title: Shear Bond Strength of Three Orthodontic Bonding Systems on Enamel and Restorative Materials.
abstract: Objective.The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of two self-etching no-mix adhesives (iBond™and Scotchbond™) on different prosthetic surfaces and enamel, in comparison with the commonly used total etch system Transbond XT™.Materials and Methods. A total of 270 surfaces (1 enamel and 8 restorative surfaces,n= 30) were randomly divided into three adhesive groups. In group 1 (control) brackets were bonded with Transbond XT primer. In the experimental groups iBond adhesive (group 2) and Scotchbond Universal adhesive (group 3) were used. The SBS was measured using a Zwicki 1120™testing machine. The ARI and SBS were compared statistically using the Kruskal-Wallis test (P≤ 0.05).Results. Significant differences in SBS and ARI were found between the control group and experimental groups.Conclusions. Transbond XT showed the highest SBS on human enamel. Scotchbond Universal on average provides the best bonding on all other types of surface (metal, composite, and porcelain), with no need for additional primers. It might therefore be helpful for simplifying bonding in orthodontic procedures on restorative materials in patients. If metal brackets have to be bonded to a metal surface, the use of a dual-curing resin is recommended.
