Enamel Repair Visualization and Quantification

A method for analyzing, visualizing, and/or quantifying, the repair of damaged tooth enamel resulting from the treatment of the damaged tooth enamel with a test composition, wherein the method comprises the steps of:

• (a) providing a sample of human or animal tooth or enamel have a flat or substantially flat upper surface of enamel;
• (b) covering a portion of the sample surface with an impermeable, removable coating (e.g., half of the sample surface), e.g., as a negative control;
• (c) treating the uncoated portion of the sample surface with an agent to cause damage to the enamel of the uncoated sample surface;
• (d) covering a portion of the damaged sample surface with an impermeable removable coating (e.g., half of the damaged sample surface), e.g., as a positive control;
• (e) treating the remaining portion of uncoated, damaged sample surface with the test composition, e.g., as the test surface;
• (f) removing the impermeable, removable coatings;
• and
• (g) analyzing and comparing the differences between the three portions of the sample surface (the undamaged untreated negative control surface, the damaged untreated positive control surface, and the damaged treated test surface).
