Purpose: This study was evaluated the shade of feldspathic porcelain with various concentration of silver ion.

Materials and Methods: The control group was conventional feldspathic porcelain with no silver ion, the experimental groups were the feldpathic porcelain with 5%, 10%, 20%, 30% silver ion. The number of specimens on the each group was 5. Commission Internationale de I¡¯Eclairage (CIE) L*a*b* parameters were recorded twice for each specimen with a spectrophotometer (Model CM-2600d, Minolta, Japan). One-way Anova was used for statistical analysis.

Results: L value was similar. a value was increasing and b value was decreasing with silver ion statistically significantly. ¥ÄE was increasing according to silver ion significantly.

Conclusion: The shade of feldspahtic porcelain was influenced by silver ion. Ag ion under 10% concentration is acceptable clinically.
