A method is provided for scanning the surface of an object in which moisture such as saliva or water is present on the surface. The method includes the step of applying a saliva and water-resistant composition to the surface, wherein the composition is characterized in that it does not readily wash off the surface after application of the composition to the surface in the presence of saliva or water. The composition forms an opaque film on the surface. The method further includes the step of scanning the surface having the film with a scanner. Several formulations for the composition are disclosed. One includes a liquid alcohol base, such as dehydrated ethyl alcohol, a reflective pigment, and a binder for promoting good adhesion of the formulation to the surface of the object being scanned.
