In occlusal view (2.1, 2.3, 2.5, and 2.7), white areas indicate enamel and black shaded areas indicate dentine; in both occlusal and side views stippled areas indicate cement. Anatomical terms in black text. Major features in all capital text, minor features in lowercase text. Measured dimensions in gray text and indicated by gray bars. 2.1, occlusal view of P3. 2.2, anterior view of P3. 2.3, occlusal view of upper molariform tooth (generalized P4-M2). 2.4, anterior view of upper molariform tooth. 2.5, occlusal view of p3. 2.6, buccal view of p3. 2.7, occlusal view of lower molariform tooth (generalized p4-m2). 2.8, posterior view of lower molariform tooth.
