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.
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.
Enamel spindles are often confused with two other entities: enamel lamellae and enamel tufts. Lamellae are linear enamel defects that extend from the surface of the enamel towards the DEJ, or vice versa. Enamel tufts are "small, branching defects that are found only at the DEJ, protruding into the enamel towards the enamel surface.
Enamel hypoplasia and enamel hypocalcification are examples of defective enamel that potentially gives a discolored appearance to the tooth.
