Resin Infiltration Technique – A Microinvasive Treatment Approach for White Spot Lesions

White spot lesions (WSL) are defined as surface and subsurface demineralization of enamel without the formation of a cavity. These lesions have always been an aesthetic concern for patients. There are different treatment options for these lesions. Recently a new micro-invasive technique has been introduced for the treatment of WSL, by infiltrating the lesions with a low-viscosity resin. This technique is simple, painless, and improves aesthetics. This case report explains the ultra-conservative method of treating white spots using resin material ICON. This technique relies on the infiltration concept and helps treat white spot lesions on proximal regions and smooth surfaces.
