Teeth are hard, calcified structures found in the human mouth. They are used primarily for chewing food, but also play an important role in speech and maintaining the structure of the face. Teeth are composed of different tissues, including enamel, dentin, pulp, and cementum. Enamel is the ...
Teeth are composed of multiple tissues of varying density and hardness, including enamel, the hardest substance in the human body, which covers the outer layer of each tooth. Proper dental care, including regular brushing, flossing, and dental check-ups, is vital for maintaining tooth health and...
Teeth are not considered bones because they have distinct structural and compositional differences. Teeth are made up of enamel, dentin, pulp, and cementum, while bones consist of compact bone, spongy bone, and bone marrow. Teeth primarily serve the purpose of chewing and breaking down food, wh...
The simplest teeth are composed of stacked rod-like elements with solid calcite tips. More advanced teeth underwent continuous replacement of tooth elements, as a simple self-sharpening mechanism. Within echinoids tooth design was refined by evolving thinner, flatter primary plates with buttressing, ...
The teeth are multifunctional appendages that essential in basic human functions, like eating and speech. Teeth are composed of multiple unique tissues with varying density and hardness that allows them to tolerate the significant forces and wear of mastication. They are attached to the maxilla (uppe...
What a goose does have instead of true goose teeth are sharp serrated edges called tomia. These differ from true teeth in a few important respects. First, tomia is composed of cartilage rather than enamel; this is essentially the same substance found in joints, ears, noses, and vertebral dis...
There’s no shortage of fossil archosaurs now named solely from teeth, or partial jaw bones but diagnosed or described primarily on teeth. Last I checked, this number was well over 150. Most recently, some of these used to be dinosaurs, but have subsequently been removed due tot he finding...
A hamartoma is a benign growth that resembles a neoplasm in the tissue of its origin. It is composed of tissue elements normally found at that site, but that are growing in a disorganized mass. ○ Elodontomas of the maxillary incisors appear to be common in captive degus. ○ The underlyin...
Gene expression during stages of tooth development in the shark highlights the highly conserved genetic mechanism that forms the basis to the core ‘odontode’ unit: tooth-like structures including teeth, skin denticles and other skin ornaments composed of dentine and enamel-like tissues (Debiais-...
fix small gaps in the teeth. They are utilized for children as effectively as adults.Brackets are composed of two main elements. One part is the headband that will fits over typically the head and will be pulled back at certain points simply by means of little bands. These rings exert a ...
