摘要: 目的 研制适合临床中重度氟斑牙烤瓷修复比色用的比色板。方法 制作300块金属基底比色板,B组、F组、G组各100块,用5种配方的外染色瓷粉进行上釉染色。用Shade Eye-NCC第2代电脑比色仪测定不同配方制作的比色板的色度学参数值,比较其与中重度氟斑牙的色差。结果 B组4号和5号配方,F组2、4、5号配方和G组1号配方的金属基底比色板与中重度氟斑牙的色差小于临床可接受的色差值。结论 本研究制作的金属基底比色板为中重度氟斑牙烤瓷修复的比色提供了新的方法。

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.
