Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

We report on the use of a blue laser diode to excite natural fluorescence from a range of dentalsamples. Sixty teeth with naturally occurring lesions were examined. The lesions were classified onvisual inspection as falling into three classes as shiny lesions, dull lesions and brown lesions. Theresulting fluorescence was then examined using a fibre optically coupled spectrometer in a series ofwavelength bands. By examining the intensity ratios in the two wavelength bands 480-500nm and620 to 640nm we were able to classify the lesion types and thus provide a quantifiable measurementof lesion types. This method has application for detection of dental caries as well as demonstratingpotential application to evaluate lesions which may represent different degrees of caries activity.
