RESIN INFILTRATION FOR THE MANAGEMENT OF ENAMEL OPACITY - A CASE SERIES AND LITERATURE REVIEW Resin infiltration (RI) technique was introduced as one of the minimally invasive dentistry techniques for the management of enamel opacity. Six young patients with post-orthodontic white spot lesions, molar incisor hypomineralization, fluorosis, and amelogenesis imperfecta were treated with resin infiltration (RI). RI was used alone or in conjunction with bleaching or microabrasion. The esthetic improvement of lesions is immediately noticeable following treatment, even though some enamel discoloration remained visible. No color changes of the treated teeth noted after 6-month review. The use of RI alone or in combination with the other interventions has been shown to be successfully masking enamel opacities in young patients. Therefore, RI technique can be an option in managing enamel opacity of anterior teeth due to demineralization or developmental defects of enamel.
