Relation in color of three regions of vital human incisors

Objectives. For an adequate color reproduction, it is very valuable to quantify the color distribution in human teeth accurately. The aim of this study was to determine the color relation between three tooth segments (cervical, middle and incisal) in vital upper central incisors, using digital photography. Methods. Digital recordings of 64 upper right central incisors were made using a standardized head-camera setup. The L* a* b* values of three regions were attained from the standardized digital images using software. Results. There were statistically significant linear correlations for L* and b* between the three tooth segments (all r’ s≥0.60; p
