Structural Morphology of Molars in Large Mammalian Herbivores: Enamel Content Varies between Tooth Positions. [PDF]

open access: yesPLoS ONE, 2015
The distribution of dental tissues in mammalian herbivores can be very different from taxon to taxon. While grazers tend to have more elaborated and complexly folded enamel ridges, browsers have less complex enamel ridges which can even be so far reduced

Tooth Enamel and Its Dynamic Protein Matrix

open access: yesInternational Journal of Molecular Sciences, 2020
Tooth enamel is the outer covering of tooth crowns, the hardest material in the mammalian body, yet fracture resistant. The extremely high content of 95 wt% calcium phosphate in healthy adult teeth is achieved through mineralization of a proteinaceous ...

Uneven distribution of enamel in the tooth crown of a Plains Zebra (Equus quagga) [PDF]

open access: yesPeerJ, 2015
Unworn teeth of herbivorous mammals are not immediately functional. They have to be partially worn to expose enamel ridges which can then act as shear-cutting blades to break the food down.

Wear of human teeth: a tribological perspective [PDF]

open access: yes, 2005
The four main types of wear in teeth are attrition (enamel-on-enamel contact), abrasion (wear due to abrasive particles in food or toothpaste), abfraction (cracking in enamel and subsequent material loss), and erosion (chemical decomposition of the tooth)

Immediate performance of self-etching versus system adhesives with multiple light-activated restoratives [PDF]

open access: yes, 2004
Objectives: The purpose of this study was to evaluate the performance of both single and double applications of (Adper Prompt L-Pop) self-etching dental adhesive, when used with three classes of light-activated restorative materials, in comparison to the

Evaluation of the esthetic properties of developmental defects of enamel: a spectrophotometric clinical study [PDF]

open access: yes, 2015
Objectives. Detailed clinical quantification of optical properties of developmental defect of enamel is possible with spectropho- tometric evaluation. Developmental defects of enamel (DDE) are daily encountered in clinical practice. DDE are an alteration

Downregulation of FGF Signaling by Spry4 Overexpression Leads to Shape Impairment, Enamel Irregularities, and Delayed Signaling Center Formation in the Mouse Molar. [PDF]

open access: yes, 2019
FGF signaling plays a critical role in tooth development, and mutations in modulators of this pathway produce a number of striking phenotypes. However, many aspects of the role of the FGF pathway in regulating the morphological features and the mineral ...

Biochemical Composition of the Teeth and the Effect of the Various Chemical Elements on their Structure

open access: yesČeská Stomatologie a Praktické Zubní Lékařství, 2017
Introduction and objectives: The main objective of this review article is a detailed description of the tooth structure, bioorganic and bioinorganic composition of the tooth components, the protective biochemical process of tooth which can protect ...
