A patient gives a history of previous chronic abscess on the deciduous precursor of 11. The following radiograph indicates:
Turner’s Hypoplasia
This condition represents a defect occurring during amelogenesis that is the result of either local trauma or infection originating from the deciduous predecessor.
Radiological signs
If the deformity is minimal, the tooth will show a localized area of hypoplasia. A prolonged disturbance will lead to pronounced changes in tooth morphology that include gross deformity, irregularity and a reduction in crown size.
