TLDR
It was concluded that the Edenta and Shofu abrasive tips are more effective in reducing the surface roughness of ceromers compared with the Enhance silicone tip.Abstract:
Objective: This in vitro study evaluated the effects of three polishing systems on the surface roughness of two ceromers Material and Methods: 96 specimens (8 mm in diameter and 2 mm thick) were prepared in a metal mold using two restorative materials: CERAMAGE (Shofu, Japan) and VMLC VITA (VITA Zahnfabrik, Germany) The specimens were divided into 4 groups (n=12): G1: positive control, Mylar strip; G2: abrasive tips, Edenta system; G3: silicon tips, Enhance system; and G4: abrasive tips, Shofu system The parameter evaluated was the average surface roughness (Ra) determined by using a profilometer SJ 301 (Mitutoyo, Japan), followed by photographic evaluation images through Scanning Electron Microscopy (SEM), with a 1000x magnification range The data was subjected to statistical analysis for comparison between the groups (ANOVA, Tukey and Student T-tests), with a significance level of 5% Results: there was a statistically significant difference between the silicone tip Enhance and the other groups for both ceromers with higher values of surface roughness There was no statistically significant difference between the ceromers, except for the Shofu system, which showed lower values of surface roughness for Vita VMLC Conclusion: Within the limitations of this study, it was concluded that the Edenta and Shofu abrasive tips are more effective in reducing the surface roughness of ceromers compared with the Enhance silicone tip Keywords: Resins; Surface roughness; Dental polishingread more

TL;DR: O ceromeros e polimeros de vidro can be used isoladamente in determinados trabalhos proteticos, such as inlays, onlays and coroas, ou combinados a fibra de vodro reforcada (FRC) o que aumenta a resistencia desses materiais, substituindo as ligas metalicas em casesos selecionados as discussed by the authors.

Comparison of surface roughness of oral hard materials to the threshold surface roughness for bacterial plaque retention: a review of the literature
TL;DR: The range in surfaceroughness of different intraoral hard surfaces was found to be wide, and the impact of dental treatments on the surface roughness is material-dependent.

TL;DR: Bacterial adhesion to indirect composite resin materials differed from that to ceramic material after surface treatments, and a positive correlation was observed between surface roughness and the vital S. mutans adhesion.

TL;DR: The weights of artificial plaque on all filling materials tested were higher than those on ceramics, the highest values were measured on the glass-ionomers, and there was no correlation of the surface roughness with the number of colony-forming units of S. mutans.
