WHAT IS ICON? Resin infiltration is a minimally invasive restorative treatment for post-ortho white-spot lesions (WSLs) and certain congenital hypocalcified enamel lesions (“hypo” spots). 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. With time, reminerlization 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. Hypo spots, or enamel bruising, are congenital enamel defects often caused by trauma or infection involving the primary teeth.
