Minimally Invasive Management of Opacities and Enamel Hypoplasia: Case Study.

Developmental enamel defects can negatively affect esthetics and patient satisfaction. Minimally invasive treatments have emerged as alternatives to conventional restorations, but quantitative evaluation of their outcomes is limited. The objective of this case report was to assess the efficacy of a combined minimally invasive approach in improving enamel appearance using objective color and fluorescence measurements. A 23-year-old male patient presented with enamel hypoplasia and opacities on 24 teeth. The treatment protocol included: (1) three weeks of at-home bleaching with 16% carbamide peroxide using a custom tray; (2) micro-abrasion with 6.6% hydrochloric acid and silicon carbide slurry followed by 5% sodium fluoride varnish; and (3) applications of 15% hydrochloric acid etching, drying, and resin infiltration. The patient was advised to use a remineralization agent for one month. Fluorescence measurements and color contact-spectrophotometer readings were recorded at baseline, after each treatment stage, and during six- and 12-month follow-ups. Marked improvements in enamel color and fluorescence were observed after bleaching and resin infiltration, and despite a slight decline over time, values remained superior to initial measurements during follow-ups. This multistage minimally invasive approach achieved substantial improvements in enamel appearance, demonstrating its effectiveness for managing enamel opacities.
