Resin infiltration applications in white spot lesions with caries cavities

Abstract

White spot lesions (WSLs) describe the initial stage of caries and appear more opaque and white than normal enamel due to changes in the refractive index of light compared to the normal enamel structure. This condition can cause aesthetic concerns for the patient. The primary cause of its formation is poor oral hygiene and excessive plaque accumulation. In the approach to treatment, significant innovations have occurred over time, and the principle of preserving the tooth structure as much as possible has been adopted instead of removing dental tissue and make restoration. The resin infiltration (RI) technique is believed to reduce the amount of dental tissue that needs to be removed in the treatment of WSLs with cavitated carious lesions while meeting the patient’s aesthetic expectations. This present case report describes the application and follow-up of the RI technique in pediatric patients with cavitated carious lesions adjacent to WSLs in maxillary anterior teeth. Following RI treatment according to the recommendations of the manufacturer, composite restoration was applied to the teeth deemed necessary for restoration, in two male patients aged 14 and 8, who presented with caries cavities.
