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.

The objectives were to evaluate the surface morphology of the remaining dentine after caries removal with the conventional method of using drills and a chemo-mechanical method using Papacarie[R] and CH and further comparing the resin tags formed at the resin-dentine interface.
The similarity between the different dentine layers suggests the isotopic signature of Paramylodon is unaltered at this locality; diagenesis would likely have impacted the inner and outer layers differently.
This clearly differs from the spine primordium where the mesenchyme cells adjacent to the enamel organ had taken the form of what appeared to be a well defined dentine organ prior to any matrix deposition.
The capacity of actinomycetes to colonize mucosal surfaces and dentine appears to depend on two distinct fimbriae, type 1 and type 2, that bind preferentially to salivary acidic proline-rich proteins and to statherin, or to [beta]-linked galactose or galactosamine structures on epithelial or bacterial surfaces, respectively (28).
The dorsal spines occur just in front of the two dorsal fins and are made of dentine surrounded by a thin coat of enamel.
In a first full volume on dental erosion, restorative dentists from Europe and the US consider such aspects as defining erosion and its links to tooth wear, diagnosis, the chemistry, extrinsic and intrinsic causes, children, dentine hypersensitivity, and restorative therapy.
