In the first quarter of 1985, the use of the seat belts in every car was compulsory as disposed by law and it was discontinued afterwards. The authors correlate the number and type of facial fractures in patients admitted to the Emergency unit of the Hospital das Clínicas of University of São Paulo Medical School, during the first quarter of 1984, 1985 and 1986. A significant decrease of the number of cases and the severity of the facial fractures during the 1985 period was observed and, more important, a decrease was noted on the proportion of the nasal and fronto-orbital fractures among the overall number of fractures of the face. There was thus a significant relationship between the use of belts and the number and severity of the facial fractures.
1985年第一季度，法律规定每辆汽车必须使用安全带，之后该规定被废止。作者对1984年、1985年和1986年第一季度入住圣保罗大学医学院临床医院急诊科的患者面部骨折的数量和类型进行了关联分析。观察到1985年期间面部骨折的病例数量和严重程度显著下降，更重要的是，在面部骨折总数中，鼻骨和额眶骨折的比例有所下降。因此，安全带的使用与面部骨折的数量和严重程度之间存在显著关系。
