Intrusion injuries of primary incisors. Part III:   Effects on the permanent successors.
Intrusion injuries of the primary dentition are highly associated with developmental disturbances of their successor teeth. The age of the child at the time of injury, the direction and severity of the intrusion, and the presence of alveolar bone fracture are important variables influencing the effect of primary tooth intrusion on the developing permanent germ. The developmental defects of the permanent successor tooth range from mild alteration in enamel mineralization to severe sequestration of the developing germ. This article will review the developmental anomalies of the permanent incisors induced by intrusion injuries of their predecessors.
