Brief Summary
This clinical study aims to compare the remineralizing effects of self-assembling peptide P11-4 (SAP11-4) with fluoride varnish in the treatment of post-orthodontic non-cavitated carious lesions (NCLs). The study uses the QLF camera to assess changes in lesion size, severity, and mineralization, evaluating the effectiveness of SAP11-4 in comparison to fluoride varnish or no treatment. The primary endpoint is the change in QLF parameters, alongside ICDAS scores and Nyvad criteria for clinical evaluation.

Eligibility Criteria
You may qualify if:
- \- Patients (18-30 y old) with ≥ 20 permanent teeth were included in the study.
- Presence of non-cavitated accessible carious enamel lesions on the vestibular surfaces (ICDAS II codes 1 and 2) after debonding of the fixed orthodontic appliances that do not require invasive treatment.
- The patients completed the fixed orthodontic therapy within the past 2 weeks \[48\].
- No professional topical fluoride application during the last 6 months prior the study.
- Patients are able and voluntarily attend the study visits and have a proper oral hygiene during the study.
- A written informed consent was signed before the start of the study.
- Female patients declare no pregnancy and breast feeding.
- Stimulated salivary flow rate ≥ 1 ml/min.
- The patients have lived in the same geographic region with constant fluoride concentration in the water during the last five years.
You may not qualify if:
- \- Previously treated NCLs.
- Teeth with carious lesions placed apart from the fixed orthodontic appliances.
- Presence of restorations in contact with the carious lesion.
- Previous application of remineralizing agent \<6 months prior to study treatment.
- Evidence of tooth erosion.
- Patients with dental fluorosis, enamel hypoplasia or tetracycline pigmentation.
- Present health conditions like diabetes, history of head and neck illnesses, metabolic disorders affecting bone turnover.
- Immunosuppression drugs.
- Pregnant and breast-feeding women.
- Significantly reduced salivation (unstimulated/stimulated); concomitant medication intake, affecting salivary flow.
- Concurrent participation in another clinical trial.
