Adhesives in dentistry and especially orthodontics, provide the necessary retention of restorative materials or appliances to tooth structure. Bonding in orthodontic mainly involves Bis-GMA/TEGDMA-based polymers, applied on acid-treated enamel to provide micromechanical retention. Bond strength, monomer release and degree of cure of the polymeric adhesive are the variables, which modulate the clinical success and biological properties of the materials.

A significant portion of papers focused on the interfacial properties of the enamel-adhesive-bracket interface uder different loading conditions, enamel preparations and wetting conditions. Moisture-insensitive and water-activated adhesives have also been studied and the mechanics of bond strength experiments were analyzed.
