    Author: Wu X, Ma Y.
    Journal: Zhongguo Yi Xue Ke Xue Yuan Xue Bao; 2000 Feb; 22(1):90-2. PubMed ID: 12903504.
    Abstract:
    OBJECTIVE: To study the effect of titanium substructure on color of porcelain-fused-to-metal restoration. METHODS: Standard samples of Dentsply DETREY-Carat and Tibond porcelain fused-to-metal restorations were made. Color Parameters were tested by cs-5 spectrophotometer. Statistic analysis was done and the color differences were calculated. RESULTS: Most of color parameters were found to be statistically significant at the P < or = 0.05 level at substructure layer. But no statistical significance existed after putting opaque and dentin porcelain. The values of color difference between two groups at opaque and dentin porcelain layers were all smaller than 1.5. CONCLUSIONS: Titanium substructure had no visually apparent effect on final color of porcelain-fused-to-metal restoration. There was no perceived color difference between corresponding shade of two Dentsply porcelain systems (DETREY-Carat and Tibond).
