Histological details of the transverse sections on slides 2, 3, 5, 7 (BSPG AS XIX 504b, c, e, g). a, c, f and g seen in normal transmitted light, d, in polarised light and b, e and h in polarized light with lambda compensator. a, b Close-up of striated enamel and orthodentine (slide 2). Note interglobular zone of dentine at enamel–dentine junction. c, d Central pulpal area of tooth showing vascular canals in the orthodentine (slide 5). e Central area of tooth with vascular canals surrounded by orthodentine (slide 3). f Close-up of vascular canal seen in c (slide 5). Note how dentine tubules deviate around the canal. g, h Close-up of the cementum–dentine junction at the level of the neck of the tooth (slide 7). Note zones of acellular cementum and the granular layer of Tomes. AC acellular cementum, CC cellular cementum, DT dentine tubules, E enamel, GT granular layer of Tomes, IGZ interglobular zone of orthodentine, OD orthodentine, VC vascular canals
