Effect of 4-(methymercapto) benzaldehyde (MTAD) pretreatment on microtensile bond strengths of two resin cements on dentin surface

Abstract

The aim of this study, as pretreated by MTAD, is to evaluate the resin adhesive strength. Samples were divided four groups: untreated dentin, dentin surface treated with tri-steamed water, dentin surface treated with phosphoric acid, dentin surface treated with EDTA, and dentin surface treated with MTAD. These were then glued to the pulp using two resins: Panavia F 2.0 and Relyx Unicem. This setup was is placed in water and divided and then It subjected to SEM characterization. The binding strength of MTAD-treated teeth was higher than that of the other three groups. After MTAD treatment, the adhesive force of the two resins on the tooth surface was greatly enhanced.
