- Abstract
This study aims to evaluate the effects of the new generation light curing devices and different adhesive systems on the shear repair strength between amalgam and resin composite. Ninety-six square-shaped amalgam (Cavex Non Gamma-2; Cavex Holland BV, Haarlem, the Netherlands) samples were prepared. The amalgam surfaces were polished with 600-grit abrasive paper. The prepared amalgam samples were divided into four groups (Single Bond Universal, 3M ESPE; Adper Easy One, 3M ESPE; Prebond SE, President Dental; OptiBond All-in-One, Kerr) according to the adhesive brand. Each adhesive group was divided into two subgroups according to the 3rd generation light curing devices (Elipar DeepCure-S [3M ESPE, USA], VALO Cordless [Ultradent, USA]) (n = 12). Microhybrid composite cylinders of 3 mm height and 2 mm diameter were placed on the amalgam surfaces by layered method with a silicone mold (Dynamic Plus; President Dental, Germany). Each layer was polymerized with a group specific light curing device. The samples were incubated in distilled water at 37 °C for 24 h before the shear-bond-strength test. The shear bond strength test was accomplished using a universal testing device. Statistical analyzes were made with two-way ANOVA and Tukey HSD tests. Two-way ANOVA revealed a significant effect of the adhesive system brand on bond strength (p < 0.00). Prebound SE provided the lowest bond strength between both light curing devices groups. There was no significant difference between the two light-curing devices groups among Single Bond Universal, Adper Easy One and OptiBond All-in-One resin adhesive systems. It has been revealed that the high-intensity LED light curing device brand does not have a significant effect on the amalgam-resin composite repair strength, and the repair strength may be more affected by the brand of the adhesive system used.
