White spot formation under orthodontic bands cemented with glass ionomer with or without Fluor Protector.
The purpose of this study was to determine whether an additional application of Fluor Protector before band cementation with glass ionomer cement reduces white spot formation compared with band cementation with glass ionomer cement. In the in vitro study, 80 premolars were divided in half, creating a control and a test group. All specimens were divided into four different groups to simulate different clinical situations and stored in a demineralizing solution to induce white spot formation. In the in vivo investigation, 18 orthodontic patients were incorporated in the study. One lower and one upper first molar band (randomly selected) were coated with Fluor Protector and then cemented with a glass ionomer cement (test group). The other two uncoated first molars were cemented with glass ionomer cement and served as the control group. The application of Fluor Protector in combination with Aquacem did not contribute to a reduction of white spot formation underneath molar bands compared with the use of Aquacem for banding.
