| Outline of Final Research Achievements |
Glycation, namely the Maillard reaction, is a non-enzymatic reaction between protein or lipid and reducing sugar, resulting in formation of advanced glycation end-products (AGEs). Because glycation of collagen progresses under physiological conditions in living organisms, glycation is one of the most important processes in human aging. Several AGEs bind collagen and act as cross-links between collagen fibrils, thereby changing the fluorescent lifetime of collagen-rich tissues. The purpose of this study is to identify AGEs in human dentin using electron microscopy, time-resolved fluorescence microscopy, mechanical testing and chemical analyses. Our findings suggest the potential influence of cross-linking on diabetic and aging tissue.
