Abstract
The traumatic bone cyst is characterized by the presence of an asymptomatic sinus devoid of epithelial lining, which is rarely found in the jaws. ObjectiveTo describe the clinical, surgical and radiographic findings of traumatic bone cysts. Material and MethodA retrospective study was made of patients diagnosed with traumatic bone cysts at an oral pathology department from 1992 to 2007. Data on the clinical, radiographic and surgical complications were gathered. ResultsTwenty-six cases of traumatic bone cyst were diagnosed in 15 years; 17 were male and 09 were female. Most patients were within first two decades of life and had no pain or history of trauma in the affected area. The multilocular pattern was observed in only seven cases, its radiographic appearance suggests a tumor. Air was found inside the lesion in about 70% of cases; serous fluid with blood and blood only were uncommon within the lesions. ConclusionA higher prevalence in young patients, absence of a history of trauma, and a small number of lesions containing serous fluid with blood reflects the need to discuss the true pathogenesis of traumatic bone cysts.

Summary
Traumatic bone cysts may be characterized by the presence of an asymptomatic cavity in bone with no epithelial lining. Traumatic bone cysts may be classified as unicameral[3], simple[4], solitary[5], hemorrhagic[6], or idiopathic[7]. They are usually asymptomatic and appear on routine radiographies. Because of a lack of unique clinical and radiographic features, it is important to establish the differential diagnosis between traumatic bone cysts and other bone lesions of the jaws – especially translucent lesions. The purpose of this study was to describe the clinical, surgical, and radiographic features of traumatic bone cysts that were diagnosed at an oral pathology center during a 15-year period
