Tooth-like structures were generated in which the epithelial cells differentiated into enamel-secreting ameloblasts. The formation of enamel, the hardest tissue of the body (see Section 2.2.1), is an important step in generating whole teeth, but also would be of importance for repair or ...
These structures can also be considered as multifunctional (multipurpose) materials if we take into account the fact that their inner design is aimed at achieving mechanical anisotropy (Weiner et al., 2000). A multipurpose function of tooth enamel is realized as a response of the material to ...
one of the small bonelike structures of the jaws for biting and mastication of food; they also help in the shaping of sounds and forming of words in speech. Structure. The portion of a tooth that rises above the gum is the crown; the portion below is the root. The crown is covered ...
One of the structures found in the mouth of most vertebrates which, in their most primitive form, were conical and were usually used for seizing, cutting up, or chewing food, or for all three of these purposes. The basic tissues that make up the vertebrate tooth are enamel, dentin, cement...
Understanding the relations between the mechanical responses of whole entities, their materials properties and their structures, is a challenge. This challenge is greatly enhanced when the material itself is complex, and when the entity it forms has a convoluted shape. It is for these reasons that...
with different structures11. In addition, in these structures, dentin tubules are less frequent, and its primary goal is to protect the pulpal tissue from irritants12. The odontoblasts and surrounding dentin layer are often jointly referred to as the dentin complex, as their function is highly...
with varying patterns of localisation and expression compared to mammals, and structures at least partially homologous to mammalian enamel knots (non-proliferative signalling centres of ectodermal cells) determine tooth shape in some squamate clades16,18,19. In mammals—the most commonly studied dental ...
permanent tooth- any of the 32 teeth that replace the deciduous teeth of early childhood and (with luck) can last until old age adult tooth tooth- hard bonelike structures in the jaws of vertebrates; used for biting and chewing or for attack and defense ...

Dental pulp is a loose, highly specialized connective tissue surrounded by the rigid structures of the tooth, namely, enamel (the outermost layer and the most rigid substrate of the human body) and dentin (the layer positioned underneath enamel and right on top of pulp), forming a hierarchicall...
