Objective:
This report aims to present a clinical case demonstrating the use of resin infiltration for the esthetic improvement of enamel defects in primary incisors.
Clinical Considerations:
A 3-year-old girl presented with demarcated opacities and post-eruptive breakdown on primary incisors. This condition was associated with dental hypersensitivity and psychosocial discomfort due to tooth discoloration. A micro-invasive approach was planned to preserve tooth structure. Under rubber dam isolation, the lesions were etched (15% HCl) and dried. Resin infiltration was performed and monitored via transillumination to ensure deep penetration. The resin infiltration step, which lasted approximately 17 min, was interrupted due to patient behavior; nevertheless, there was a clinically acceptable esthetic improvement in the opacities and relief of hypersensitivity.
Conclusions:
Resin infiltration showed potential immediate esthetic enhancement and functional relief from hypersensitivity in primary incisors. Further longitudinal studies are essential to assess the long-term stability of these outcomes in the primary dentition.
