An In-vitro Comparison of the Shear Bond Strength of Three Different Composite Materials with Three Different Etchants for the Bonding of Orthodontic Brackets.

Introduction Esthetics, being the major concern of today's treatments, has led to numerous innovations, including composites, for different treatment options. Esthetic orthodontics requires the use of composites for bonding orthodontic brackets to the teeth. Aims To identify which combination of composites has the highest shear bond strength at the tooth-bracket interface.
