Neurotrophins in odontogenesis

The International Journal of Developmental Biology, 1995
Neurotrophins (NTFs) are a family of structurally related proteins with specific effects on the developing nervous system and a wide range of non-neuronal differentiating cells. To date, four NTFs have been characterized: nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4).

Methylphenidate effects on mice odontogenesis and connections with human odontogenesis

Odontology, 2020
The purpose of this study is to evaluate the effects of Methylphenidate exposure on mice odontogenesis and connect them by bioinformatics with human odontogenesis. Thirty-two pregnant Swiss mice were divided into treated group and control group, which received, respectively, 5 mg/kg of Methylphenidate and saline solution from the 5th to the 17th day of

Epigenetics in Odontogenesis and its Influences

Current Stem Cell Research and Therapy, 2018
Odontogenesis is fundamentally controlled by the genome. However, epigenetic factors have indispensable effects during odontogenesis. Previous studies have shown that exogenous factors, such as the environment, that cause hypomethylation and hypermethylation in DNA may lead to dental differences in monozygotic twin pairs.

Mucopolysaccharides in odontogenesis

Histochemie, 1970
Localization of sulfomucopolysaccharides in developing teeth of Swiss albino mice was detected by S35 autoradiography and histochemistry. A positive correlation was found to exist between autoradiographic and histochemical data with regard to the localization of sulfomucopolysaccharides.

Molar odontogenesis in the hairless mouse

Cells Tissues Organs, 1977
Molar odontogenesis was studied in the hairless mouse from the initiation of the dental lamina through apposition. The dental lamina stage of the first molar was recognized on the 13th day, the bud on day 14th, cap on the 16th, bell on the 18th and apposition on the 20th day after conception.

Effects of a sclerosing agent on odontogenesis

Oral Surgery, Oral Medicine, Oral Pathology, 1971
Abstract The effects of sodium tetradecyl sulfate on odontogenesis were studied in three rhesus monkeys. This sclerosing agent was not completely effective in inhibiting the development and growth of all of the injected teeth. The results were encouraging, and more extensive studies have been recommended.

Growth hormone and odontogenesis [PDF]

, 2023
Children with dwartism have impertect tooth development and delayed tooth eruption. This is thought to be due to a lack of growth hormone or of cell receptors for the hormone. However, the mechanism of action of the hormone on tooth forming cells is unknown.

Osteogenesis imperfecta and odontogenesis imperfecta

Oral Surgery, Oral Medicine, Oral Pathology, 1949
Abstract A review of the pertinent literature is presented. Conspicuous by its absence is any record of a fracture of a mandible or maxilla. A family of 13, 5 members of which are afflicted with osteogenesis imperfecta and 2 spontaneous recent mutations, are reported.

The Ectodysplasin and NFκB signalling pathways in odontogenesis

Archives of Oral Biology, 2005
Hypohidrotic ectodermal dysplasia (HED) is a congenital disorder affecting organs of ectodermal origin including teeth, hair and sweat glands. Defects in Ectodysplasin (tabby), Edar (downless) and Edar associated death domain (Edaradd) (crinkled) cause HED in both humans and mice. Ectodysplasin is a tumour necrosis factor (TNF) superfamily member whose

Neuronal cells and neurotrophins in odontogenesis

European Journal of Oral Sciences, 1998
There is evidence from lower animals that in addition to oral ectoderm and cranial neural crest, tooth formation depends on neuronal cells. To analyze the possible neural influence on mammalian tooth formation, peripheral nerve fibers and neuronal cells were localized in the area of the developing rat first molar tooth germ.
