Sagittal sections of maxillary (A, B, C) and mandibular (D, E, F) teeth in alveolar bone at the incisal (C, F), premolar (B, E), and molar (A, D) levels. Labial or buccal surface is to the right (×2.2).
Sagittal section of a maxillary molar in situ. The cortical bone (CAB), alveolar bone proper (ABP), and trabecular alveolar bone (TAB) form the alveolar process, which ends at the margin of the alveolus as the alveolar crest (ACB). The alveolar process is continuous with the basilar bone (BB) of the maxilla. A small part of the maxillary sinus (MXS) is also visible (H and E stain; ×16).
Transverse section of the root of an incisor with surrounding alveolar bone (B) (H and E stain; ×16).
