Definitions

• Silver and fluoride ions are well-known for treating tooth surfaces to address hypersensitivity and arrest dental caries.
• Fluoride treatment involves the application of fluoride to a tooth surface with the formation of fluorapatite and calcium fluoride. There are two major in-office fluoride treatment methods currently in use.
• One treatment method uses a fluoride gel/foam in a tray. This method requires several grams of fluoride gel stored in a tray that is then placed into a patient’s mouth onto the teeth. This tray is left in the mouth with the gel/foam in contact with the teeth for 1 to 4 minutes.
• the gel/foam formulation is an aqueous system that includes 2% sodium fluoride. This material requires the use of suction to pull the extra gel out of the mouth to avoid unnecessary high amounts of fluoride ingestion.
• Another treatment method is a dental fluoride varnish.
• Most fluoride varnishes on the market are rosin/ethanol based formulations with a hydrophobic nature. The varnish is painted on the teeth and remains in place for several hours to allow for the fluoride to be released from the composition.
• dentists use fluoride varnishes for in-office fluoride treatment.
• Most dental fluoride varnishes include 5% sodium fluoride. The dose of varnish is about 0.5 gram.
• Dental varnishes place much smaller amounts of fluoride into a patient’s mouth compared to fluoride gel/foams. Thus, fluoride ingestion is less with fluoride varnishes.
• fluoride varnishes are easier to apply as they are simply painted on a patient’s teeth; however, fluoride varnish treatments are more labor intensive than gel treatments and fluoride varnish treatments leave the patient with an unpleasant “dirty teeth” feeling.
• Stable aqueous solutions containing both silver and fluoride ions are needed.
• One such solution includes silver diamine fluoride (SDF); however, SDF is also known for turning the tooth surface black when it is exposed to light.
• SDF silver diamine fluoride
• compositions that are as simple to apply to teeth as varnishes and work in time periods as short as gel/foam formulations are desired, particularly those compositions that include silver and fluoride, but do not stain the tooth surface upon exposure to light.

• methods of treating e.g., methods of providing fluoride to a patient’s tooth surface.
• Such compositions are one-part compositions.
• compositions can be used as in-office oral care solutions (e.g., as fluoride treatment solutions). They can be formulated into a solution that can be painted on a tooth surface if desired. They can provide similar fluoride efficacy to that of varnishes in the shorter periods of time of gel/foam formulations.

• 1 mL of Example 6 solution was placed in a plastic test tube, which was sealed in a glass vial to prevent evaporation.
• the samples were stored for several months under the temperature conditions described below and tested periodically at designated time points.
• Each sample was tested for General Appearance, Precipitation with KH2PO4, and Color Change (Black staining). Additional select samples were also tested for fluoride content over time.
• a precipitation test was performed by inducing precipitation by the introduction of one drop of 1% monopotassium phosphate (KH2PO4) and observing any formed precipitate.
• KH2PO4 monopotassium phosphate
• Color change was performed by exposing the precipitate formed with the addition of KH2PO4 to blue LED light using 3M ELIPAR DEEPCURE-S LED curing light, with wavelength around 450 nm and output approximately 1500 mW/cm2 for 20 seconds. This test was performed to look for dark (e.g., black, brown, or grey) discoloration of the formed precipitate, which is characteristic of the discoloration of silver diamine fluoride + KH2PO4 precipitate when exposed to light.
• dark e.g., black, brown, or grey
• TISAB III Total Ionic Strength Adjustment Buffer III concentrate solution is for use with fluoride ion selective electrodes and is available from Sigma Aldrich.
• the fluoride ion selective electrode was placed in the titrator cup of diluted TISAB III solution and allowed to equilibrate for 30 seconds before analyzing each sample. The fluoride content in ppm was calculated against the fluoride standards calibration curve.
