41Ca in tooth enamel. part I: A biological signature of neutron exposure in atomic bomb survivors [PDF]

, 2010
The detection of 41Ca atoms in tooth enamel using accelerator mass spectrometry is suggested as a method capable of reconstructing thermal neutron exposures from atomic bomb survivors in Hiroshima and Nagasaki.

Using microstructures and composition to decipher the alterations of rodent teeth in modern regurgitation pellets—a good news-bad news story

, 2020
Rodent accumulations are widely used for palaeoenvironmental reconstructions. But these accumulations are created through the activity of predators (carnivorous mammals, birds of prey), the predation and digestion of which modify the preservation of ...

Advances in biomimetic mineralization of tooth enamel based on cell-free strategies [PDF]

MATEC Web of Conferences, 2022
Tooth enamel is a highly-mineralized hard tissue covering the outermost layer of the dental crown, and amelogenesis is inseparable from the participation of necessary components such as ameloblasts, organic matrix proteins, and mineral ions, such as Ca2+

Remineralization strategies in oral hygiene: a position paper of Italian Society of Oral Hygiene Sciences-S.I.S.I.O. working group [PDF]

, 2017
Background/Objective: The clinical conditions that lead to an alteration of the enamel structure are numerous. The diet high in sugars and acidifying substances, psychological stress that triggers parafunctional behaviors, the reduced intake of fiber ...

Aluminablasting of human tooth enamel

Journal of Materials Science: Materials in Medicine, 1997
As part of a programme aimed at enhancing the degree of bonding that can be developed between dental polymer and human tooth enamel, the enamel has been subjected to two types of pretreatment, namely, aluminablasting (a mechanical etching) and aluminablasting followed by surface etching with orthophosphoric acid. Analysis of the surfaces so prepared by

Evaluation of calcium and magnesium contents in tooth enamel without any pathological changes: in vitro preliminary study

Odontology : official journal of The Society of the Nippon Dental University, 2018
Enamel is the structure that covers the entire clinical crown of a tooth. It enables to chew and crush food, and gives a final shape to the crowns of teeth.

The better to eat you with: morphological disparity and enamel ultrastructure in odontocetes

Scientific Reports, 2023
Variations in the shape and size of teeth have been associated with changes in enamel ultrastructure across odontocetes. Characterizing these features in extinct taxa can elucidate their functional morphology and feeding strategy, while also shedding ...
