Abstract

Aim and objective: Compare the reliability and accuracy of shade selection done by the male observer and female observer with a digital shade matching device. Materials and methods: Tooth color was measured in 39 volunteer\'s maxillary right and left central incisor teeth with Vita classic shade guide by two different observers (male and female) against a digital shade matching device (Vita Easyshade compact). L, C, and H values and ΔE value determined by visual method using Vita classic shade guide against digital shade matching system (Vita Easyshade compact). ANOVA and Bonferroni multiple comparison statistical analyses were used to compare the data. Results: There was very little significant difference between shade selected by male and female observers against Vita Easyshade compact with respect to L, C, and H value (p < 0.001). ΔE shows a significant device difference where Vita Easyshade compact has the highest mean of 3.113 followed by Vita classic has least mean value of 2.475. Conclusion: Determining the shade of a tooth demands clinical skills and experience. The females achieved better results in terms of shade selection as they are more conscious about esthetics.
