Role of attrition and occlusal contact in the physiology of the rat incisor: IX. Impeded and unimpeded eruption in lathyritic rats. 1975

Y Michaeli, and S Pitaru, and G Zajicek, and M M Weinreb

In the rat, the administration of a lathyrogenic agent reduced both impeded and unimpeded eruption rates of incisors. Unimpeded eruption rates were greater than impeded eruption rates. The general eruption pattern in the experimental rats was, however, similar to that in the control rats. Thus, eruption was possible even in rats with a lathyrogenically impaired periodontal ligament.

UI	MeSH Term	Description	Entries
D007180	Incisor	Any of the eight frontal teeth (four maxillary and four mandibular) having a sharp incisal edge for cutting food and a single root, which occurs in man both as a deciduous and a permanent tooth. (Jablonski, Dictionary of Dentistry, 1992, p820)	Incisors
D007842	Lathyrism	A paralytic condition of the legs caused by ingestion of lathyrogens, especially BETA-AMINOPROPIONITRILE or beta-N-oxalyl amino-L-alanine, which are found in the seeds of plants of the genus LATHYRUS.	Neurolathyrism
D008297	Male		Males
D008310	Malocclusion	Such malposition and contact of the maxillary and mandibular teeth as to interfere with the highest efficiency during the excursive movements of the jaw that are essential for mastication.

D003766	Dental Occlusion	The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication.

D000629	Aminopropionitrile	Reagent used as an intermediate in the manufacture of beta-alanine and pantothenic acid.	beta-Aminopropionitrile,BAPN,beta Aminopropionitrile
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014072	Tooth Abrasion	The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action.
