TLDR
Polishing with rubber points followed by felt disks impregnated with a fine-aluminum oxide particle resulted in biofilm formation similar to that present with a glazed ceramic surface, even though the surface is still rougher and more hydrophobic.Abstract:
Clinical Relevance When the glazed surface of glass ceramics is submitted to chairside preparation, polishing with rubber points followed by felt disks impregnated with a fine-aluminum oxide particle appears be a good option to polish the surface of the glass ceramic, since this finishing-polishing method results in biofilm formation similar to the glazed ceramic surface.read more

Does Finishing and Polishing of Restorative Materials Affect Bacterial Adhesion and Biofilm Formation? A Systematic Review.
Dam Dutra,G.K.R. Pereira,Karla Zanini Kantorski,Luiz Felipe Valandro,Fabricio Batistin Zanatta +4 more
TL;DR: The impact of roughness on bacterial adhesion seems to be related not to a roughness threshold but rather to a range, the range of surface roughness among different polishing methods is wide and material dependent, finishing invariably creates a rougher surface and should always be followed by a polishing method and in vivo and in situ designs become strongly recommended.

Morphology and bacterial colonisation of tooth/ceramic restoration interface after different cement excess removal techniques

TL;DR: The brush technique seems to be a good option for removing the excess resin cement after adhesive cementation in clinical practice, as indicated by its better results with lower bacterial colonisation.

TL;DR: Assessment of the ceramic surface smoothness achieved with various commercially available ceramic polishing kits on different commonly used ceramic systems found no correlation could be established between the high cost of the polishing kit and low surface roughness.

TL;DR: The manually polished glass CAD/CAM ceramics promoted lower surface roughness than did the glazed feldspathic dental Ceramics and the mean roughness values were significantly affected by the ceramic type and polishing technique.

Surface Characteristics and Biofilm Development on Selected Dental Ceramic Materials.
TL;DR: This study correlated surface roughness to biofilm development with four commercially available ceramic materials and found that adjusted materials with the exception of Vitablocs Mark II promoted significantly greater biofilm growth relative to controls.

TL;DR: Analysis of biofilms of P. aureofaciens growing on 0.03 mM, 0.1 mM or 0.5 mM citrate minimal media showed that mean biofilm thickness increased with increasing citrate concentration, whereas surface to volume ratio increased with higher citrate concentrations.

LIVE/DEAD® BacLight™: application of a new rapid staining method for direct enumeration of viable and total bacteria in drinking water
TL;DR: A rapid epifluorescence staining method using the LIVE/DEAD Bacterial Viability Kit was applied to estimate both viable and total counts of bacteria in drinking water, and the increase in environmental stresses induced a decrease in viability that was more pronounced for CTC and plate counts than for BacLight viable counts.

TL;DR: In this paper, the influence of surface roughness and surface free energy on supragingival plaque formation has been examined in the oral cavity and in vitro and in vivo studies underline the importance of both variables in plaque formation.

TL;DR: In this article, a clinical trial was conducted to explore the "relative" effect of a combination of these surface characteristics on plaque growth, and the results showed that a significant difference in plaque accumulation was only obtained when a rough surface was compared with a smooth surface.
