Odontogenesis is a highly co-ordinated and complex process which relies upon cell-cell interactions that result in the initiation and generation of tooth. Molecular changes that correlate with advancing tooth morphogenesis have been mapped by many research groups. Here, we review some of the current literature concerning molecular regulation of odontogenesis. Key-Words: Odontogenesis; tooth for...

Odontogenesis results from the continuous and reciprocal interaction between cells of the oral epithelium and cranial neural crest-derived mesenchyme. The canonical Wnt signaling pathway plays a fundamental role in mediating these interactions from the earliest stages of tooth development. Here we analyze by in situ hybridization the expression patterns of the extracellular Wnt antagonist Frzb/...

Rapid increase of knowledge in stem cell research, bioengineering technology and molecular basis of odontogenesis has finally lead us to the point where it is possible to develop approaches for treatment of tooth loss with bioengineered teeth, which one day might completely replace conventional prosthodontics and dental implants. By holding onto the premise that in order to bioengineer teeth, f...

Important factors involved in odontogenesis in mouse dental papillae disappear between the pre- and post-natal stages of development. Therefore, we hypothesized that certain genes involved in odontogenesis in dental papillae were subject to pre-/post-natal down-regulation. Our goal was to identify, by microarray analysis, which genes were down-regulated. Dental papillae were isolated from embry...

odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. the lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

In this report, we present the case of a girl with delayed odontogenesis of a lower second premolar for which she was followed up for 8.5 years. Congenital absence of permanent mandibular second premolars was observed at the initial radiographic examination at 8 years and 1 month. One year later, during the treatment period, an unexpected odontogenesis of a right second premolar was diagnosed o...

Carbonic anhydrases (CAs) play fundamental roles in several physiological events, and emerging evidence points at their involvement in an array of disorders, including cancer. The expression of CAs in the different cells of teeth is unknown, let alone their expression patterns during odontogenesis. As a first step towards understanding the role of CAs during odontogenesis, we used immunohistoch...
