Background: The fractures of the mandible are common facial injuries, and their consequences have remained a burden in dental and oral surgery practice. To review patients with mandibular fractures at our institution over a 4-year time frame of 10 years apart between 1997–2000 and 2011–2014 and compare the trends in the number of cases. Materials and Methods: The hospital register and case notes of the patients with mandibular fractures were retrospectively reviewed to obtain relevant information concerning the socio-demographic data and clinical characteristics of the fractures. Results: There was a reduction in the number of patients and fractures when the 2011 study (168 patients and 239 fractures) was compared with the 1997 study (358 patients and 474 fractures), and this was significant (P = 0.001). Road traffic accidents were the most common cause of fractures; motorcycle-related traffic accidents were more frequent in the years 1997–2000 (n = 128, 35.7%) than that in the years 2011–2014 (n = 11, 6.6%); vehicular road traffic accidents were more common in the years 2011–2014 (n = 123, 73.2%) than that in the years 1997–2000 (n = 153, 42.7%), and these were significant (P = 0.001). Mandibular fractures were more of isolated fractures and less associated with concomitant injuries in the 2011 study than that in the 1997 study (P = 0.001). There was a significant reduction of complications in the 2011 study (P = 0.001). Conclusion: This study has shown that the frequency of mandibular trauma has changed significantly over the past decade, which may be explained in terms of the ban on the use of motorcycle for public transportation.
