This study aims to evaluate and compare the clinical characteristics and treatment outcomes of early caries lesions using resin infiltration (Icon) and microabrasion (Opalustre). Early enamel lesions (ICDAS codes 1-2) often present as white spot lesions, which can compromise esthetics and may progress if untreated. This randomized split-mouth clinical trial will be conducted in patients presenting with at least two affected anterior teeth. Each patient will receive both interventions in different teeth, allowing direct intra-individual comparison. Outcomes will be assessed immediately after treatment and at 6 months to determine effectiveness in lesion improvement, esthetic appearance, and patient-related responses. The findings aim to provide evidence for minimally invasive management of early caries lesions.
