Consistent with societal trends, there has been a greater emphasis placed on esthetics in dentistry in recent years. This has perpetuated a rapid evolution of dental products to include adhesives and ceramics. The demand for esthetics has also lead to a greater number of adults seeking orthodontic treatment. Those esthetically driven adults are likely to have a dentition more heavily restored with ceramic restorations, as compared to the traditional adolescent orthodontic patients. Ceramics present a challenge when bonding orthodontic appliances so many adhesive protocols advocate the use of hydrofluoric acid etching to achieve adequate bond strength. The purpose of this study was to compare the shear bond strength to etched versus un-etched e.max.
