Osteogenesis imperfecta and odontogenesis imperfecta
Oral Surgery, Oral Medicine, Oral Pathology, 1949Abstract 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.

Epigenetics in Odontogenesis and its Influences
Current Stem Cell Research & Therapy, 2018Odontogenesis 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.

Effects of a sclerosing agent on odontogenesis
Oral Surgery, Oral Medicine, Oral Pathology, 1971Abstract 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.

The effects of cyclophosphamide on odontogenesis in the rat
Archives of Oral Biology, 1975Abstract Twelve Wistar rats weighing 250–400 g were divided into four groups. Three groups were given respectively 40, 80 and 120 mg cyclophosphamide per kg by single intraperitoneal injections. The fourth, control, group was given 2 cm 3 normal saline. One animal from each group was killed after 1, 4 and 8 days.

Odontogenesis in the Veiled Chameleon (Chamaeleo calyptratus)
Archives of Oral Biology, 2013Replacement teeth in reptiles and mammals develop from a successional dental lamina. In monophyodont (single generation) species such as the mouse, no successional lamina develops. We have selected a reptilian monophyodont species - the Veiled Chameleon (Chamaeleo calyptratus) - to investigate whether this is a common characteristic of species that do ...

Molar odontogenesis in the trisomic 16 mouse
Archives of Oral Biology, 1993Stocks used were male and female monozygotes for Robertsonian translocation specific for chromosomes 16 and 17 Rb(16.17)7Bnr and males and females homozygous for Robertsonian translocation for chromosomes 6 and 16 Rb(6.16)24Lub to produce double heterozygotes characterized as Rb(16.17)Bnr/Rb(6.16)24Lub.

The disturbances in odontogenesis in epidermolysis bullosa hereditaria letalis
Oral Surgery, Oral Medicine, Oral Pathology, 1975The disturbances in odontogenesis in a case of epidermolysis bullosa hereditaria letalis are described, with particular emphasis on the morphologic alterations in the ameloblasts and on the nature of vesicles in the enamel organ. These latter structures are compared to those found in the skin.

The Genetic Control of Early Odontogenesis
British Journal of Orthodontics, 1999Odontogenesis is a highly co-ordinated and complex process which relies upon cell-to-cell interactions that result in the initiation and generation of the tooth.

Neuronal cells and neurotrophins in odontogenesis
European Journal of Oral Sciences, 1998There 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.

Expression of p21WAF1/CIP1 during mouse odontogenesis
European Journal of Oral Sciences, 1998p21WAF1/CIP1 is a cyclin‐dependent kinase (Cdk) inhibitor. This protein may function during development as an inducible growth inhibitor that contributes to cell cycle exit and differentiation. The expression pattern of p21 during mouse embryogenesis was correlated with terminal differentiation of multiple cell lineages including skeletal muscles ...
