Hydrothermal ageing may increase surface roughness but not affect translucency in various zirconia ceramics
Hydrothermal ageing may increase surface roughness but not affect translucency in various zirconia ceramics suggests a recent study published in the European Journal of Dentistry. This study investigated the effect of hydrothermal aging on surface roughness and translucency of various translucent zirconia materials.
Groups 1 and 2 showed significant increased surface roughness after aging while groups 3 and 4 showed no alteration of surface.
There was no effect of aging on translucency in all groups.
After aging, group 1 and 2 presented monoclinic structure (16.63 and 5.01%, respectively).
Hydrothermal aging caused phase transformation and increasing surface roughness in group 1 and 2 but did not affect translucency in all groups.
