White spot lesions: Resin infiltration technique

Nowadays, dentists are facing increased aesthetic demands from patients. Corrections of shade, shape, texture and position are the most requested. The shade of the teeth is a very important concern for patients, especially when white spots cover a big part of their front teeth. On the other hand, all of the focus in the last fewyears has been to create more conservative techniques to solve this problem. Erosion/infiltration protocol using Icon (DMG, Hamburg, Germany) is one of the most conservative and efficient protocols. The Icon treatment was initially proposed as a simple and minimally invasive alternative for caries treatment of initial proximal lesions, but surprisingly the technique proved a high ability to mask the white spots by modifying the refractive index of the lesion. The aim of this article isto describe this technique in detail using a clinical case.
