Summary

Obtaining good adhesion between enamel and bracket is a fundamental aspect for success in Orthodontics. Some cases present challenges in this adhesion, especially when we are faced with enamel with alterations such as hypomineralization, hypoplasia or dental fluorosis. To overcome this difficulty in adhesive bonding, various therapeutic strategies have been proposed, such as the use of deproteinizing agents. The objective of this study is to describe the use of sodium hypochlorite as a deproteinizing agent in teeth with enamel alterations to improve adhesion in Orthodontics. A bibliographic search was carried out in PubMed for articles within the last 5 years. In this study 116 articles were found, of which 23 met the required criteria and were selected for the review. Deproteinization of the enamel with sodium hypochlorite as a prior step to acid etching is an important stage in the cementation process of fixed appliances in orthodontics. The use of 5.25% sodium hypochlorite is a low-cost, non-invasive and efficient alternative to improve adhesion strength in patients with anomalies of tooth enamel.

KEY WORDS: orthodontics, enamel deproteinization, hypochlorite, dental fluorosis, bracket failure, adhesive.
