The thickness was not evaluated in sites where the bridge was absent. Fig. 1 Photomicrograph of Site A. Buccolingual section. The drill-created cavity (C) containing much debris is separated from the pulp (P) by a thick and incomplete dentin bridge (DB). The newly formed hard tissue starting from the original dentin tissue covers only half of the exposed pulp. H&E staining (at original 20× magnification). Fig. 2 Detail of Figure 1. The dentin bridge (DB) is formed by tubular and well-oriented reparative dentin. The pulp (P) appears slightly disorganized with few scattered inflammatory cells. C = cavity. H&E staining (at original 100× magnification). Fig. 3 Detail of Figure 1. The pulp tissue (P) close to the newly formed dentin (DB) and surrounding the remaining defect appears disorga- nized, with many fibroblasts and few scattered inflam- matory cells.
