Dental enamel [PDF]

open access: yesSouth African Dental Journal, 2020
Dental enamel is the sparsest but most enduring component of all the tissues in the human body, yet contrarily contains the most detailed historiography of its development. Accordingly, analysis of enamels' chemistry, histology and pathology can reveal detailed ambient information of both fossilized, long-deceased and its contemporary milieu occurring ...

Weaker dental enamel explains dental decay. [PDF]

open access: yesPLoS ONE, 2015
Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free ...

Translucency of Human Dental Enamel [PDF]

open access: yesJournal of Dental Research, 1981
Translucency of human dental enamel was determined by total transmittance of wavelengths from 400 to 700 nm. The transmission coefficient at 525 nm was 0.481 mm -1 . Total transmission of light through human dental enamel increased with increasing wavelength.

The crystallographic structure of dental enamel and related apatites [PDF]

open access: yes, 1964
PhDSynthetic, biological and mineralogical carbonate-containing apatites have been studied, principally by infra-red absorption spectroscopy (using polarised or unpolarised radiation), The substitution of a carbonate ion for two hydroxyl ions in the ...

The Complexity of Dental Enamel [PDF]

open access: yes, 2022
Dental enamel constitutes the least quantitative and rarest component of all tissues in the human body but is the most enduring and hardest constituent of ecto dermal cellular development.

The effects of smoothies on enamel erosion: an in situ study [PDF]

open access: yes, 2012
Aims: To measure, in vitro, the pH and titratable acidity (TA) of various soft drinks and to assess the effect of smoothies on erosive tooth surface loss of enamel following a 21-day pH cycling protocol using an in situ model. Methods: The inherent pH of

The Epidemiology, Aetiology, and Histopathology of Developmental Enamel Defects in Human Teeth [PDF]

open access: yes, 1983
PhDThe prevalence of developmental enamel defects in t11 permanent dentition was investigated in a sample of 2923 East London schoolchildren aged 5 to 15 years. Enamel discolourations and hypoplasias were identified using well defined criteria.

The fracture behaviour of dental enamel [PDF]

open access: yesBiomaterials, 2010
Enamel is the hardest tissue in the human body covering the crowns of teeth. Whereas the underlying dental material dentin is very well characterized in terms of mechanical and fracture properties, available data for enamel are quite limited and are apart from the most recent investigation mainly based on indentation studies.

Sintering of Dental Porcelain Enamels [PDF]

open access: yesJournal of Dental Research, 1976
This study showed the effects of sintering temperature and atmospheric pressure on the density, tensile strength, and microstructure of porcelain enamels. Although the densities of the opaque porcelains were higher, they were weaker than the gingival porcelains.
