To evaluate the antibacterial properties of silver diamine fluoride-based remineralizing agents and their effect on the chemical structure of enamel.

Materials and methods

Forty-two sound human mandibular molars were disinfected, coated with nail varnish, leaving a 4×4 mm window on the buccal surface, and dipped in EDTA solution at 37°C for 13 h. The molars were sectioned mesiodistally through the centre to obtain specimens with untreated and test-treated sides. Then, SDF and Riva Star treatment solutions were applied to the test-treated side. Teeth were equally divided according to the test (n=21) and then subdivided into control, SDF, and Riva Star groups (n=7). The antibacterial test was measured by colony-forming units (CFU/ml count). Moreover, the effects of the remineralizing agents on the chemical structure of enamel were evaluated using energy-dispersive X-ray (EDX) elemental analysis.


Concerning the antibacterial test, both SDF and Riva Star materials had a significant CFU/ml mean value (P


Silver diamine fluoride had striking and tangible antibacterial properties and remineralizing effects on the enamel structure.
