Clinical Relevance To restore endodontically-treated molars, the use of indirect hybrid inlay restorations may be recommended due to their more favorable fracture failure modes compared with amalgam, resin composite and fiber-reinforced resin composite restoration techniques and their greater fracture resistance compared with amalgam restorations.

Clinical Relevance For reliable repair of amalgam restorations, including dentin fractures, the amalgam surface should first be silica coated; dentin/enamel should be etched, washed and rinsed thoroughly. Then, amalgam should be silanized and primer/bonding should be applied onto dentin.

Abstract Aim The aim of this study was to evaluate the bond strength of bonded amalgam to dentin when unfilled and filled adhesive systems are employed using different application modes and to compare the adhesives with a cavity varnish and unlined restorations. Methods and Materials One hundred twenty sound third human molar teeth were used in the study. A cylindrical cavity 3.3 mm in diameter was prepared in a cross section of dentin approximately 3.0 mm in thickness. The specimens were divided into six experimental groups (n=20) according to the cavity liner used in the prepared cylindrical cavity: One Coat Bond™ (O), Scotchbond Multi-Purpose™(S), Panavia 21™ (Pa), PQ1™ (P), Copalite™ (C), and the unlined (U) group which served as the control group. Cavity surfaces were treated with the assigned adhesive/liner according to manufacturer's instructions then restored with amalgam. After storage in saline solution for seven days at 370C, the specimens were subjected to a push-out test at a crosshead speed of 1 mm/min. The mode of failure was assessed by microscopic analysis of the fracture sites. Data were analyzed by analysis of variance (ANOVA) and Duncan Multiple range tests (α=0.05). Results No significant difference in amalgam-dentin bond strength was found among O (23.47 MPa), S (21.02 MPa), and Pa (20.06 MPa) adhesive groups, but there was a significant difference between each of these groups and the P and C groups. The U group exhibited significantly lower retention than the other groups (P<0.05). Conclusion Different bond strengths were observed with the different types of dentin bonding agents and liners employed. The lowest bond strength was seen in the U group. Clinical Significance A statistically significant difference in bond strength was observed with O, S, and Pa compared to P, but this finding is not sufficient to rely on the bonding of amalgam to dentin, particularly in complex amalgam restorations.
