− | This condition is a consequence of abnormalities occurring during the period of tooth eruption.

The [[Enamel Organ#Enamel|enamel]] is marked by pits and lines etc. | + | This condition is a consequence of abnormalities occurring during the period of [[Tooth Eruption|tooth eruption]].

| Hypoplasia may also occur in single teeth following damage to the permanent tooth germ, for example if a deciduous tooth is fractured or extracted without care. The damaged ameloblasts will fail to form enamel and abnormalities will be evident. | | Hypoplasia may also occur in single teeth following damage to the permanent tooth germ, for example if a deciduous tooth is fractured or extracted without care.
