PURPOSE: To date, no studies have analyzed the national demographics of @entity174 in the United States. This report is part 1 of a 2-part series characterizing the modern demographics, epidemiology, and outcomes of @entity174 in the United States. The purpose of this study was to characterize @entity174 in relation to age, gender, mechanism of injury, and anatomic location of @entity174 . MATERIAL AND METHODS: A retrospective cohort study was conducted using the National @entity130 Data Bank (NTDB). The sample was derived from the population of hospitalized @entity1 enrolled in the NTDB from 2001 to 2005 using mandibular @entity174 (International Classification of Diseases, Ninth Revision codes 802.21 through 802.39) as an inclusion criterion. @entity1 - and injury-related variables, including age, gender, anatomic location of @entity174 , and mechanism of injury, were analyzed by Fisher exact and   (2) testing. RESULTS: A total of 13,142 @entity1 with @entity174 from participating @entity130 centers were included in the study. Eighty percent of @entity1 were male. @entity174 distribution by age was roughly bell-shaped, with @entity174 occurring most frequently at 18 to 54  years of age. @entity130 differed by gender, with @entity1 most often sustaining mandibular @entity174 from assault (49.1%), followed by @entity64 ( @entity64 ; 25.4%) and falls (12.8%). @entity1 most commonly sustained mandibular @entity174 from @entity64 (53.7%), followed by assault (14.5%) and falls (23.7%). Falls were a significantly more common mechanism in @entity1 who were at least 65  years old (P < .001). CONCLUSION: This study sought to characterize the largest, modern, population-based sample of @entity174 in the United States. Overall, @entity1 had a 4-fold higher incidence, but this distribution varied by age. Similarly, mechanism of injury varied across gender and age range. A better understanding of the influence of age and gender on mechanism of injury and anatomic site is of great clinical importance in the assessment, diagnosis, and treatment of @entity174 .
