摘要

A retrospective study was performed in 100 dogs with 121 mandibular and 21 maxillary fractures. Dogfight (43.0 %) and automobile (12.0 %) trauma were the most common etiologies for fracture. The cause of fracture was unknown in 23.0 % of the cases, while pathologic fractures occurred in 13.0 % of cases. Young dogs (< 1-year-old) and dogs > 8-years of age were most affected. Mandibular fractures occurred in 90 dogs (90.0 %), with two dogs (2.2 %) having concurrent maxillary fractures. Maxillary fractures only were diagnosed in 10 dogs (10.0%). The molar region (47.1 %) was the most commonly affected location for mandibular fracture, followed by fractures of the symphysis and parasymphysis (30.6 %), premolar region (17.4 %), angular process (4.1 %) and vertical ramus (0.8 %). In fractures of the mandibular region, the mandibular first molar tooth was often (85.9%) involved while the canine teeth were involved in 67.5 % of symphyseal and parasymphyseal fractures. The most common fracture of the maxilla was the maxillary bone (52.4 %), followed by the incisive (33.3 %), palatine (9.5 %), and nasal (4.8 %) bones.
