Key Points

To evaluate the impact of toothpaste and thermal aging on the surface roughness and stain durability of stained zirconia.
Compared additively manufactured zirconia to subtractively manufactured zirconia and lithium disilicate.
Used variations of toothpaste and subjected samples to thermal cycling.
Assessed color change and surface roughness after treatments.
Findings show similar surface roughness across materials after treatment.
Color changes were noted as moderately unacceptable after thermal cycling and brushing with toothpaste.
