Biomimetic Remineralization of Demineralized Dentine Using Scaffold of CMC/ACP Nanocomplexes in an In Vitro Tooth Model of Deep Caries
Figure 11
Representative TEM images of unstained samples of completely demineralized dentine in the tooth model and corresponding SAED patterns (inserts).
(a) the control sample, showing faint banding characteristics (between open arrows) (b) the sample treated with CMC/ACP, showing characteristic type-I collagen D-bands (between open arrows), indicating intrafibrillar minerals within collagen fibrils after remineralization. (c) the sample treated with Ca(OH)2, showing faint banding characteristics (between open arrows) and needle-like crystals as extrafibrillar minerals.
