Comparison of Methods for Evaluating Mineral Loss: Hardness versus Synchrotron Microcomputed Tomography
(Karger, 2009-01-01)
This study analyzed degrees of demineralization in bovine enamel using synchrotron microcomputed tomography (SMCT) and hardness measurements (Knoop hardness number, KHN). For 5 days, 40 bovine enamel blocks were individually ...
