ANT415H5 Lecture Notes - Lecture 9: Canine Tooth, Deciduous Teeth, Permanent Teeth
Document Summary
Recall: the dental arcade the arrangement of teeth in jaws. 4 types of teeth incisors: canines, premolars, molars. Number of teeth change, the shape and sizes of teeth change considerable: can be used to narrow down genus/species. Mandibular tooth # = subscript e. g. m3=permanent third mandibular molar. Heterodont: any animal with heterodont dentition, having teeth of different sizes and shapes e. g. differentiated into incisors, canines, premolars, e. g. dogs, humans. Homodont: having teeth that are all of similar form or, having all the teeth similar in the front, e. g. porpoises, alligators, crocodile. 2 distinctive types of teeth that differences in patterns of growth and morphology. Brachydont (low crowned teeth: e. g. humans, carnivores (dogs, cats), pigs. Hypsodont (high crowned teeth: e. g. permanent teeth of horses, cheek teeth of ruminants (cattle, sheep, goats) Organizing the donts refer to the dentition page. Dogs: do have grinding surface on molars: 3142/3143. Will not have to remember formula on the test.
