- Resin infiltration (Type: EXPERIMENTAL): One proximal caries lesion (split mouth design) per patient will be treated using the resin infiltrant Icon (DMG, Hamburg, Germany) according to manufactures´ instructions.
- Mock treatment (Type: SHAM_COMPARATOR): A second proximal caries lesion of each patient (split mouth design) will receive a placebo treatment to mimic resin infiltration.

Based on this trial design, predict the completion outcome and termination type (if applicable).
