Uso de infiltrante resinoso (ICON) para tratamento de lesões de mancha branca
Resumo:
Introduction: The Resin Infiltrant (ICON) fills the microporosity of the white spot lesion body, by infiltrating a light-curing low viscosity resin, in order to camouflage white spots, improve aesthetics and prevent the progression of dental caries. Review: Morphological alterations of white spot, both pre-eruptive (fluorosis, amelogenesis imperfecta) and post-eruptive (caries lesion), cause dispersion of incident light rays, due to the difference in the refractive index of hydroxyapatite and of air, which fills the demineralized pores and results in this unsightly optical effect. However, the resinous infiltrant ICON, which through capillary forces is transported in the porosities of the enamel, where it fills the empty spaces, and after its polymerization, blocks the diffusion pathways for cariogenic acids and dissolved minerals, which provides paralysis and alteration of the light scattering by the refractive index (RI) of the resin, resembling the existing healthy enamel, that is, camouflaging the white spot. Discussion: The esthetic function, mimicry of the white spot lesion, pigmentation susceptibility and functional microhardness of the enamel are directly related to the depth and extension of the lesions, considering that its roughness is acceptable. Final considerations: The resinous infiltrate (ICON) camouflages superficial white spot lesions, increases enamel microhardness and paralyzes carious activity.
Keywords: dental enamel, resinous infiltrate, white spot.
