The aim of this study was to test the influence of toothpaste and prophylaxis paste remnants as well as powder remnants on DIAGNOdent readings. A total of 68 sites on the occlusal surface of human molars were used for this study. After a cleaning procedure, saliva was spread on the tooth surface, dried for 3 s, and DIAGNOdent (DD) values were measured. After these measurements were performed, 500 mg of the toothpaste or prophylaxis paste was taken and the occlusal surface was cleaned for 3 s with a slow rotating contra‐angle handpiece. The paste was then rinsed off with the 3‐in‐1 syringe for 3 s using water with air. The DD measurements were taken again and the rinsing for 3 s and fluorescence measurements were repeated. The procedure with the powder using the PROPHYflex 2 was, in principle, the same. Whereas only small differences could be detected on sound surfaces, there was a distinct influence on decayed surfaces. It could be concluded that when the DIAGNOdent device is used in practice and special care in rinsing after cleaning is not taken, it is possible that false readings are registered.
