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.

Several studies have shown that a significant number of parents whose children have baby bottle tooth decay (BBTD) admit prior knowledge regarding the harmful effects of putting their children to bed with a bottle. The Elaboration Likelihood Model of Persuasion (ELM) offers a theoretical framework for better understanding why knowledge and attitude are often not predictive of behavior. The goal...
