Icon - Resin Infiltrations
What Is Icon - Resin Infiltration?
Resin infiltration is a restorative treatment for post-ortho white-spot lesions (WSLs) that is minimally invasive. WSLs are associated with subsurface enamel porosities caused by a cyclical imbalance between demineralization and remineralization of the enamel, resulting from poor hygiene and associated plaque, bacteria and acids. Over time, remineralization at the outer surface of the tooth decreases the access of calcium and other ions to deeper portions of the enamel, eventually arresting the lesion. The lesions look white because there is a scattering of light at the subsurface of the demineralized enamel.
