The expression of genes involved in the Sonic Hedgehog signalling pathway, including Shh, Ptc, Smo, Gli1, Gli2 and Gli3, were found to be expressed in temporal and spatial patterns during early murine tooth development, suggestive of a role in early tooth germ initiation and subsequent epithelial-mesenchymal interactions. Of these Ptc, Smo, Gli1, Gli2 and Gli3 were expressed in epithelium and m...

We analyzed the protein distribution of two cadherin-associated molecules, plakoglobin and β-catenin, during the different stages of tooth development and tooth replacement in zebrafish. Plakoglobin was detected at the plasma membrane already at the onset of tooth development in the epithelial cells of the tooth. This pattern remained unaltered during further tooth development. The mesenchymal ...

this report describes a case of an eight years old girl who was treated for complicated crown fracture of right maxillary central incisor because of a sport accident. for the tooth total pulpotomy was performed in order to achieve apexogenesis and the tooth was restored with a composite resin. the patient was reviewed over 10 years. at first the tooth showed continued root development and compl...

Organogenesis depends upon a well-ordered series of inductive events involving coordination of molecular pathways that regulate the generation and patterning of specific cell types. Key questions in organogenesis involve the identification of the molecular mechanisms by which proteins interact to organize distinct pattern formation and cell fate determination. Tooth development is an excellent ...

Introduction: Hypodontia is one of the most common developmental anomalies. This study aimed to evaluate the variations of radiographic dental development in a group of Iranian children with dental agenesis. Materials and Methods: This study evaluated 1230 Orthopantomographs (OPGs) for agenesis of permanent teeth obtained from the patients aged between 8 and 18 years. Then the difference betwe...

Tooth development is a highly heritable process which relates to other growth and developmental processes, and which interacts with the development of the entire craniofacial complex. Abnormalities of tooth development are common, with tooth agenesis being the most common developmental anomaly in humans. We performed a genome-wide association study of time to first tooth eruption and number of ...

Introduction: Complex molecular pathways involve in development of different tissues such as teeth. Differential gene expression patterns during teeth development generates different tooth types. Teeth development results from interactions between oral epithelium and underlying ectomesenchyme cells with neural crest origin. Teeth development are regulated by different signaling networks. In thi...

Tooth development depends on multiple molecular interactions between the dental epithelium and mesenchyme, which are derived from ectodermal and ectomesenchymal cells, respectively. We report on a systematic RNA sequencing analysis of transcriptional expression levels from the bud to hard tissue formation stages of rat tooth germ development. We found that GNAO1, ENO1, EFNB1, CALM1, SIAH2, ATP6...
