Abstract (English):	Background Mandible occupies the second place in frequency as site of facial fractures. Most frequent causes are automobile accidents and violent assaults. Characteristics of fractures depend on factors as anatomical structures with weak areas or the existence of non-erupted third molars. Objective To determine most frequent causes of mandibular fractures in patients treated at the Hospital Central Militar de Mexico, as well as the affected anatomical regions. Material and methods Retrospective study of cases with diagnosis of mandibular fracture, since January 1, 1997, until December 31, 2001. Cases with data of age, genre, site of the fracture and cause of the traumatism were included. Results Forty-one patients (39 male and two female) with ages were between 17 and 57 years (mean of 29.9). Most frequent cause of fracture was urban violence (41%), followed by car accident (29%), fall accidents (17%), sport injuries (5%), firearm wound (5%), and auto running down (3%). Most affected anatomical place was mandibular angle (33.8%), followed by mandibular symphysis (30.8%). Male gender suffered most of the trauma (95%). Conclusion Results coincide with similar studies. Existence of an impacted third molar increases incidence of these fractures significantly. [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	ANTECEDENTES La mandíbula ocupa el segundo lugar en frecuencia como sitio de fracturas faciales. Las causas más frecuentes son los accidentes automovilísticos y el asalto violento. Las características de la fractura dependen de factores como las estructuras anatómicas con zonas débiles o la existencia de terceros molares no erupcionados. OBJETIVO Determinar las causas más frecuentes de fractura mandibular en los pacientes tratados en el Hospital Central Militar de México, así como las regiones anatómicas más afectadas. MATERIAL Y MÉTODOS Estudio retrospectivo de casos con diagnóstico de fractura mandibular tratados entre el 1 de enero de 1997 y el 31 de diciembre de 2001. Se seleccionaron expedientes que incluyeran la edad, el sexo, el sitio de la fractura y la causa del traumatismo. RESULTADOS De un total de 41 pacientes, 39 eran masculinos y dos, femeninos. El rango de edad fue de 17 a 57 años, con un promedio de 29.9. La causa más frecuente de fractura fue la violencia urbana (41%), seguida por los accidentes automovilísticos (29%), caídas (17%), lesiones en actividades deportivas (5%), heridas por arma de fuego (5%) y atropellamiento por vehículo automotor (3%). El sitio anatómico más afectado fue el ángulo mandibular (33.8%), seguido por la región parasinfisiaria (30.8%). El sexo masculino padeció 95% de los casos. CONCLUSIÓN Los resultados obtenidos coinciden con estudios similares. La existencia de un tercer molar impactado incrementa significativamente la incidencia de estas fracturas. [ABSTRACT FROM AUTHOR]
