dentine

dentine

The hard, calcified tissue that makes up the greater thickness of the tooth. It is denser and harder than bone, but softer than the outer enamel coating and contains tubules of cells which connect the inner pulp of the tooth to the surface.

dentine

the calcified tissue surrounding the pulp cavity of a tooth. Dentine is acellular, but like bone in structure. It is penetrated by cellular processes from the central cavity of the tooth which secrete the enamel.

dentine,

n See dentin.

dentine

one of the hard tissues of the teeth which constitutes most of its bulk. Lies between the pulp cavity and the enamel, and where it is not covered by enamel is covered by cementum, the third hard substance of the tooth.

sclerotic dentine
a dense clear dentine formed when the dentinal tubules are filled with mineralized material.
secondary dentine
dentine laid down in later development of a tooth, helping to avoid the exposure of the tooth pulp. It is often pigmented and is responsible for the appearance of the dental star.
tertiary dentine
produced in response to irritation of odontoblastic processes. Called also reparative dentine.
