The purpose of this study was to evaluate the color of primary teeth. A Vita Easyshade intraoral spectrophotometer was used to determine the color of primary teeth: (1) maxillary central incisors, canines, and first molars; and (2) mandibular central incisors, canines, and first molars. A total of 604 teeth were measured. Color difference was compared to DeltaE*=2.7 (mean=50:50 replacement point). Coverage error (DeltaE*cov) was calculated. Mean L*a*b*C*ho values for primary teeth were 82.5, 0.2, 18.3, 18.4, and 89.4 respectively. The most frequently chosen shades were A1 (46%), A2 (25%), and B2 (11%). Canines had the highest lightness. Maxillary canines had the lowest a* values, whereas mandibular primary incisors had the highest a* values. Molars were the most chromatic (having the highest b* values), followed by canines and primary incisors in decreasing order. Coverage error (DeltaEcov*) of Vitapan Classical was 4.2 (+/-1.9 SD). Among primary teeth, the widest ranges, in order, ...
