SANT'ANNA, Giselle Rodrigues de et al. Resin infiltration vs microabrasion in white-spot lesions treatment: case report. Rev. Assoc. Paul. Cir. Dent. [online]. 2016, vol.70, n.2, pp. 187-197. ISSN 0004-5276.

Objective: To present a case report of aesthetic treatment of post orthodontic white- -spot lesions in the anterior superior teeth through two minimally invasive techniques using resin infiltration system or microabrasion. Case report: Patient 17 years of age had inactive white-spots lesions on teeth 11, 12, 13, 21, 22, 23. The teeth 11, 12, 13 received the resin infiltrating system Icon® (DMG, Hamburg, Germany) while the teeth 21, 22, 23 were submitted to microabrasion with Whiteness RM (FGM, Joinville, Santa Catarina, Brazil). Both protocols were used according to manufacturer's recommendations. In the teeth 21 and 22, the product of the microabrasion was applied with a spatula that accompanied the kit, while the tooth 23 received the same product applied with a rubber cup at low speed turbine, all by a single operator. The microabrasion with rubber cup occasioned a more smooth and homogeneous surface. Both products had satisfactory results in aesthetic resolution of the white-spots lesions, for a 1-year follow-up. Conclusion: Although both products are able to resolve aesthetic problems of inactive white- -spots lesions, it should be taken into account the clinical time, toxicity, the activity of the lesion and the possibility of wear of the tooth structure.
