Purpose: The purpose of this study was to spectrophotometrically evaluate the shade difference between of maxillary and mandibular anterior teeth in the Korean by the standard of vita classical shade guide using SpectroShadeTM.

Material and methods: In this study, the shades of healthy anterior teeth were examined and analyzed using the digital shade analysis of SpectroShadeTM. This study examined 80 individuals in their twenties, thirties, fourties, fifities ages and 40 males and 40 females, presenting 12 healthy, unrestored maxillary and mandibular anterior teeth. Tooth brushing and oral prophylaxis were performed prior to evaluation. The SpectoShadeTM was used to acquire images of
the 12 maxillary and mandibular anterior teeth. These images were analyzed using SpectroShadeTM Software, and shade maps of each tooth were acquired. The shade difference of upper and lower, and gender differences and ages difference were investigated and analyzed with CIE L*a*b* color order system. One-Way ANOVA test was used to find out if there were significant differences between groups tested and Sheffe multiple comparison was used to identify where the differences were.

Results: 1. Shade differences were significant (P £¼ .05) between maxillary and mandibular central incisor, lateral incisor, canine. 2. No significant differences in shade distribution were seen between lateral incisors and central incisors. 3. Canine¡¯s shade difference were more significant than central incisor¡¯s and lateral incisors¡¯s. 4. No significant differences in shade distribution were seen between genders in maxillary and mandibulr central incisor, lateral incisor, canine. 5. No significant differences in shade distribution were seen in order of years in maxillary and mandibulr central incisor, lateral incisor, canine.

Conclusions: The results of this study show that 1. Shade difference was founded in maxillary and mandibular anterior teeth and ¥ÄE* value was more than 2.0. 2. Canine¡¯s shade difference were more significant than central incisor¡¯s and lateral incisors¡¯s and between central incisors and lateral incisors shade differences were no significant. 3. No significant differences in shade distribution were seen between genders in maxillary and mandibular anterior teeth. 4. No significant differences in shade distribution were seen in order of years grade in maxillary and mandibular anterior teeth.
