A calciotraumatic line (CTL) separates the tubular secondary dentin (D) from the reactionary dentin (RD) formed in response to the treatment of carious lesion of human premolar (young adult). Odontoblasts (O) located in the outer layer of the pulp (P) synthetize and secrete the components of predentin (PD). Hematoxylin-eosin staining. P: pulp.
