The effect of surface roughness on ceramics used in dentistry: A …
The surface structure and composition of a dental restorative material influences the initial bacterial adhesion, and a rough material surface will accumulate more plaque. Biomaterials for the restoration of oral function are prone to biofilm formation, affecting oral health.
Evaluation of the effect of different polishing systems on the surface ...
2020年7月1日 · The surface roughness of opposing enamel in occlusal contact areas is stated to be 0.64 μm 48 and is a clinically important reference for the surface roughness of a restoration. The definitive surface roughness values obtained for all ceramic types in this study were lower than the enamel roughness in occlusal contact areas; hence, it can be ...

2014年10月1日 · In this study, Tetric N-Flow and Beautifil-Bulk Flowable showed the highest values of surface roughness, followed by Z350 XT Filtek Universal Restorative, while Filtek Bulk Fill Flowable ...
Evaluation of the Surface Roughness in Dental Ceramics …
In this study, the mean surface roughness values (Ra) found for the ceramics submitted to different finishing and polishing systems presented no statistically significant differences in comparison with the groups that were not polished, except the groups polished with the abrasive rubber system sequence (Shofu) in VM7 and VM9 ceramics, while ...
(PDF) The effect of surface roughness on ceramics used in …
Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth. This study correlated surface roughness to biofilm development with four commercially available ceramic materials.
Surface Roughness in Ceramics with Different Finishing Techniques …
2006年7月1日 · This study evaluated the surface roughness of 3 different brands of ceramic materials when modified by different intraoral polishing procedures, as compared to a thermally-glazed control group. The specimens were quantitatively evaluated with a profilometer and an atomic force microscope with respect to Ra (average roughness) and Ry (maximum ...
Assessment of enamel surface roughness and hardness with …
2023年9月1日 · This study aimed to evaluate enamel surface roughness and microhardness following the use of different bracket materials (metal or ceramic), etchants (total- and self-etchants), and adhesive systems (precoated or flash-free). A total of 99 extracted human premolars were selected for the analysis.
Experimental Study of Surface Roughness of Dental Ceramics …
This study evaluated the surface roughness of three dental ceramics after polishing with three types of extraoral ceramic polishing sets. One hundred and twenty specimens were fabricated from feldspathic porcelain, lithium disilicate, and zirconia ...
ental surface condition are investigated. The surface roughness of the used ce-ramics and its long term changes carry important information for the ceramics’ quality a. rials is comprehensively reviewed in [2]. To evaluate the effect on the roughness, controlled clinically simulated intraoral grinding and polishing of two ty.
Effect of surface treatment on enamel surface roughness
2016年1月12日 · Several studies in the literature have evaluated the roughness of human primary and permanent teeth (3), the effect of microabrasion on the surface roughness of restorative materials, dentin and enamel (4, 5), the correlation between enamel roughness and wettability (6), and the influence of various methods of ceramic surface etching on roughnes...
