Abstract

A total of 317 mandibular fracture patients treated and diagnosed at the Oulu University Hospital and at the Department of Oral and Maxillofacial Surgery, University of Oulu, Finland, between 1981 and 1990 were analyzed from patient files and radiographs. The mean number of mandibular fracture patients per year was 31.7 (range 21 and 45) and the mean age of the patients 31.3 years (range 4-78 years). The female:male ratio was 1:3.1. There seemed to be a tendency for decrease in the proportion of violence and traffic accidents as causes of mandibular fractures toward the end of the period concerned, reflecting partly the influence of mandatory use of safety belts and partly that the hospital in the northernmost part of Finland, where the consumption of alcohol is higher than in the province of Oulu, could treat all mandibular fractures itself during the last year studied thus decreasing the injuries caused by violence at the Oulu University Hospital. It was also noted that fewer fractures were caused at weekends than on weekdays during the latter years of the decade and that the proportion of male victims decreased except for the last year examined, 1990.
