Enamel hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. [ 1 ] [ 2 ] In this defect the enamel is softer than normal. Some areas in enamel are hypocalcified: enamel spindles, enamel tufts, and enamel lamellae.
Enamel spindles are "short, linear defects, found at the dentinoenamel junction (DEJ) and extend into the enamel, often being more prevalent at the cusp tips." [ 1 ] The DEJ is the interface of the enamel and the underlying dentin .
Dental fluorosis is a common [2] disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [3] [needs update]
Enamel hypoplasia and enamel hypocalcification are examples of defective enamel that potentially gives a discolored appearance to the tooth. Teeth affected in this way are also usually more susceptible to further staining acquired throughout life. Amelogenesis imperfecta is a rare condition that affects the formation of enamel (amelogenesis ...
Hypomineralization or hypocalcification, as opposed to hypoplasia, refers to a decrease in the mineral content of the enamel, not the total amount present. It can vary in its presentation, and teeth may appear visually normal or highly translucent. Affected enamel is softer and more susceptible to acid, wear and decay.
Low-fat dairy is another category of high-protein options that are easy to use and found at a reasonable price. Low-fat milk, yogurt and cottage cheese are all excellent sources of protein that ...
Enamel tufts are small branching defects that are found only at the DEJ, and so differ from lamellae which can be facing either direction and are strictly linear. Enamel spindles are also linear defects, but they too can be found only at the DEJ, because they are formed by entrapment of odontoblast processes between ameloblasts prior to and ...
