Abstract: Objective To study the colorimetric board of porcelain fused to metal (PFM) restorations for severe dental fluorosis. Methods 300 pieces of metal plates with different dyeing formulations of glazed ceramic powder were fabricated. The colorimetric parameter values of these colorimetric plates were determinate by Shade Eye-NCC (the 2nd generation computer colorimetric instrument), and the values were compared with fluorosis values of tooth-colored degrees. Results The colors of group B 4, 5 plate, group F 2, 4, 5 plate, and group G1 plate were clinically acceptable. Conclusion The metal-based colorimetric boards in this study might be a new method to make shade guide for fluorine spot teeth.

Key words: Dental fluorosis, Extrinsic stain, Shade guide, Chromaticity
