Treatment protocol of dental bleaching and resin infiltration for white spot lesions.

White spot lesions are considered to be a major concern in esthetic dentistry. These lesions can be treated with noninvasive to less invasive procedures, which remain a challenge for many clinicians. The treatment of choice should be as minimally invasive as possible and should aim to minimize the color difference between the white spots and the healthy tooth enamel. Tooth whitening can be used initially to minimize this difference by rendering the extent of the white spot defects less visible, which permits a bevel effect. In addition, the microinvasive treatment option of resin infiltration, which does not involve trauma or require cavity preparation, can supplement the tooth whitening procedure to achieve excellent esthetic results, giving patients renewed confidence in their smiles. Therefore, the purpose of the present study was to illustrate the combination of dental bleaching and resin infiltration in a patient with white spot lesions caused by diffuse opacities (teeth that were undergoing enamel maturation at the time of occurrence of a systemic insult). The treatment aimed to improve the patient's esthetics, self-esteem, and quality of life.
