Taha Yasar Manav, Ayse Karabas, Hakan Kamalak

Background: The color options of natural teeth and restorative materials have critical applications in clinical dental practice and research. This review provides information about the comparison of current color measurement techniques in dentistry. Material-method: Forty-four volunteers between the ages of 18 and 22 were included in this study. Shade selection was performed from the upper right central incisor using the VITA Classical (VITA Zahnfabrik, Germany) shade guide and the VITA Easyshade V spectrophotometer (VITA Zahnfabrik, Germany) in clinical setting. Photographs were taken using a smartphone (Apple iPhone XS), Smile Lite MDP (Smile Line, Switzerland) and gray card (Flexipalette Color Match, Smile Line, Switzerland), then color measurement was evaluated with software. The measurements were evaluated using CIELab color coordinates and ΔE value. Results: The ΔE value was statistically significant in this study compared to the groups. (p=0.001; p<0.01). In addition, it was found that the ΔE value of both dental photography groups was high compared to both shade guide groups (p=0,001; p<0,01). According to the groups, the L*, a* and b* values showed statistically significant differences (p=0.001; p<0.01). Conclusions: While there was a subtle difference between analysis techniques, the spectrophotometer is more accurate than other methods in color selection.
