The specimens were kept in incubator for 24 h at 37°C, aged by thermal cycling 1000 times between 5–55°C. The specimens’ surfaces were finished with coarse diamond burs and randomly divided into 4 groups (n = 12) with respect to different surface conditioning methods: etchant+universal adhesive (All-Bond Universal, Bisco), universal adhesive, alloy primer (Z-Prime, Bisco)+universal adhesive, self-adhesive resin cement (BisCem, Bisco). The old amalgam specimens were placed into plastic tubes (4 mm diameter × 8 mm height) and all adhesive systems were used according to manufacturer’s instructions. Resin composite (Charisma Classic, Haraeus Kulzer) was placed and polymerized 20 s. The samples were incubated in distilled water at 37°C for 24 h prior to the shear-bond-strength test. The shear-bond-strength test was accomplished using a universal testing device. Statistical analyzes were made with One-way ANOVA and Tukey HSD tests. There was no significant difference between self-adhesive resin cement and alloy primer applied groups but showed better bond strength values than self-etch and etch&rinse adhesive applied groups. The application of self-adhesive resin cement and alloy primer+universal adhesive in amalgam repair exhibited successful outcomes.
