Comparative Evaluation of Shear Bond Strength of Orthodontic Metal Bracket Bonded with the Conventional Adhesive System and Moisture Insensitive Primer System on a Tooth Surface Which has Undergone Bleaching with 35% Hydrogen Peroxide - An Study.

Background And Objectives: Today, orthodontic bracket bonding on the tooth surface is a vital phase in any orthodontic therapy as strong tooth-bracket bonding is essential for success and efficiency. Tooth whitening is popular due to tooth discolouration and patient need for esthetic changes. This study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of brackets bonded with a conventional and moisture-insensitive primer system on tooth surfaces bleached with 35% hydrogen peroxide in dry and moisture conditions.
