The influence of the resin?based cement layer on ceramic?dentin bond strength

The purpose of the study was to measure cement thickness obtained when ceramic rods were luted dentin and analyze relation between previously published tensile bond strength similar test specimens. In addition, ISO standard 4049:2019 method used determine film cements. Zirconia (n = 100) lithium disilicate 50) cemented bovine using one five different resin-based ceramic-dentin specimens cut into two slices measured a scanning electron microscope compared values already published. mean recorded for in range 20–40 ?m, which larger than found by method. determined according methods did not concur with results cementing dentin. For restorations, 25–35 ?m seems be favorable strength.
