Description
Tuğba Aycan Erkal and Mehmet Uğur published a 2026 laboratory study of how computer-made dental restorations age under years of toothbrushing. Forty-eight disc specimens, twelve each from four CAD/CAM materials ranging from feldspathic ceramic to resin composite, were brushed in a simulator at loads matching one, three, and five years of use. Color change was scored with a standard formula and gloss measured directly.
Every material changed significantly in color and gloss in the reported analysis. Feldspathic ceramic changed least and kept the most gloss after five simulated years, while polymer-infiltrated ceramic and resin-based materials dulled and shifted more. A zirconia-reinforced ceramic changed early, then stabilized, and all color shifts stayed within clinically acceptable limits, so composition, not acceptability, separated the materials.
