Term | Definition |
---|---|
Stellate Reticulum Cells | A group of cells located in the center of the enamel organ of a developing tooth. -Star shaped cells (protect underlying dental tissues & maintain the shape of tooth) -Synthesizes glycosaminoglycans |
Stratum Intermedium Cells | A stratified layer of cells located between the inner enamel epithelium & the stellate reticulum. -responsible for tooth enamel formation with inner enamel epithelium. |
Outer Enamel Epithelial Cells | (External enamel epithelium) A layer of cuboidal cells located on the periphery of the enamel organ in a developing tooth. -First seen during Bell Stage of tooth development. -Enamel organ is composed of Outer Epithelial cells |
Inner Enamel Epithelial Cells | Innermost layer of odontogenic organ, which develops into the enamel-producing ameloblasts. -located on rim nearest to the dental papilla of the enamel organ. |
Amelogenesis Imperfecta | A group of developmental conditions which affect the structure and clinical appearance of enamel of all or nearly all teeth in a more or less equal manner. (may be associated with morphologic or biochemical changes elsewhere in the body. ) |
Reduced Enamel Epithelium | epithelial covering of the enamel after its formation is completed. -functions as protective layer - takes place on enamel surface |
