Resumen:
Background: The frequency of traumatic dental injuries (TDI) in primary dentition and those agents that favor
them present a great variability. Therefore, the objective of this study was to determine the prevalence of TDI in a
population of Spanish preschoolers in temporary dentition and identify the factors associated with these injuries.
Materials and Methods: an epidemiological observational prevalence study was carried out. A total of 343 children

Results: the prevalence of TDI in the total sample was 12.2%. The most frequent lesion was crown discoloration
(0.4%) followed by crown fracture (0.1%) and avulsion (0.1%). The most affected tooth was the deciduous upper
central incisor. In the multivariate logistic ...
