Interventions

The dentists were randomly assigned to one of two groups
each group had two dentists. Both groups of dentists examined the same patients (n=140) using the Nyvad and the ICDAS II criteria in different sequences. The first group used the Nyvad criteria during
the second group used the ICDAS II criteria during period 1, followed by Nyvad criteria during period 2. It was a one week washout period between period 1 and period 2 examinations. Before the first p

Design outcomes

Primary

MeasureTime frame
Number of surfaces per individual requiring operative or non-operative treatment measured at the same time twice: in period 1 of examination and in a one week in period 2 of examination

Secondary

MeasureTime frame
Diagnostic outcomes: 1. Nyvad D and ICDAS II D components reflecting activity of the lesions (active non-cavitated lesions, active cavitated lesions, inactive non-cavitated lesions, inactive cavitated lesions). 2. Nyvad D and ICDAS II D (decay) components reflecting activity and depth of the lesions 3. Caries experience of carious lesions (mean DMFS) generated from the Nyvad and the ICDAS II systems
