Risk factors for traumatic dental injuries in the Brazilian population: A critical review.

BACKGROUND/AIMS: Strategies for the prevention of traumatic dental injuries (TDI) should consider the risk factors involved for each population studied. The aim of this study was to perform a critical review regarding the risk factors for TDI in the Brazilian population.

MATERIALS AND METHODS

A systematic literature search was performed in the MEDLINE, Scopus, Web of Science, Lilacs, and BBO databases using MeSH terms, synonyms, and keywords, with no language or date restrictions. In the first step, all relevant studies identified, regardless of the type of statistical analysis performed, were grouped according to their geographic location. In a second step, the studies using Andreasen's criteria to classify the injuries and multivariate analysis to identify the risk factors for TDI in Brazilian subjects were included for data extraction.

RESULTS

The search strategy initially identified 3373 articles. However, only 108 articles assessed TDI with predisposing factors and were included in the first step. From those, 28 were deemed eligible for inclusion in the second step. No consensus related to the relationship between gender and TDI in the primary dentition was achieved. Nonetheless, males were found to be more prone to trauma in the permanent dentition. Overjet, inadequate lip sealing and anterior open bite increased the risk for TDI, both in primary and permanent dentitions. Social environment was related to trauma only in primary dentition. For permanent dentition, dental caries, obesity, binge drinking, and drug use were identified as considerable risk factors for TDI.

CONCLUSION

The risk factors for TDI in the Brazilian population are similar to those found worldwide. However, some differences can be observed, such as gender and socioeconomic indicators as predisposing factors.
