High magnification transmission electron microscopy (TEM) imaging, showing that the collagen fibrils structure in dentin specimens crosslinked with RFLi0.5%/0.5% remained intact and exhibited a consistent periodicity pattern even after 3 months of storage. (A-C) Control; (D-F) RFLi0.5%/0.25%; (G-I) RFLi 0.5%/0.5%. In a higher magnification of the TEM images, it can be seen even clearer where the crosslinking is being formed, shown by the red circles and yellow arrows.
