Teeth are of major importance for most vertebrates, and we will make a close study of the teeth of heterodont mammals. The four major tooth types— incisor,门齿 canine犬齿, premolar前臼齿, molar臼齿—are abbreviated by the first letter, with an uppercase letter for the maxillary teeth (I, ...
Some ammonoids have been found with structures still in the living chamber that are now recognized as jaws (beaks or mandibles) because small teeth, characteristic of those of the radula of extant Cephalopoda, lie between upper and lower jaws. The radulae so far found in ammonoids have the...
The teeth of sea-urchins are not to be compared with the other skeletal-structures of echinoderms. The tooth is constructed of two rows of calcitelements, which are connected by secondary calcareous deposits forming the functional tooth. The surface of the tooth is covered by a crust of calc...
Knowledge of the gross anatomy and occlusion pattern of molar teeth in rats is necessary to relate experiments on dental caries in rats to research on causes of caries in man. The gross anatomy of the crowns in rat molars is described, and a hypothetical account of occlusion is advanced.Cite...
