Abstract

Resin infiltration is a minimally invasive technique that has emerged almost 10 years ago. One of its major applications is the masking of initial carious lesions also known as white spot lesions (WSL). Resin infiltration has also shown considerable success in masking of WSL of developmental origin such as fluorosis and molar-incisor hypomineralization. Due its immediate action and superior esthetic results, resin infiltration has become an alternative to other treatment options for WSL such as remineralization and micro-abrasion. However, color restorability of resin infiltration is affected by a number of factors including lesion depth, number of etching cycles and infiltrant duration and application time. Therefore, for successful masking of WSL, these factors must be known and considered before application of resin infiltrant. In addition, due to the infiltrant composition, resin-infiltrated teeth are prone to discoloration if subjected to colored foods and drinks. Long-term color stability is essential for superior esthetic outcome and patient satisfaction. Therefore, to achieve the best possible results, the technique of resin infiltration and factors affecting the esthetic outcome will be discussed.
