Biological Clocks and the Formation of Human Tooth Enamel
Tooth enamel contains relics of its formation process, in the form of microstructures, which indicate the incremental way in which it forms during enamel formation on teeth (). These microstructures, called cross-striations and striae of Retzius, develop as enamel-forming cells called ameloblasts, which cyclically deposit enamel on developing teeth in accordance with two different biological cl...
متن کاملBiosynthesis and characterization of rabbit tooth enamel extracellular-matrix proteins.
Tooth enamel biomineralization is mediated by enamel proteins synthesized by ameloblast cells. Two classes of proteins have been described: enamelins and amelogenins. In lower vertebrates the absence of amelogenins is believed to give rise to aprismatic enamel; however, rabbit teeth, which apparently do not synthesize amelogenins, form prismatic enamel. The present study was designed to charact...
متن کاملHelium ion microscopy of enamel crystallites and extracellular tooth enamel matrix
An unresolved problem in tooth enamel studies has been to analyze simultaneously and with sufficient spatial resolution both mineral and organic phases in their three dimensional (3D) organization in a given specimen. This study aims to address this need using high-resolution imaging to analyze the 3D structural organization of the enamel matrix, especially amelogenin, in relation to forming en...
متن کاملRemineralization of artificial enamel lesions by theobromine.
OBJECTIVE This study investigated the remineralization potential of theobromine in comparison to a standard NaF dentifrice. METHODS Three tooth blocks were produced from each of 30 teeth. Caries-like lesion was created on each block using acidified gel. A smaller block was cut from each block for baseline scanning electron microscopy imaging and electron-dispersive spectroscopy (EDS) analysis...
متن کاملNovel biological activity of ameloblastin in enamel matrix derivative
OBJECTIVE Enamel matrix derivative (EMD) is used clinically to promote periodontal tissue regeneration. However, the effects of EMD on gingival epithelial cells during regeneration of periodontal tissues are unclear. In this in vitro study, we purified ameloblastin from EMD and investigated its biological effects on epithelial cells. MATERIAL AND METHODS Bioactive fractions were purified from...
