Micromolar fluoride alters ameloblast lineage cells in vitro.
Also, its presence in mesenchyme will result in pre- odontoblasts and odontoblasts (35) Stages of tooth Reported or related functions development in mice Dental lamina (E11) Bud (E12, E13-5,5) Cap (E14, E15-5,5) Jag2 apparently regulates apoptosis levels mediated by enamel node and tooth morphogenesis (14) Bell (E16,5-E18,5) Jag2 is involved in odontoblasts and ameloblasts differentiation and in the subsequent deposit of matrix of enamel and dentin (14)
Environmental conditions thought to affect ameloblast function range from ill-health during pregnancy to perinatal medical conditions such as premature birth and low birth weight to early childhood acute illnesses including pneumonia and unexplained high fever [Chawla et al.
The minimum time period effective enough to cause abnormal ameloblast function is likely to depend on the sensitivity of the ameloblasts to the harmful factor and the power/concentration of this factor.
Researchers at the Forsyth Institute in Massachusetts, a fluoride research center for the past century, found that fluoride initiates an ER stress response in ameloblasts that interferes with protein synthesis and secretion--culminating in dental fluorosis.
24) This cytokeratin expression profile suggests that odontomas are analogs of the developing tooth germ that lack complete differentiation of preameloblasts or ameloblasts and display abnormal enamel organ mineral ization.
This may reflect the direct effect of these antibiotics on active ameloblasts or may be attributed to the infectious disease for which antibiotic was prescribed.
Vitamin A plays a crucial role in the formation of ameloblasts and odontoblasts.
As the odontoblasts express BMP, it induces ameloblasts to differentiate.
By tracing the descendants of genetically labeled cells, they also showed that Sox2 positive stem cells give rise to enamel-forming ameloblasts as well as other cell lineages of the tooth.
