title: [Effect of glazing techniques on color of porcelain-fused-to-titanium restorations].
abstract: OBJECTIVE
  To study the effect of various glazing techniques on color of porcelain-fused-to-titanium restorations and their surface texture.
  
  
  METHODS
  Standard samples of Dentsply Tibond porcelain fused-to-metal restorations were made. Selfglazing and over-glazing techniques were used. Color parameters were tested by cs-5 spectrophotometer with CIE1976LAB color system before and after glazing. Statistical analysis was done and the color differences were calculated. The samples' surface structure was observed under the same background.
  
  
  RESULTS
  No statistical significance existed in all of the color parameters between two groups before and after glazing. The values of color difference were all smaller than 1.5. The samples had the same surface structure after treated by different glazing techniques.
  
  
  CONCLUSIONS
  Glazing techniques had no effect on final color of porcelain-fused-to-titanium restoration. No matter what kind of glazing techniques were used, the same surface structure and color would be obtained as long as the same polish way was used before glazing.
