- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: PHASE2/PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Subjects were to have at least three caries proximal lesions on their posterior permanent teeth with a radiographic severity classification of the lesion score of 3 -Around the enamel dentin junction (EDJ) or 4 -Dentin-outer 1/3.~Exclusion Criteria:~* Under orthodontic treatment at enrollment~* Moving from the city (Bogota) in the following three years after commencing the study.

Study Arms:
- Treatment with Infiltrant/Adhesive (Type: EXPERIMENTAL): In this split-mouth design study, one of the three randomly selected approximal lesions will be treated with an infiltrant resin, one will be treated with an adhesive resin.
- Placebo, placebo treatment (Type: PLACEBO_COMPARATOR): In this split-mouth design study, one of the three randomly selected approximal lesions will be treated with a placebo treatment: At baseline one caries lesion was cleaned with a microbrush for 30 seconds and the procedure was repeated after two minutes.

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