The aim of this study is to validate a near-infrared light transillumination device (DIAGNOcam, KaVo, Biberach, Germany) for interproximal enamel caries detection and compare it with the established diagnostic methods (visual examination and bitewing radiography). The aim is to avoid/reduce ionizing radiation for caries diagnostic purposes.

If the active comparator does not detect cavitation, fluoride varnish is applied on the test surface.
If the active comparator does detect cavitation, a composite restauration is placed
Caries Extension According to Diagnocam Codes 0-4 (Intra- and Interrater-Reliability, Sensitivity and Specificity)
The geometrical shape of caries lesions is displayed with the near infrared transillumination method. These shapes are classified as: code 0: no lesion visible; code 1: first visible signs in enamel; code 2: established, clear visible signs in enamel; code 3: clear visible in enamel and punctual contact with dentine; code 4: clearly visible and broad contact with dentine Intra- and Interrater-Reliability: Reliability indicates the overall consistency of a measurement. To have a high reliability means in this case, that the diagnostic-tool produces similar results under consistent conditions. The interrater-Reability assesses the degree of agreement between two different raters in their diagnostics on a specific test while the intrarater-Reliability assesses the degree of agreement of a single rater who did a diagnostic-test twice under the same testing conditions. Sensitivity and Specificity: Statistics are not done yet but will be updated when we calculated them
