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.
Participants aged 11 to 46 years
Completed fixed orthodontic treatment
Presence of at least four active non-cavitated caries lesions (ICDAS 1-3)
Lesions located on vestibular surfaces of anterior teeth and/or premolars
Systemic conditions affecting salivary flow or enamel structure
Extensive cavitated lesions requiring restorative treatment
Ongoing orthodontic treatment
Use of medications that significantly affect oral conditions
The study population will include post-orthodontic patients from Bogotá, Colombia, aged 11 to 46 years, presenting active non-cavitated caries lesions on vestibular tooth surfaces. Participants will be recruited from university clinical settings and enrolled in a preventive follow-up program involving clinical and digital caries assessment methods.
