- Abstract
- This in vitro study evaluated the effect of
tooth brushing and thermal cycling on the surface
lustre and surface roughness of three ceromer systems
treated with different surface finishing methods.
The ceromers studied were: (1) Artglass, (2)
Targis, (3) Sculpture and (4) the control group, Z100.
Half of the Targis and Sculpture groups were
polished and the rest were coated with staining
and glazing solution, respectively. All specimens
were subjected to thermocycling 10 000 times. Tooth
brushing abrasion tests were performed in a customized
tooth-brushing machine with 500 g weight
applied on a back-and-forth cycle for 20 000 repetitions.
The lustre determined by measuring the light
reflection area and the average roughness was
compared between groups and between pre- and
post-test values. All materials showed a lower lustre
and rougher surface after thermocycling and tooth
brushing (P < 0Æ05). All ceromer specimens, except
glazed Sculpture, showed a higher lustre and similar
roughness to the control group. The post-brushing
results revealed that glazed Sculpture presented
discretely fallen out glaze coatings and had maximum
change. However, stained Targis showed
minimum change (P < 0Æ05) and polished Targis
presented more changes than that of the staining
treatment. It is therefore concluded that the glaze
coatings for Sculpture dont exhibit long-term durability,
while stain coatings for Targis acted like a
protective layer.
