• Polymer solutions were prepared by first weighing the designated amount of solvent into a 250ml jar that has a cap. The designated amount of polymer material was then added to the jar. The jar was sealed and then placed on a Wheaton Culture Roller for 2-3 days ( ⁇ 30rpm) until the polymer was completely dissolved in the solvent. Additional ingredients such as NaF, other salts, viscosity modifiers, flavorings, etc. were added to the polymer solution using two 2 minute cycles in a speed mixer (SpeedMixer DAC 150.1 FVZ available from FlacTek, Inc., Landrum, SC) set at 3000rpm. The materials used in each coating composition as well as the amount (in grams) are shown in the examples and tables below.
• compositions of the invention and comparative compositions were coated onto a glass (or plastic if noted) slide (available from VWR, Radnor PA ) or bovine teeth using a cotton swab or small brush.
• the coated substrate what then dipped into a container of tap water for 30 seconds at room temperature ( ⁇ 25°C).
• the coating was then qualitatively evaluated to determine if a film had formed ("set"). Additionally the set films were evaluated at to their adhesion to the substrate. Adhesion was deemed “good” when the set film could not be pushed away by finger pressure and "no" when the set film could be pushed away by finger pressure.
• Abrasion resistance was evaluated by brushing the set coating with a tooth brush and counting the number of brush strokes required to remove the coating.
• Approximately 40-5 Omg of coating composition was evenly painted onto a 1 inch x 1 inch plastic slide (Rinzyl plastic micro slide available from VRW, Radnor, PA).
• the coated slide was immersed in 25ml of deionized water in a plastic test tube for 1 hour. After 1 hour, the slide was removed, rinsed and immersed in a second 25ml aliquot of water in another test tube. After 3 more hours (4 hours total), the process was repeated and the slide was immersed in a third 25ml aliquot of water. After 2 more hours (6 hours total) the process was again repeated and the slide was place in a fourth 25 ml aliquot of water where it remained for an additional 18 hours (24 hours total) before being removed.

• Bovine teeth were potted in a polymethylmethacrylate (PMMA) resin and then polished with 320 grit sandpaper to expose the enamel surface. The exposed enamels were wiped with paper tower to remove excess of water, then coated with about lOmg materials to form a thin layer on enamel, and then stored in 37°C artificial saliva for varying amounts of time.
• a tooth brush machine (available from Foth Production Solution, LLC, Greenbay WI) was used to test coating wear durability on enamel. Tooth brush head was cut from tooth brush with brand name Acclean gentle care from Henry Schein and inserted into the fixture on the tooth brush machine. The potted bovine teeth were inserted and fixed in a plastic port filled with brush media. The tooth brush head was rest on the coating surface. The machine can control the tooth brush head moving back and forth against the coating on enamel. The brushing stroke is defined as brushing the surface back and forth one time. 5ml of 1 : 1 water and tooth paste (CREST cavity protection tooth paste) mixture was used as brush media.

• Coating compositions were prepared and coated as described above using the materials and amounts (in grams) as outlined in Table 4 below. The coated films were evaluated for set, adhesion and fluoride release as described above.
• the pH of the coating compositions outlined in Table 4 was determined using pH paper as described above. Coatings were then prepared as described above by placing about 25mg of coating composition on a 2.5cm x 2.5 cm square glass slide and then dipping the coated slide into tap water for 30 seconds to form a hard film. The coated slides were removed from the tap water and then dipped into 100 ml of water that was adjusted to pH 4 with a trace amount of 37% phosphoric acid. After 10 seconds the coated slides were removed from the acid adjusted water and the pH of the acid adjusted water on the wet coated surface was determined using pH paper. The results of this buffering test are shown in Table 4 below.
• the abrasion resistance on bovine teeth of coating composition of Ex 6 and 7 was determined as described above. Three replicate samples of coated teeth were soaked in 37°C artificial saliva for either 3 hours or 24 hours and then subjected to brushing. The amount of coating removed after a specific number of brush strokes is reported in Table 5 below.
