Cementum forming on a developing root. Cementoblasts (CB) have deposited a layer of cementoid (CD) on the surface of root dentin (D) at the dentinocemental junction (DCJ). Hertwig’s root sheath (HRS) has induced more odontoblasts (OD) from the pulp (H and E stain; ×400).
Transverse section of a tooth in situ. Acellular cementum (AC) has been deposited on the dentin (D). The dentinocemental junction (DCJ) is prominent. Periodontal ligament (PDL) extends from the cementum to the alveolar bone (B) (H and E stain; ×160).
Higher magnification of the dentinocemental junction (DCJ), acellular cementum (AC), and periodontal ligament (PDL) shown in Fig 5-2 (×400).
Cementoblasts (CB) and cementoid (CD) on the surface of acellular cementum (AC) (H and E stain; ×640).
Sharpey’s fibers (SF) in acellular cementum (H and E stain; ×400).
