In animal tooth development, dentinogenesis is the formation of dentin, a substance that forms the majority of teeth.Dentinogenesis is performed by odontoblasts, which are a special type of biological cell on the outer wall of dental pulps, and it begins at the late bell stage of a tooth development.
A veterinary physician performing dental work on a grey mare. Equine dentistry is the practice of dentistry in horses, involving the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, maxillofacial area and the adjacent and associated structures.
Hertwig epithelial root sheath initiates the formation of dentin in the root of a tooth by causing the differentiation of odontoblasts from the dental papilla. The root sheath eventually disintegrates with the periodontal ligament, but residual pieces that do not completely disappear are seen as epithelial cell rests of Malassez (ERM). [1]
In horses and most equines the cross section of the tooth at the grinding (occlusal) surface shows the roughly circular or ovoid infundibulum as the incisor begins to wear. [4] When the horse's incisor has grown in enough to connect with the incisor in the other jaw (lower jaw with upper), then wear begins as the horse grinds its teeth back and ...
Horse teeth refers to the dentition of equine species, including horses and donkeys. Equines are both heterodontous and diphyodontous , which means that they have teeth in more than one shape (there are up to five shapes of tooth in a horse's mouth), and have two successive sets of teeth, the deciduous ("baby teeth") and permanent sets.
Veterinary dentistry involves the application of dental care to animals, encompassing not only the prevention of diseases and maladies of the mouth, but also considers treatment. In the United States , veterinary dentistry is one of 20 veterinary specialties recognized by the American Veterinary Medical Association .
Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
These materials protect the pulp from noxious agents (heat, cold, bacteria) and stimulate the cell-rich zone of the pulp to lay down a bridge of reparative dentin. Dentin formation usually starts within 30 days of the pulp capping (there can be a delay in onset of dentin formation if the odontoblasts of the pulp are injured during cavity ...
