NCT06749977

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.

Outcome Measures

Primary Outcomes (3)

  • QLF measuerement of the lesion's depth

    The depth of the lesion (parameter deltaF) was monitored throughout the study period.

    Day 0, Day 120, Day 360

  • QLF measurement of the lesion's volume

    The volume of the white spot lesion (parameter deltaQ) was monitored throughout the study period.

    Day 0, Day 120, Day 360

  • QLF measurement of the lesion's Area

    The size of the white spot lesion (parameter Area) was monitored throughout the study period.

    Day 0, Day 120, Day 360

Secondary Outcomes (2)

  • International Caries Detection and Assessment System (ICDAS) score changes

    Day 0, Day 120, Day 360

  • Caries activity assesment

Eligibility Criteria

Age18 Years - 30 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

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.
