Background: - To evaluate and compare the effects of Silver diamine fluoride (commercial and lab prepared) versus nano silver fluoride on demineralized human enamel surfaces. Materials and methods: - A total 20 Extracted premolars for orthodontic reasons were collected from the Outpatient Clinic of surgical Department, Faculty of Dentistry, Suez Canal University. Each premolar was sectioned buccolingually into two halves, to obtain (40) specimens. These halves were randomly allocated into 5 groups according to different treatment modalities. Group I included 8 specimens were left untreated (negative control), Group II included 8 specimens were treated with demineralizing solution, Group III included 8 specimens were treated by Silver diamine fluoride (commercial form) after demineralizing solution, Group IV included 8 specimens were treated with Silver diamine fluoride (lab prepared) after demineralizing solution and Group V included 8 specimens that were treated with Nano silver fluoride after demineralizing solution. Each half was evaluated by Environmental scanning electron microscope and Energy dispersive x-ray spectroscopy .Results: There were significant differences between groups at P-value (≤0.05) for Phosphrous, Calcium and Calcium/Phosphrous ratio except (Fluoide). The lowest value for elements was recorded in group (II) followed by control group and the highest value was recorded at group (V).Conclusion: Silver Diamine Fluoride (lab made) is as efficient as commercial one in remineralizing demineralized enamel surfaces. Nano Silver Fluoride is more efficient than Silver Diamine Fluoride (lab made u0026 commercial) on demineralized enamel surfaces.
