Assessing Color Inconstancy of CAD/CAM Materials: Influence of CIE White LED Illuminants and Substrate Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To assess how the CIE white LED illuminants and substrate shade impact the color inconstancy of high‐translucency CAD/CAM materials. Materials and Methods From the spectral reflectance factors of Lava Ultimate‐LU, Grandio blocks‐GB, VITA Enamic‐VE, and VITA Mark II‐M specimens (n = 3/material) measured on nine background shades (ND1 ...

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Evaluation of the Integrity of Ceramic Laminates After Adhesive Cementation

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of resin‐based materials on crack occurrence in ceramic laminate veneers (CLVs) after adhesive cementation. Additionally, the polymerization shrinkage stress (PSS) and maximum polymerization rate (MPR) of the resin‐based materials were determined. Materials and Methods Four resin‐based materials were
