Pitting enamel hypoplasia

[1] One of the most common types, pitting enamel hypoplasia (PEH), ranges from small circular pinpricks to larger irregular depressions.

[2] Pits also vary in how they occur on a tooth surface, some forming rows and others more randomly scattered.

It has been suggested that because it is relatively rare to have both linear enamel hypoplasia and PEH, these types of defects may be commonly caused by different factors.

[6] This does not occur in other forms of enamel hypoplasia, such as linear and plane-form, in which all ameloblast activity is affected.

[4] Typically with PEH described in archaeological reports, researchers can not specify a cause, with a non-specific stress often concluded.
