Prof. Dr. Buchalla

In Fluorescence Aided Caries Excavation (FACE) the disparity of the reflecting nature of carious and healthy tooth substance is used to visualize the edge between them and to enable a better excavation. In the second part of the lecture Professor Dr. Wolfgang Buchalla, University of Regensburg/Germany, introduces the method and the clinical results.

Prof. Buchalla compare this method for caries excavation with other known techniques regarding the length of time needed, the effectiveness and the efficiency. With a sample of 40 molars with carious lesions he was able to proof that infected dentin usually show a read fluorescence (sensivitity: 94%). If there is no red fluorescence the dentin is normally free of bacteria (specifity: 95%). The tactile methods like probing the dentin surface or the dyeing with caries detectors show a sensitivity of 76% resp. 65%. 

Another study, using 60 extracted molars, showed that with FACE the smallest amount of infected dentin was left behind. So the edge between carious and healthy tooth substance is identified best with FACE.
