The resistant dentine shell of teeth suffering from idiopathic external resorption. 1980

H B Yaacob

Histological examination of 18 erupted and eight unerupted teeth with idiopathic external resorption demonstrated that the pulp remained protected by a thin layer of dentine approximately 23--308 micrometers wide. There was no significant difference between erupted and unerupted teeth.

D003786	Dental Pulp Cavity	The space in a tooth bounded by the dentin and containing the dental pulp. The portion of the cavity within the crown of the tooth is the pulp chamber; the portion within the root is the pulp canal or root canal.

D003804	Dentin	The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected.

D014078	Tooth Eruption	The emergence of a tooth from within its follicle in the ALVEOLAR PROCESS of the MAXILLA or MANDIBLE into the ORAL CAVITY. (Boucher's Clinical Dental Terminology, 4th ed)	Teething,Eruption, Tooth,Eruptions, Tooth,Tooth Eruptions
D014091	Tooth Resorption	Resorption of calcified dental tissue, involving demineralization due to reversal of the cation exchange and lacunar resorption by osteoclasts. There are two types: external (as a result of tooth pathology) and internal (apparently initiated by a peculiar inflammatory hyperplasia of the pulp).

D014097	Tooth, Unerupted	A normal developing tooth which has not yet perforated the oral mucosa or one that fails to erupt in the normal sequence or time interval expected for the type of tooth in a given gender, age, or population group.	Teeth, Unerupted,Unerupted Teeth,Unerupted Tooth
