Brief Summary:
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.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Active Comparator: Near infrared transillumination
Near infrared transillumination is applied for initial enamel caries lesion detection.
 Other: Non invasive caries treatment
If the active comparator does not detect cavitation, fluoride varnish is applied on the test surface.
Other Name: Fluoridation

Other: Invasive caries treatment
If the active comparator does detect cavitation, a composite restauration is placed
Other Name: Filling

Device: Near-infrared light transillumination device (DIAGNOcam, KaVo, Biberach, Germany)
Active Comparator: Visual caries detection + BW
visual caries detection + bite wing radiography (BW): considered as gold standard in caries diagnostics.
 Other: Non invasive caries treatment
If the active comparator does not detect cavitation, fluoride varnish is applied on the test surface.
Other Name: Fluoridation

Other: Invasive caries treatment
If the active comparator does detect cavitation, a composite restauration is placed
Other Name: Filling

Other: Visual examination and bitewing (BW) radiography

Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Caries Extension According to Diagnocam Codes 0-4 (Intra- and Interrater-Reliability, Sensitivity and Specificity) [ Time Frame: One year ]

    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



Secondary Outcome Measures :
  1. Lesion Activity [ Time Frame: One year ]
    active lesions: 1; inactive lesions: 0
