summary The objective of this study was to test inter‐observer variability in shade selection for porcelain restorations, using three different shade guides: Vita Lumin Vacuum, Vita 3D‐Master and Procera. Nineteen young dental professionals acted as observers. The results were also compared with those of a digital colorimeter (Shade Eye Ex; Shofu, Japan). Regarding repeatability, no significant differences were found between the three shade guides, although repeatability was relatively low (33–43%). Agreement with the colorimetric results was also low (8–34%). In conclusion, shade selection shows moderate to great inter‐observer variation. In teaching and standardizing the shade selection procedure, a digital colorimeter may be a useful educational tool.
