High-temperature adhesives are considered for high-temperature applications such as the refractory industry. In this research, inorganic high-temperature phosphate-based adhesive was prepared using alumina and micro silica as the main raw materials and monoaluminum phosphate as a binder. The effect of firing temperature on the properties of the adhesive including phases, microstructure, compres...

Background and Aim: Fractured metal-ceramic restorations may be repaired with composite in some cases to postpone the fabrication of a new restoration. Knowledge about the bond strength can help predict the success rate of this treatment modality. The aim of this study was to assess the effect of two types of mechanical surface treatment of metal along with the use of different adhesive systems...

Background and Aim: Preparation of tooth structure by laser systems produces a surface with different characteristics. Therefore, selecting an appropriate bonding system is necessary to achieve the maximum bond strength. The aim of this study was to compare the bond strength of Adper Single Bond 2 adhesive and Single Bond Univer-sal to dentin prepared by bur or laser. Materials and Methods: ...
