White Spot Lesion…
This patient presented with a white spot lesion on the upper left central incisor and was looking for the most conservative treatment option possible.
After discussing the available options, we decided to start with ICON resin infiltration. I explained that while ICON can achieve excellent results, the outcome is never guaranteed and composite bonding may still be required if the lesion remains visible.
The treatment involved six applications of the ICON etching gel and six drying cycles before we achieved the level of improvement shown here. As you can see from the step-by-step images, patience and careful assessment throughout the procedure were key to reaching the final result.
The best part? We were able to achieve a significant improvement without removing healthy tooth structure and without the need for composite bonding.
The final transillumination images are particularly interesting. Before treatment, the lesion can clearly be seen within the enamel. Following resin infiltration, the lesion is no longer visually apparent, demonstrating how effectively the refractive properties of the enamel have been restored.
A great example of how minimally invasive dentistry can deliver excellent aesthetic outcomes while preserving natural tooth tissue.
