Detecting leftover decay on Class II cavity walls in primary teeth after atraumatic restorative treatment

Detection of Residual Caries on Class II Cavity Walls in Primary Teeth Following Atraumatic Restorative Treatment (ART): A Comparative Evaluation of Fluorescence-Aided Caries Excavation (FACE), Caries Detection Dye, and Clinical Assessment

Not applicable Interventional Çanakkale Onsekiz Mart University · NCT07250022

This tests whether a fluorescence device (FACE), a staining dye, or visual-tactile checks best find leftover decay on cavity walls in children aged 4–9 after atraumatic restorative treatment.

What this trial studies

After ART is performed on asymptomatic multi-surface carious lesions in primary teeth of cooperative children aged 4–9, clinicians will use three methods—FACE, caries detection dye, and visual-tactile examination—to detect residual caries on Class II cavity walls. The study compares diagnostic agreement and effectiveness of these approaches to determine which method most reliably identifies remaining infected dentin while minimizing removal of healthy tissue. Outcomes include concordance between methods and the frequency of detected residual caries, with all procedures performed at a single university dental clinic. Findings are intended to inform clinical choices for confirming complete caries removal during ART.

Who should consider this trial

Good fit: Healthy, cooperative children aged 4–9 with asymptomatic multi-surface carious cavities in primary teeth whose parent/guardian provides written consent and who give assent are ideal candidates.

Not a fit: Children with acute dental infection, systemic health conditions, inability to cooperate, or those without suitable multi-surface carious lesions are unlikely to be eligible or to benefit from the methods tested.

Why it matters

Potential benefit: If successful, this could help dentists more accurately detect and remove leftover decay during ART, reducing repeat treatments and preserving healthy tooth structure in children.

How similar studies have performed: Previous work shows FACE has promise for improving visual detection of caries while caries detection dyes often over-stain demineralized but noninfected dentin, so evidence is mixed but FACE is encouraging.
