From: Reactionary and reparative dentin formation after pulp capping: Hydrogel vs. Dycal
a After 4 weeks of Hydrogel capping, the figure shows the closure of the isthmus located between the pulp horns (arrows). The mesial pulp horn is unmineralized (white asterisk). b Reactionary dentin (rd) is massively formed 4 weeks after capping in the mesial part of the molar. c Reparative dentin (rep) fills partially the distal horn. Behind a calciotraumatic line (ctl), reactionary dentin (rd) is appended. d Large preparation (arrow) of the occlusal cavity cannot be repaired spontaneously. Reparative (rep) and reactionary (rd) dentins are formed in the mesial and distal parts of the pulp. Bars: 100 μm
