The erosion/infiltration technique made by a polymer based on TEGDMA to mask the white lesions of the tooth

It is common to observe anterior teeth that present white opacities of enamel in relation to hypomineralization. These lesions alter social life of children and adults. There is a recent non-invasive treatment that can remove these stains without loss of substance, keeping tooth structure intact. This treatment modifies the optical properties of the white spot by infiltrating a polymer based on trimethylene glycol dimethacrylate (TEGDMA). This short article presents a method called erosion/ infiltration, which our team first described. Dentists must be aware of it, in order to treat patients with either fluorosis, MIH or trauma, so that much more invasive treatments such as veneers and crown can be avoided.
