Tooth development involves complex interactions between epithelial and mesenchymal tissues. There are three overlapping phases: initiation, morphogenesis, histogenesis. During initiation, tooth germs appear along an invagination of the oral epithelium called the dental lamina. During morphogenesis, the shape of the tooth is determined.

Epithelial histogenesis during tooth development
Archives of Oral Biology, 2009This paper reviews the current understanding of the progressive changes mediating dental epithelial histogenesis as a basis for future collaborative studies. Tooth development involves morphogenesis, epithelial histogenesis and cell differentiation. The consecutive morphological stages of lamina, bud, cap and bell are also characterized by changes in ...

TNF signalling in tooth development
Current Opinion in Genetics & Development, 2004Mammalian tooth development has served as an excellent model system to investigate the intricate, interactive mechanisms of patterning, morphogenesis and cytodifferentiation during organogenesis. Teeth develop from interactions between epithelium and neural crest-derived (ecto)mesenchyme that are largely mediated by ligand-receptor signalling.

Developing a Tooth Restorability Index
Dental Update, 2005It is generally agreed that the inherent strength of a tooth is dependent on the remaining dentine. It therefore seems logical that preservation of coronal dentine is important to the survival of intra- and extra-coronal restorations. The clinical assessment of the amount of dentine needed for functional requirements and the strategic value of ...

Abstract The histogenesis of tooth development in five species of sharks was investigated by the use of light microscopy, microradiography and electron microscopy. The highly mineralized outer cap of tissue on shark teeth is not enamel but a form of modified dentine.

MicroRNAs: Modulators of Tooth Development
MicroRNA, 2016MicroRNAs (miRNAs) are non-coding RNAs that are involved in various biological pathways by regulating gene expression. Teeth develop via reciprocal and sequential interactions between the epithelium and the ectomesenchyme. The speci.c functions of several genes during tooth development are known, and the involvement of their mutations in the ...

Molecular regulation of tooth development
Bone, 1999Teeth are organs that are only found in the oral cavity of vertebrates. Although they are composed of mineralized tissues and they are attached to bone, they do not form as outgrowths of bone. In fact, tooth development starts in the embryonic oral epithelium well before bone formation, and osteogenesis of the alveolar bone is later regulated by the ...

ALK5 is essential for tooth germ differentiation during tooth development
Biotechnic & Histochemistry, 2019The TGFβ superfamily of proteins participates in tooth development. TGFβ1 and TGFβ3 regulate odontoblast differentiation and dentin extracellular matrix synthesis. Although the expression of TGFβ family member ligands is well-characterized during mammalian tooth development, less is known about the TGFβ receptor, which is a heteromeric complex ...

Microscopic examination of ground and decalcified sections of enamel and dentin shows an incremental stratification of pairs of alternating light and dark layers. These layers follow a concentric pattern in transverse sections and resemble the annual rings in trees. The incremental stratifications have been more generally known as the striae of Retzius

Tooth Development in Protemnodon eugenii
Journal of Dental Research, 1972Tooth development was studied in a series of pouch-young specimens of Protemnodon eugenii. The single replacing premolar originated from the dental lamina that is directly anterior to the deciduous molariform tooth. Two functionless incisors in each quadrant also were observed during development.
