Clinical and Histological Evaluation of Direct Pulp Capping on Human Pulp Tissue Using a Dentin Adhesive System

Figure 1

Morphology of the pulp-dentin complex in control groups. (a) Control intact group. Normal pulp tissue with visible odontoblast cell layer (hematoxylin and eosin [H&E]). Scale bar = 50 μm. (b) View of the pulp-dentin complex after application of calcium hydroxide onto the exposed pulp. Complete dentin bridge and no inflammatory process in the remaining pulp (H&E). Scale bar = 1 mm. (b1) Fragment of the view seen in panel (b). Dentin bridge with tunnel defect (arrowhead) and particles of calcium hydroxide in the pulp and bridge (H&E). Scale bar = 200 μm. (b2) Fragment of the view seen in panel (b1). Dentin bridge with dentinal tubules (arrow) and new odontoblast cell layer (star) (H&E). Scale bar = 100 μm. D: dentin; DB: dentin bridge; OL: odontoblast layer; P: pulp; V: blood vessels. Arrow: dentinal tubules; arrowhead: tunnel defect; star: new odontoblast cell layer.
