Are there any differences in physical properties among shades, or shade groups?
With the exception of radiopacity, all 4 Seasons materials possess the same physical properties (e.g. flexural strengths, compressive strengths, Vickers hardness, wear abrasion, etc.) providing the restoration with durability and longevity regardless of what material is used on the surface of the restoration. For example, even the Enamel Trans Super Clear shade, with a translucency value of 56.6%, boasts the same physical properties as the dentin shades.
