Context
- After trauma to primary incisors, it is essential to consider the possible risks of sequelae in successor teeth.
- The developmental disturbances of the permanent teeth related to trauma to their predecessors have a prevalence that ranges from 20% to 74% 3–10 related to the close anatomical relationship between the apices of the primary teeth and their developing permanent successors 10, 11.
Purpose of the Review
- To examine scientific evidence that trauma in the primary incisors cause sequelae in permanent successors.
- To verify the existence of a relation between the presence and type of sequelae in permanent teeth with the child’s age at the time of injury and type of trauma.
Key Findings
- Despite limitations, evidence suggests that individuals with trauma in their primary incisors have more developmental disorders in the permanent successors than individuals without a previous trauma.
- The younger the child is at the time of injury, the more frequent and more severe are the sequelae to the permanent successor incisors.
- More severe traumas, such as intrusion and avulsion, are associated with more serious developmental disorders.
