Statement of Problem: Whenmultiple teeth aremissing, the color formissing teeth shouldbe estimatedbased onthe colorof remaining teeth. Purpose: The purposewas to determine the strength of color correlations among six types of permanent anterior teeth. Methods: Colorof12 anterior teethwasmeasuredby ShadeVision Systemfor 47 volunteers.The colorcoordinates in eachtype ofteeth such asmaxillarycentral incisor (MX1), lateral incisor (MX2), and canine (MX3), andmandibular central incisor (MD1), lateral incisor (MD2), and canine (MD3) were determined.Correlations and differences among the correspondingcolorcoordinates of eachtype ofteethwere determined. Results: Comparedwith MX1, the differenceswere inthe range of 23.2 to 26.5 in L*,0.5 to 2.7 in a*, 20.7 to 7.5 in b*, and the colordifference (DE*ab) was 4.5 to10.3.The colordifference by DE00 formulawas 3.1^6.7.Althoughthe colorcoordinateswere different by toothtype, theygenerally showed correlations (p< 0.001). Conclusions: For the colorestimation ofmissing MX1, the colorcoordinates of MD1were the strongestpredictors.In case ofmissing MX3, L* and a* of MD3 and b* of MX1were the strongestpredictors for each corresponding coordinates. CLINICAL SIGNIFICANCE The color formissing teeth, especially formaxillarycentral incisor andmaxillary andmandibularcanines, couldbe estimatedbased onthose ofthe same type teeth onthe opposingarch.These results should be applied forclinical color selection formissing teeth.
