Dental enamel

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 ...

Effect of divalent metal cations on hydroxyapatite dissolution kinetics relevant to dental caries and erosion. [PDF]

open access: yes, 2012
PhDIn recent years there has been an increasing awareness of the influence of various trace elements on reducing the progression of dental caries and of erosion. However, there are few clinical and even fewer in-vitro studies of the cariostatic effect of

Intraspecific variation in M1 enamel development in modern humans: implications for human evolution [PDF]

open access: yes, 2008
The timing and sequence of enamel development, as well as enamel thickness, was documented for individual cusps (protoconid, hypoconid,metaconid, entoconid) in 15 unworn permanent lower first molars (M1s) from a sample of modern human juveniles.

Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups

open access: yesJournal of Applied Oral Science, 2014
Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface.

An in vitro study of the wear mechanism of a leucite glass dental ceramic

open access: yesBiosurface and Biotribology, 2015
Ceramics and glass-ceramics are materials of choice for dental crowns due to their attractive hardness, biocompatibility, etc. However, a major problem with their usage is the observed high wear of either the opposing dental enamel or both the enamel and

Developmental and Post-Eruptive Defects in Molar Enamel of Free-Ranging Eastern Grey Kangaroos (Macropus giganteus) Exposed to High Environmental Levels of Fluoride. [PDF]

open access: yesPLoS ONE, 2016
Dental fluorosis has recently been diagnosed in wild marsupials inhabiting a high-fluoride area in Victoria, Australia. Information on the histopathology of fluorotic marsupial enamel has thus far not been available. This study analyzed the developmental
