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.
Inadequate amounts of vitamin C results in changes in the ameloblasts and odontoblasts; ameloblasts and odontoblast atrophy, and there is a decrease in their orderly polar arrangement.
8) It has also been recently shown that since exposure to fluoride can inhibit protein synthesis, fluoride may therefore induce endoplasmic reticulum stress in ameloblasts responsible for dental enamel formation.
Given their similar location and their large numbers of basally-directed secretion granules, the cells of the primordial spine's ectoderm-derived pseudostratified columnar epithelial layer may be identified as ameloblasts.
Second, the interference by TCDD with the formative stage of tooth development--that is, the function of secretory ameloblasts and odontoblasts--results in delayed or defective mineralization of the molar teeth (Gao et al.
In marsupials, tubules are described as hollow spaces formed by the course of ameloblasts, occurring within or outside of prisms, and sometimes continuous with dentine tubules across the enamel-dentine junction (Boyde and Lester, 1967).
Its production begins with a matrix of amelogenin, produced by cells called ameloblasts, along with the less abudant protein enamelin.
At the secretory stage, ameloblasts secrete large amounts of enamel matrix proteins within which long thin ribbons of enamel mineral, mainly hydroxyapatite, are formed almost immediately the enamel matrix is laid down.
Characterized by pits, furrows, or swales on the surface of teeth, enamel hypoplasia is a permanent record of disturbances that hinder the development of ameloblasts (cells responsible for enamel deposition).
The development of enamel opacities implies that ameloblasts are affected during the enamel maturation stage.
Sicher and Bhaskar [1972] suggested that disturbances during the morphodifferentiation stage, such as altered endocrinic function, may affect the shape and size of the tooth without impairing the function of the ameloblasts and odontoblasts.
The tumor is made up of a blend of ameloblasts and epithelial cells that try to duplicate the enamel organ.
Demarcated hypomineralisation defects are thought to have a multifactorial aetiology with pathogenesis occurring during the pre-, peri- or post-natal period and disturbing the ameloblasts during the later mineralisation phase of amelogenesis [Jalevik and Noren, 2000].
Amelogenesis involves the formation of enamel by sheets of cells called ameloblasts.
Characterized by pits, furrows, or grooves on the surface of teeth, enamel hypoplasia is a permanent record of disturbances that hindered the development of ameloblasts (cells responsible for enamel deposition).
