Patterns of Enamel Protein Elements in the Mouse Incisor
Protein elements have been known to exist in enamal, but their structure and role in the final formation of enamel have not always been agreed upon."" 8.9. fl 23,4,a, le,17,1824,25,26 In 1933 a "ladder-like" process was described by Kitchen in relation to newly formed enamel in the mandibular incisor of the white rat.1' Previously, Bibby reported an increase in the organic elements of hypoplast...
متن کاملProtein content of molar-incisor hypomineralisation enamel.
OBJECTIVES The aim of the study was to compare the relative amounts and nature of the proteinous content of sound and molar-incisor hypomineralisation (MIH) enamel. METHODS TCA (20%) was used to dissolve the mineral phase and precipitate the proteins from enamel pieces sectioned from sound and MIH enamel. The protein content was estimated using a miniaturized version of the method of Lowry et...
متن کاملMapping residual organics and carbonate at grain boundaries and the amorphous interphase in mouse incisor enamel
Dental enamel has evolved to resist the most grueling conditions of mechanical stress, fatigue, and wear. Adding insult to injury, it is exposed to the frequently corrosive environment of the oral cavity. While its hierarchical structure is unrivaled in its mechanical resilience, heterogeneity in the distribution of magnesium ions and the presence of Mg-substituted amorphous calcium phosphate (...
متن کاملCritical role for αvβ6 integrin in enamel biomineralization.
Tooth enamel has the highest degree of biomineralization of all vertebrate hard tissues. During the secretory stage of enamel formation, ameloblasts deposit an extracellular matrix that is in direct contact with the ameloblast plasma membrane. Although it is known that integrins mediate cell-matrix adhesion and regulate cell signaling in most cell types, the receptors that regulate ameloblast a...
متن کاملTooth enamel biomineralization in extant horses: implications for isotopic microsampling
Isotopic analyses of tooth enamel from fossil equids are increasingly being used to reconstruct paleoclimatic and paleoenvironmental conditions. However, the accuracy of these reconstructions is currently limited, partly because the precise timing and spatial patterns of enamel mineralization in equids have not been documented. We used radiographic analyses of mandibles collected from modern ju...
