Mathematics of Tooth Decay

Molecular Tooth Decay

Charles Darwin was intrigued with vestigial organs and, in fact, made them a part of his ‘‘long argument’’ for the existence of evolution in the natural world in Chapter 13 of On the Origin of Species. Now on the 150 anniversary of the publication of that seminal work, a study linking vestigial organs with molecular biology with paleontology has shown even more clearly how vestigial organs are ...

Factors Associated with Specific Patterns of Tooth Decay 33

Dental caries affects most adults worldwide; however, the risk factors for dental caries do not necessarily exert their effects uniformly across all tooth surfaces. Instead, the actions of some risk factors may be limited to a subset of teeth/surfaces. Therefore, we used hierarchical clustering on tooth surface-level caries data for 1,068 Appalachian adults (ages 18-75 yrs) to group surfaces ba...

Diagnosis of Tooth Decay Using Polarized Micro-raman Confocal Spectroscopy

The tooth enamel presents a Raman spectrum with strong polarization anisotropy. Carious lesions of the enamel will produce an alteration of local symmetry. This will reduce the anisotropy of the Raman spectra. Thus micro-Raman polarized spectroscopy could be a used in early detection of teeth caries.
