The Wear Behavior of Glass-Ceramic CAD/CAM Blocks against Bovine Enamel

Materials, 2023
The wear of enamel and crown restorative materials often occur by occlusion. The purpose of this study was to evaluate the wear volume between glass-ceramics used for CAD/CAM blocks (lithium disilicate: Initial LiSi block (LIS), IPS e.max CAD (IPS), zirconia-reinforced lithium silicate glass-ceramics: Celtra DUO (DUO), VITA Suprinity (VITS) and ...

The effect of Phytosphingosine and bioactive glass-ceramics in preventing dental enamel erosion

Brazilian Dental Journal, 2023
Abstract This study evaluated the effect of phytosphingosine (PHS) and bioactive glass-ceramic (Biosilicate) on dental enamel in terms of color alteration (ΔE), microhardness, and surface roughness when submitted to erosive challenge (EC). Sixty specimens of bovine teeth (6×6×2mm) were obtained.

After bleaching enamel remineralization using a bioactive glass-ceramic (BioSilicate®)

Biomedical glasses, 2016
AbstractTooth bleaching agents may weaken the tooth structure, therefore, it is important to minimize any risks of enamel and dentine damage caused by them. In this way, different materials have been used to avoid or minimize the tooth damage during bleaching.
