QLF and Digital Imaging for Caries Activity Assessment After Orthodontic Treatment
20. maj 2026 opdateret af: Andrea Cortes, Universidad El Bosque, Bogotá
Diagnostic Performance of Smartphone, 3D Imaging, QLF-D, and ICDAS Clinical Criteria for Non-Cavitated Caries Activity Assessment in Post-Orthodontic Patients Under a Preventive Program
This prospective longitudinal observational study aims to evaluate the diagnostic performance and agreement of Smartphone photography, intraoral 3D imaging, Quantitative Light-Induced Fluorescence Digital (QLF-D), and ICDAS clinical criteria for assessing non-cavitated caries lesion activity in post-orthodontic patients under a preventive follow-up program.
Thirty participants aged 11 to 46 years with active initial caries lesions will be followed for three months.
Clinical examinations, QLF-D imaging, smartphone photographs, and intraoral 3D scans will be obtained at baseline and follow-up visits combined with professional prophylaxis and oral hygiene reinforcement.
The study will analyze changes in lesion activity, fluorescence parameters, and surface characteristics over time, as well as the agreement and diagnostic performance among the evaluated methods.

Detaljeret beskrivelse
This prospective longitudinal observational study will evaluate the agreement and diagnostic performance of Smartphone photography, intraoral 3D imaging, Quantitative Light-Induced Fluorescence Digital (QLF-D), and ICDAS clinical criteria for assessing non-cavitated caries lesion activity in post-orthodontic patients.
Participants presenting active initial caries lesions on vestibular tooth surfaces will undergo clinical examinations, QLF-D imaging, smartphone photographs, and intraoral 3D scans at baseline and during a three-month preventive follow-up program. Professional prophylaxis and oral hygiene reinforcement will be performed throughout the study period.
Changes in clinical lesion activity, fluorescence parameters, and topographic characteristics will be analyzed to determine the monitoring capacity, agreement, and diagnostic performance of the evaluated methods. Patient acceptance of the diagnostic technologies will also be assessed.

Post-Orthodontic Patients With Non-Cavitated Caries Lesions
Participants aged 11 to 46 years who have completed fixed orthodontic treatment and present at least four active non-cavitated caries lesions (ICDAS 1-3) on vestibular surfaces of anterior teeth or premolars.
Participants will undergo clinical assessment using ICDAS criteria, QLF-D imaging, smartphone photography, and intraoral 3D scanning during a three-month preventive follow-up program that includes professional prophylaxis and oral hygiene reinforcement.
