Induction of Reparative Dentin Formation on Exposed Dental Pulp by Dentin Phosphophoryn/Collagen Composite

Figure 1

Micrographs showing upper first molars 1(a), 2(b), and 3 weeks ((c) and (d)) after treatment with DPP-Col. The compact reparative dentin was formed adjacent to the primary dentin at 2 weeks (b). The exposed pulp tissue was covered completely with reparative dentin at 3 weeks (c). Reparative dentin has dentinal tubules (asterisk) and regular arrangement of odontoblasts at 3 weeks ((d) higher magnification of the highlighted region in (c)). D: dentin, P: pulp tissue, and R: reparative dentin. Scale bar ((a), (b), and (c)) = 500 μm. Scale bar (d) = 100 μm.
