A Randomized Split-Mouth Clinical Trial Comparing Resin Infiltration and Microabrasion for Early Caries Lesions

Resumen breve

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.
