Methods: Polished human enamel samples were exposed to fluoride varnishes: Bifluorid10 ® (NaF&CaF 2-45200 ppmF), Duraphat ® (NaF 22600 ppmF), Fluor-Protector ® (difluorsilane 1000 ppmF) and a control coating of copal ether varnish (0 ppmF) group and a deionized water group. For each group of 16 samples, nine cycles of erosion and nine cycles of erosion-abrasion [1 cycle = erosion (0.3% citric acid, pH 3.2, 5 min) + artificial saliva (1 h, pH 7.0) + abrasion (120 linear strokes in artificial saliva from Oral B medium soft brushes 300 g loading]. The change in the enamel surface was evaluated using optical profilometry. Results: Duraphat ® and Bifluorid10 ® applications had a median (IQR) step height of 4.21 um (1.59) and 5.01 um (1.02). This was statistically significantly less than Fluor-Protector ® 6.83 um (1.25), copal ether 7.22 um (1.97) and water 7.39 um (1.96) (p < 0.001). For erosion-abrasion, both Duraphat ® and Bifluorid ® had statistically lower step heights than the other products (p < 0.01). Conclusions: The action of fluoride in a range of single-application topical varnishes was effective in reducing enamel wear from erosion and erosion-abrasion in this laboratory study.

To our knowledge, this is the first case report showing maxillary midline diastema closure after implant placement.
