dc.description.abstract | PURPOSE. To evaluate the polishing effect on roughness and color change of pressed and layering ceramics after immersion in coffee solution. MATERIALS AND METHODS. 88 ceramic discs (1.0 mm x 10.0 mm) were manufactured - 44 nano-fluorapatite layering ceramics (IPS e.max Ceram. Group C) and 44 pressed lithium disilicate ceramic discs (IPS e. max Press - Group P). Each group was divided into 4 subgroups according to surface treatments: (G) Glaze, (S) Shofu polishing system (Shofu Inc.), (E) Edenta AG polishing System, (KG) 30-pm diamond granulation tip. Surface roughness (Ra) and color change (Delta E) measurings after the surface treatments were performed, before and 12 days after the immersion in coffee solution. A sample's qualitative analysis was conducted with a scanning electron microscopy (SEM). Data were statistically-treated with oneway-ANOVA and Duncan's tests, apart from paired t-test and Pearson's correlation test (alpha=5%). RESULTS. The decrescent order, both for surface roughness (Ra) and Delta E for both ceramics were: KG > E > S > G (P<.05). With exception for PG and CG subgroups, which did not present statistical difference between them, all other pressed ceramics subgroups presented smaller Ra values and greater Delta E values than the layering ceramics subgroups (P<.05). CONCLUSION. Although mechanical polishing systems presented intermediate Ra values, their colors were considered clinically acceptable. There is a strong correlation between the surface roughness and the color change of tested ceramics. | en |
