Color match and stability
Tidsramme: 24 months
|
Clinical evaluation of color match and color stability will be performed according to the World Dental Federation (FDI) evaluation criteria by two calibrated evaluators at baseline and at 6, 9, 12, and 24 months.
Veneer restorations will be assigned FDI scores ranging from 1 (clinically excellent) to 5 (clinically poor).
Clinical success will be considered as scores of 1-3 and failure as scores of 4-5.
Assessment will be carried out under standardized lighting conditions using visual examination and magnification.
Statistical analysis will be performed to compare changes over time and between the two study groups.
