Exclusion Criteria: * Children with systemic diseases or developmental dental anomalies that could affect hypomineralization. * To have MIH outside the specified scores. * Children unable to continue treatment in the chair due to cooperation problems. * Failure to attend control sessions or a desire not to continue with the study. * Patients and their parents unwilling to participate in the treatment. * If the patient cannot attend control sessions or disrupts sessions, they will be withdrawn from the study.
