From: Reactionary and reparative dentin formation after pulp capping: Hydrogel vs. Dycal
Hydrogel capping after 1 week (a, b). Slight inflammation is seen near the capping material. c Two weeks after capping with Dycal, reparative dentin bridge (rep) is seen in the right part of the figure. Necrotic pulp (np) and vital pulp (vp) form a layer beneath the dentinal bridge, followed by vital pulp. A calciotraumatic line (ctl) separate the dentin formed prior to the cavity preparation from reactionary dentin (rd) formed after capping. d After Hydrogel capping for 2 weeks, calcospherites (spheroid formation) (asterisks) constitute the loci of initial mineralization.
