Materials and Methods: The present study is a case-control study in which 120 patients admitted to the maxillofacial ward of Bahonar Hospital in Kerman from June 2016 to Aguste 2016 were investigated. The case group included 60 drivers admitted to the ward due to maxillofacial injury, and the control group included 60 non-drivers (driver assistant or pedestrian) admitted to the ward. A random convenient sampling method was used. Patients were asked to carefully complete Minnesota Multiphasic Personality Inventory -71 (MMPI-71) scale. Collected data were analyzed using SPSS software.

Results: Mean age of participants in the case and control groups were 25.83 + 4.08 and 24.95 + 4.40 years, respectively, which showed no statistically significant difference (p>0.05). Fifty-two patients (86.7%) in the case group and 54 patients (90%) in the control group were men, which implied no significant difference in terms of gender distribution (p<0.05). Also, the mean mania scale score was 55 + 9.02 in the case group and 52 + 7.02 in the control group, which showed no statistically significant difference (P<0.05).

Conclusion: Findings of the present study suggest no relationship between the road injuries in drivers admitted in the maxillofacial surgery of Bahonar Hospital in Kerman and the prevalence of the psychological disorders.
