2022 AAO Annual Session - Deproteinization of Tooth Enamel Surfaces to Prevent White Spot Lesions & Bracket Bond Failure: A Revolution in Orthodontic Bonding

‐ May 24, 2022 9:15am

Credits: None available.

Orthodontic treatment success is jeopardized by the risk of development of white spot lesions (WSLs) around orthodontic brackets. Unfortunately, the formation of WSLs still remains a common complication during treatment in patients with poor oral hygiene. Nearly 75% of orthodontic patients are reported to develop enamel decalcification because of prolonged plaque retention around brackets. It is the orthodontist’s responsibility to minimize the risk of patients having enamel decalcifications as a consequence of orthodontic treatment. This can be achieved by using hybrid, fluoride-releasing, glass ionomer cement to bond brackets, with deproteinization of the enamel surface prior to phosphoric acid etching.

Learning Objectives:

  • De-proteinize the enamel surface.
  • Bond brackets with hybrid glass ionomer cement.
  • Protect tooth enamel against white spot lesions when brackets are bonded with hybrid, fluoride-releasing, glass ionomer cement.
