Abstract

It is generally not recommended that bonded restoration treatment should be carried out immediately after bleaching treatment. However, the use of antioxidants such as sodium ascorbate can be useful to avoid a waiting period. This article is a brief review about in vitro proposals to overcome low bond strength values to bleached dental surfaces. It shows a one-year follow-up case report of a young female presenting agenesis of maxillary lateral incisors reshaped with direct resin composite immediately after dental bleaching. Teeth were bleached with a combination of in-office and at-home whitening protocols, followed by the application of a 10% sodium ascorbate gel for one hour, to allow the immediate reshaping with direct resin composite restoration. After one year, the clinical performance of the restoration was successful. The use of sodium ascorbate gel can help the clinician to perform bonding procedures immediately after bleaching treatments.
