Enamel hypocalcification
Some areas in Enamel are hypocalcified.they are Enamel spindles, Enamel tufts, Enamel lamellae.
Enamel Hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced
but are hypomineralized. In this defect the enamel is softer than normal.
Etiologic factors may occur locally, affecting only a
single tooth, or they may act systemically, affecting all
teeth in which enamel is being formed. Local trauma
or abscess formation can adversely affect the
ameloblasts overlying a developing crown, resulting
in enamel hypocalcification or hypoplasia. Affected
teeth may have areas of coronal discoloration, or they
may have actual pits and irregularities. This is most
commonly seen in permanent teeth in which the
overlying decididous tooth becomes abscessed or is
physically forced into the enamel organ of the permanent
tooth
. The resulting hypoplastic or hypocalcified
permanent tooth is sometimes known as Turner's tooth.
