Figure 3

Micrographs showing upper first molars 1(a), 2(b), and 3 weeks (c) after treatment with Ca. Reparative dentin having gaps and tunnel defects was observed at 2 weeks (arrow). This dentin still contained gaps and tunnel defects at 3 weeks. A necrotic superficial layer (N) formed beneath the material. D: dentin, P: pulp tissue, and R: reparative dentin. Scale bar = 500 μm.
