Early detection of initial caries with fluorescent starch nanoparticles versus salivary biomarkers

Official title: Early Detection of Initial Caries Using Fluorescent Starch Nano-particles Compared With Salivary Biomarkers

Run by Menoufia University · NCT07732127 · Data updated 2026-11-12

This study tests whether fluorescent starch nanoparticles can detect early tooth decay earlier than salivary biomarkers in people with suspected initial enamel caries.

Is this trial a fit for you?

Likely a good fit

Ideal candidates have at least one suspected initial enamel carious lesion and have not had cavitated lesions, restorative treatment on the examined tooth, recent antibiotic therapy, systemic salivary disorders, or xerostomia.

Probably not a fit

Patients with cavitated lesions or conditions that affect saliva may not benefit from this diagnostic approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study aims to see if fluorescent starch nanoparticles can identify early enamel caries that are not yet cavitated. Participants with at least one suspected initial lesion will undergo testing with the fluorescent nanoparticles and analysis of salivary biomarkers. The study compares the nanoparticle method to saliva-based indicators to determine which approach detects early demineralization more reliably. Conventional methods like visual-tactile exams and bitewing radiographs are acknowledged as limited at this stage. The trial is conducted at Menoufia Dental Hospital under the lead sponsorship of Menoufia University.

Why it matters

Potential benefit: If successful, patients may receive earlier and less invasive detection of early caries, enabling timely preventive care.

How similar studies have gone: Prior research in non-invasive biomarkers and saliva-based indicators has shown promise, but this specific nanoparticle fluorescence approach is novel.
