Aesthetics, Antioxidants, Tooth bleaching


OBJECTIVE: Tooth bleeching is a routine intervention in dental office, to be effective in removing stains and browning that compromise the aesthetics of smile. Sometimes there is a need of complementing with composite restorations, but for the use of these requires a certain waiting time. Thus, use of antioxidants such as sodium ascorbate increases the bond strength values due to removal of residual oxygen hinder polymerization. This study examined the use of sodium ascorbate as measure to allow for immediate adhesive restorations after bleaching procedures in vital teeth.
METHODS: For that, they consulted national and international studies published between 1973 and 2015 available in Scielo, VHL and PubMed platforms.
CONCLUSION: It can be concluded that sodium ascorbate has clinical relevance, but its use should be performed with caution, necessitating further investigation. The fact that in some studies its application introduced effective can not be attributed to factors inherent in the methodology.
