Association between bleaching techniques for the treatment of teeth with chromatic alteration - Case report

Dental trauma is one of the most common causes of post-eruptive intrinsic color changes in teeth. The dissatisfaction with smile aesthetics is one of the main motivators for seeking dental procedures such as tooth bleaching, which stands out for being a little-invasive procedure with immediate and satisfactory aesthetic results. The objective of this paper is to describe a case report of a 24-year-old patient who attended the Postgraduate Program in Dental Clinic Practice at the Piracicaba Dental School – University of Campinas, which involved as main complaint tooth darkening after trauma in childhood. Internal bleaching of a dental element was performed using sodium perborate and distilled water associated with in office external bleaching with 37% hydrogen peroxide to provide a more harmonious smile to the patient. The association of bleaching techniques is an alternative widely indicated and effective in cases where it is desirable to maintain the integrity of dental elements, especially in young patients, avoiding more invasive restorative procedures and resulting in patient satisfaction.
