Amelogenesis
Pronunciation: ah-mel-oh-JEN-eh-sis
The biological process by which enamel is formed on the crowns of teeth during tooth development.
Full Definition
Amelogenesis refers to the formation of dental enamel, the hardest tissue in the human body, produced by specialized cells called ameloblasts during the crown stage of tooth development. The process occurs in two main phases: the secretory phase, in which enamel matrix proteins are deposited, and the maturation phase, in which the matrix is mineralised. In dental research publications, authors must distinguish amelogenesis from dentinogenesis and cementogenesis, which describe the formation of dentin and cementum respectively. Disruptions to amelogenesis result in a group of hereditary conditions collectively termed amelogenesis imperfecta. Editorial care is needed to avoid conflating this developmental process with the mature structural properties of enamel itself.
Usage
Usage note: Do not hyphenate. Distinguish clearly from 'amelogenesis imperfecta,' which is the pathological condition, not the process itself.
