Effectiveness of Infiltration With Resin in Treatment of MIH Incisors in Children Showing Opacities

Summary

Enamel development defects are the result of a set of environmental, systemic and genetic causal agents that reveal a multifactorial etiology model, which in anterior teeth produces a serious aesthetic problem, converted into a problem of visual perception. In hypomineralized enamel, light rays encounter multiple interfaces between organic and mineral fluids, with different refractive indices. At each interface, the light is deflected and reflected, producing an overexposed "optical labyrinth" that is perceived as a yellow, white, or brown stain.

The term "infiltration" has been modified and developed commercially in Germany for the treatment of non-cavitated caries on smooth and proximal surfaces, in which the porosities of the enamel lesion are infiltrated with a low-viscosity resin, thus creating a barrier of diffusion, without the need for any type of additional material on the tooth surface.

An added positive effect of infiltration with the queens is that the enamel lesions lose their whitish appearance when the microporosities are filled, mimicking the area of the lesion with the remaining healthy enamel. This effect is what has led clinicians to adapt this treatment for the management of enamel defects.

Given the growing interest in the treatment of opacities in the anterior sector, due to the demanding contemporary aesthetic requirements, and the increased acceptance of minimally invasive therapies, the need has been seen to seek greater predictability for the treatment of defects. of conservative enamel from an early age and offer effective therapeutic alternatives.

Interventions

PROCEDURE

white defects

"With the previously cleaned tooth, the enamel will be prepared with a product that makes it more porous, thus eliminating the decalcified areas of the deepest part of the lesion. After completely removing the water from the surface, the resin will be applied infiltrating between the canaliculi of the enamel. When polymerized, it will form a framework that will seal the surface, thus improving surface resistance and aesthetics by modifying the refractive indices of the affected enamel, mimicking it with the remaining healthy enamel".
