Italy) by one researcher in the same clinic. CIE L*, a*, b* values of total surfaces and cervical, middle, incisal region were recorded. L* values were higher and a* values were lower in the primary central incisors than those in primary lateral incisors, but b* values didn’t show statistical difference. L* values of the middle region were the highest, and a* and b* values decreased from the cervical region to the incisal region. There were significant color differences between each region, and ΔE* ab between each region were greater than ΔE* ab between the primary central and lateral incisors. For esthetic restorations of primary incisors, it is necessary to consider the color differences between each region rather than those between the primary central and lateral incisors.
