RESUMO
OBJECTIVE: To compare the location and multiplicity of mandibular fractures in Kuwait, Canada and Finland during the 1990s. SUBJECTS AND METHODS: Data were collected from several hospitals in Kuwait (1991-2000), Toronto General Hospital in Canada (1995-2000) and Oulu University Hospital in Finland (1990-1999). The data were analyzed statistically using chi-square test, ANOVA, t test and logistic regression. RESULTS: Condylar fractures were more common in Finnish patients (41%) than Canadian (35%) or Kuwaiti patients (21%). Condylar fractures caused by falls were about 3.4 times more common in Kuwait and Finland compared to Canada. In Finland the risk of road traffic accidents caused by condylar fracture was about 4 times higher than those caused by other etiologies. In Canada male gender was about 2 times higher for the condylar fracture than female gender. Female patients often had more multiple injuries than men in all three countries and multiple fractures were observed especially in traumas caused by falling. CONCLUSION: Differences in location and multiplicity of mandibular fractures are due to differences in etiologies and demographic patterns.

We studied causes of mandibular fractures treated in oral and maxillofacial units in three countries in years 1990-2000 in Kuwait (n=596), 1995-2000 in Canada (n=228), and 1990-99 in Finland (n=268). Of the Finnish patients, 27% were women. Corresponding percentages in Kuwait and Canada were 13 and 17%, respectively. Traffic crashes were the cause of injury in 55% of the cases in Kuwait and 33% in Oulu, but only 7% in Toronto. In Kuwait, the victims were often young people, which is why more traffic education, more control of speed, and more control of the use of safety belts should be implemented. Assault was the cause in 54% in Toronto, 12% in Kuwait, and 37% in Oulu. Falling was the cause in 22% of the cases in Kuwait. Alcohol was implicated in 21% of cases in Canada and 15% in Finland.
