A mathematical model for the progression of dental caries [PDF]

open access: yesMathematical Medicine and Biology, 2013
A model for the progression of dental caries is derived. The analysis starts at the microscopic reaction and diffusion process. The local equations are averaged to derive a set of macroscopic equations. The global system includes features such as anisotropic diffusion and local changes in the geometry due to the enamel melting.
