Caries infiltration with resins: a novel treatment option for interproximal caries

Noninvasive (preventive) measures involving fluoridation, dietary control, and oral hygiene instruction, as well as invasive restorative methods, are the standard treatment options for interproximal caries. Intermediate treatment options, similar to pit-and-fissure sealing on occlusal surfaces that has been shown to be effective in preventing and inhibiting caries, have not yet been established on interproximal surfaces. Recently, the application of resins on interproximal caries lesions has been studied and improved, leading to the development of new materials, which infiltrate and seal the carious lesion, improving the inhibition of caries progression. Clinical data show this new technique complements existing treatment options for interproximal caries by delaying the time point for a restoration and consequently closing the gap between noninvasive and invasive treatment options.
