Fluorescence-aided caries excavation

Dental caries is a bacteria-infected disease. After being
illuminated by an excitation light, the by-products of oral
bacteria, mainly porphyrins, can emit visible auto-fluorescence,
which can be used as a marker for bacteria-infected dentin. Thus
the auto-fluorescence signals have been employed as an aid for the
differentiation between infected and affected dentin and monitoring
caries excavation. In 2002 fluorescence-aided caries excavation
(FACE) was invented as an excavation device to improve the
efficiency and accuracy of caries removal.This study has
investigated a recent version of FACE.
