Treatment of White Spot Lesions by Resin Infiltration

Aim: To review the scientific principles of the treatment of white spot lesions with the resin infiltration technique and to discuss its application and limitations.
Methodology: A PubMed database research was conducted and limited to articles published in English between the years of 2008 and 2013. Twenty-six articles were selected out of 48.
Discussion: The resin infiltration procedure is a promising minimally invasive dentistry technique. Resin infiltration produces a positive effect on aesthetics, preserves tooth structure, delays or even eliminates the need for a restorative treatment and eliminates the risk of post-operative sensitivity and pulp inflammation. Although it has recently been developed, the results are very satisfactory. However, investigation is still needed (particularly with longer follow-ups and larger samples) as well as the development of specific and simplified protocols.
