Abstract

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. DeltaE 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.
