From: Reparative dentin formation as a possible factor influencing the penetrability of dentin in human teeth with apical periodontitis: an ex vivo study

Fig. 1

Representative images of dye penetration and hematoxylin–eosin (HE) staining, revealing that the dye penetration is more superficial in (A) the infected root canals than (B) root canals with normal healthy pulp. (A2) The reparative dentine, influences the penetrability of root dentine. (A) Left mandibular first molar of a 19-year-old woman with a destroyed crown and periapical lesions. (A1-1/2/3) Results of methylene blue staining in the distal root canal (black arrow in A). (A2-1/2/3) Results of HE staining of the same section. Yellow arrow indicates reparative dentine, formation in the apical section. (B) Healthy tooth 38 (left mandibular third molar) of a 24-year-old woman. (B1-1/2/3) Images of methylene blue staining of the distal root canal (black arrow in B). The dye is spreading evenly through the dentin tubules. (B2-1/2/3) HE staining of the same section, absent of reparative dentin
