Sequelae in permanent dentition after trauma in primary dentition in patients assi-sted at Hospital Base Valdivia, Chile

Aim: To determine the type and frequency of sequelae in permanent teeth as a result of traumatic dental injuries in primary teeth in pediatric patients attended to at the Hospital Base Valdivia, between 2007 and 2012. Material and Methods: A descriptive study was conducted. The medical records of pediatric patients who were affected by traumatic dental injuries in primary teeth and went to the Sub-department of Dentistry of the Hospital Base Valdivia, Chile, were selected according to inclusion and exclusion criteria. The recorded data was: age of the child at the time of the accident, gender, affected primary tooth, type of traumatic dental injuries, and diagnosis of the permanent successor tooth. Descriptive statistics were performed. A chi-square test was used to establish differences between type of traumatic dental injuries and condition of the permanent tooth. Results: The most frequent diagnosis of traumatic dental injuries in primary dentition was subluxation. The primary tooth with the highest frequency of traumatic dental injuries was the right maxillary central incisor; 58.2% of the permanent successors presented some developmental disturbances. The most frequent sequelae observed in permanent teeth were chronological alterations of the eruption. Conclusion: There is a high frequency of sequelae in permanent dentition as a result of trauma in primary dentition. The most frequent sequel observed was chronological alteration of the eruption. It is fundamental to inform parents about the possible consequences that could arise and emphasize the importance of attending periodic follow up in order to prevent or minimize possible sequelae in permanent teeth.
