TF group, control side: a overview of the histopathologic preparation of healthy bone stock; Giemsa-Eosin-stained section. bf Corresponding sections in detail; native and fluorescence. e–g Note that the viable bone is again marked by ordered collagen bands and bone cells (corresponding to the microscopic view of the auto-fluorescence group). Arrow: fluorescence is mainly caused by ordered collagen-bands. (*) Tetracycline fluorescence bands at the edge areas with new bone formations. Overall, no histologic difference can be seen between those two techniques
